When leaves curl under is that from to much nute are can it be from nute lock? Is there any case where you could have dif. in one (zinc) and to much in another causing curling under?

Hey Al...Can high pH cause this?

 

[Chumlie]

Hey Al this is off the wall question about geting the ph down. YOu think lemon juice would work, are would I kill the plants?

I have a clone I took from a flowering plant, in which I cut it at a 45 deg angle, and then split some of the stem. I also scraped away some of the stem, with some scissors so its not as thick. Its now sitting in a solution of b1, and some superthrive, along with some rooting hormone. Should I let it sit in this solution for a few days, or should I apply root powder on the cutting and plant it in soil?

Also, with whatever one I do, should I foliar feed it? Plants can absorb some nutrients through their leaves but not all of them... will it be able to absorb the plant hormones in superthrive, and b1 vitamins thru the leaves? If I add other things to the foliar feed mix such as fish emulsion, molasses, or some other vegging ferts, will this discourage or slow root growth / or how long it takes to grow them?

Sorry, this is the first clone i've tried to grow :[, and i'm totally amazed at this thread you have going here! I can't beleive you have the patience to answer all these questions, question after question. You must be smoking some good weed. Thank you for all the help youve given us!

Hey Al...Can high pH cause this?

I ask because my plants exhibited signs of nutrient lock, and some signs of burning, along with some chlorosis. Almost every symptom in the diagnosis guide. My pH had gotten too high (like 7.2) and it caused all kinds of funky stuff to happen!!!

hey al b.. i love ur grows and ive been tryin to get something going to imitate yours, but its going slow when the hydro guy tried to tell me it was 4,200 for everything... i know i could get it half the price online / building myself a few things. anyways... question for you, he gave me a business card cuz i told him i had some seeds i was planning on planting and he asked me who i was going to have sex them, i said myself, and anyways the business card is for some guy who supposedly genetically can test a leaf from a tiny plant in veg, lets say just a sample leaf he was telling me. spoof? he says its 100%.... crazy.. he says that way u can pull them and not waste light on them to grow em out before flowering ya know? whats ur thoughts?

 

[fshields1]

hey al, i know that you are more geared towards the hydro buy i was woundering if you knew of any ways to kill fungus gnats and thier larvae in soil. i havent seen any effects to my plants yet but they are every where and when i just transplanted a few of my smaller plants the larvae were all through the soil

 

[Al B. Fuct]

Or maybe switch to running my lights at night. Too lazy to make the switch.

I'd certainly try that first. Everything else sounds like it's well in order.

Me 2! Maybe I should change over and run my lights at night...hmmm.

Hey Al...If I wanted to change my light cycle (like to have the light go on at 6pm instead of on at 6am) and I am 18/6 now, would I just leave them on at the end of 18 until I wanted to end the new cycle and turn the light off? or will that be like giving them LSD? make em all trippy and shit!

AND...when it's time to change the light cycle to 12/12, can I just set a day and go "zap" your on 12/12? or do I need to do it like we used to and slowly change the light cycle over?

Switching the sked for flowering plants is as easy as giving them a long 'night' and beginning the new sked. If you're on 8a-8p now, leave the lights off from 8p to 8p the next day when you can begin your new 8p-8a sked. Switching veg plants is even easier. Just leave them on 24/0 and start the new cycle at any time after they have had at least 18H of light.

Ok...I am using a Green Air Products - Atmospheric Controller model CT-DH-3P. It is a pretty basic unit.

It could use the ability to measure CO2 concentration, which this model doesn't seem to have.

I think I need a bigger exhaust fan. I know it moves air and the air flow in the room is DEFINITELY negative when the fan is running...however. Warm outside temperatures have made it difficult to keep temps below 85 degrees. I'll make that a priority. It'll get easier over the next few weeks as winter sets in and it starts snowing here.

How close does the room air temps stay to the ambient intake air temp?

My light cycle is on 6am - off 12am. From 12am to 6am the pH stays very stable. I flood every 2 hours beginning at 6am. This morning at 5:00 am the pH wa 5.8. At 9am (after 2 feedings) the pH was 6.1. I corrected it back to 5.8.

hmm, ok. When was the last dose of H2O2?

I was hoping at some point I would be able to leave and get groceries without worrying about my plants being damaged when I return...maybe I need better H2O.

No, this isn't a water quality issue. More likely, you may need to apply more H2O2. If there's a lot of pathogen material in the tanks, all the H2O2 may have been reacted and the pathogens are rebounding. Hit 'em again.

No city water here. Straight from the spring to the house. Good water, most of the time. But the pH varies from 7.0 to 8.2 out of the tap.

Your pH swings less than that of my muni tap water (7.1-8.5). Have you gotten a recent analysis of your bore water? Your only real concern is salinity.

You can make a 3 phase converter with a 3 phase motor. Forgot the particulars, but basically you back feed one leg and toss on a pull start.

Yes, that's doable but if I went that route, I think I'd opt for the commercially made dynamotor unit, which starts itself. It's just such a crude way to do it, tho. I'm old enough to remember vacuum tube mobile 2-way radios which used a dynamotor (for the non-electron-junkies here, a dynamotor is a voltage converter- it's a motor which runs on the easily available voltage, which then spins a generator that makes the voltage you want) to make a 250V B+ from 12V, at the cost of a massssssive load on the electrical system. It's a hugely inefficient way to do the job. You'd think there'd be a cost effective solid-state inverter device around to do the 3Φ conversion. I'll keep sniffing.

Or just change the motor to what you got. (cheaper overall)

Could well be. I can afford the mill, got room for it, it's just the lack of 3Φ. I'll check into the cost of replacing the motor with a 1Φ unit. Thanks for the suggestion.

When leaves curl under is that from to much nute are can it be from nute lock? Is there any case where you could have dif. in one (zinc) and to much in another causing curling under?

Usually when I see leaves curling under, it's a nute burn. However, the cause of the nute burn can be a pH error that locks out all but the N.

Any chance you shot high, like 7.0? That looks like it would do it.

Get the pH right (5.8 ) and verify the nutes are at 1400.

Hey Al...Can high pH cause this?

dingdingding.

hey al b.. i love ur grows and ive been tryin to get something going to imitate yours, but its going slow when the hydro guy tried to tell me it was 4,200 for everything... i know i could get it half the price online / building myself a few things.

I think I'd deal with this guy only if I absolutely had to.

anyways... question for you, he gave me a business card cuz i told him i had some seeds i was planning on planting and he asked me who i was going to have sex them, i said myself, and anyways the business card is for some guy who supposedly genetically can test a leaf from a tiny plant in veg, lets say just a sample leaf he was telling me. spoof? he says its 100%.... crazy.. he says that way u can pull them and not waste light on them to grow em out before flowering ya know? whats ur thoughts?

Correction- stay as far away as possible from this hydro shop guy & his mate who claims to sex plants with leaves. That's a crock of shit. I'd be hugely suspicious as to what he's really up to.

hey al, i know that you are more geared towards the hydro buy i was woundering if you knew of any ways to kill fungus gnats and thier larvae in soil.

Try some Gnatrol. Your garden shop or hydro store should have it.

 

[xxtoadxx]

lol <3 the response and thanks for the quickness =) so... 4x600 hps, 4x 3x3 trays ebb n flow flood 3 times a day and ill be good? im going to use the CANNA line of nutes, i heard really great things about it

 

[fshields1]

there are no hydro shops around where i live. iv heard of people putting sand on top of the soil?? any advice there?

 

[Al B. Fuct]

Sand may act as a barrier if you don't now have gnats, but you already do. A barrier will not really help. An better barrier option is to drop the pot in a knee-hi nylon stocking and put a twist-tie around the cuff of the stocking, where it meets the stem.

Check garden shops, many have Gnatrol.

Sounds like a plan, Stan.

I've used Canna nutes for about 10 years, always been happy with them.

 

[xxtoadxx]

oooo one more question, i looked what he charged me for resevoirs...$126/ea x 4 40 gallon resevoirs... do i need that big and is there a cheaper alternative?

the only thig that the garden shops around here have for gnat killer is neem oil, but from what iv read that is for spraying not use in the soil. ill gige the nylon thing a try though. thanks

 

[Al B. Fuct]

About 5L per plant is needed. You can use inexpensive plastic storage boxes/tubs from the local dollar shop as a cheaper alternative. That's what I use. My 125L tubs were $20/ea (and I thought that was stiff). But hey, they even have wheels.

If you already have gnats in the rootmass, putting a barrier on will not help. Barriers must be installed before they have a chance to colonise, right after potting up is the time.

You now need an insecticide that kills the larvae. Order Gnatrol online if you have to, got to be many online hydro suppliers you could order from.

Get some yellow sticky card traps as well, this will help control the adult numbers to break their reproduction cycle.

well im gonna have 6 plants per 3x3 tray in 3.5 gallon square pots full of hydroton with just the rockwool kickin it.... so a 30 gal should be plenty?

[Eharmony420]

hey al, trying to decide what hydro system to use next. im using 4 pot bubbler and love it for this my first grow. i plan eight so maybe want something a little more complicated, maybe aeroponic or drip or flood. What do yu think, also i am using a 400 wat mh/hps can that do eight, curious

 

[Al B. Fuct]

Hey Al this is off the wall question about geting the ph down. YOu think lemon juice would work, are would I kill the plants?

I don't think it would kill the plant but you'd be introducing organic matter (fruit pulp) into the system, which could either induce or aid pathogen problems or would consume some of the H2O2 just by being dead organic matter in the system. Just use the right stuff, pHDown is the cheapest sauce in the hydro shop.

should I apply root powder on the cutting and plant it in soil?

Yep.

Also, with whatever one I do, should I foliar feed it?

Foliar feeding can be effective but if sprayed too often, plants can develop fungal probs.

If I add other things to the foliar feed mix such as fish emulsion, molasses, or some other vegging ferts, will this discourage or slow root growth / or how long it takes to grow them?

No, the roots will develop as they usually do. However, if your foliar feeding is successful, you might develop more foliar mass than the roots may be able to support.

If you're going to foliar feed with fish emulsion, I'm glad it's your place & not mine.

Keep several metres between molasses and any cannabis plant. Plants can not use sugars as a nutrient. Sugars are good food for insects and pathogens, useless to plants.

My pH had gotten too high (like 7.2) and it caused all kinds of funky stuff to happen!!!

Well spotted, thanks for making the suggestion.

Why so few plants and the huge pots? If you want to do SoG, your pots can be much smaller so you can get a lot more plants in. I have 23 x 175mm x 175mm pots in my 900x900mm trays, The tanks are 125L for each tray.

You want something MORE complicated? You obviously are not smoking enough dope.

Simpler is gooder. Tray based flood systems with pots of absorbent (RW, fytocell, perlite) or semiabsorbent (pellets) media are no brainers, can't clog, are flexible with plant numbers and beyond easy to maintain.

Media which supports frequent flooding allows more oxygenated nutes to be circulate through the roots, allowing productivity rivalling more complex methods.
