All my fan leaves are dying week 3.5 flower

thanks for all the responses guys, sorry i was at school all day so i wasnt able to join in. But, i will start regular feeds tonight and pick up some epsom salt this weekend. i have alright drainage and some seepage usually but ill make sure to work on that too by removing part of the bottom of the pot (it catches runoff and keeps it in the bottom of the pot). Ive heard that low humidity is good in flower though, to cut the chance of mold and produce THC. isnt 35-50% optimal

John,

That's a good idea. You should never let any container grown plant sit in standing water. Besides having drilled numerous extra drain holes in the bottom of my pots I also keep them blocked up a half inch off of the surface they sit on so that not only can they drip out freely after I water but also so that air can circulate up under the pot. Since you only have a small number of plants going I'd recomend that you water by sitting them in the sink (or tub) and then use enough water to where you get a good amount of run off out the bottom. Then let them sit there for 15 to 20 minutes so the soil can drip out all it wants to before putting them back on the base they normaly set in under the light.

Concerning MG ferts burning roots.....while there's no doubt that a lot of people have fucked up a lot of pot plants using MG products the fault doesn't lie with the MG products themselves. You can fuck up a plant with any of these ferts that are out there if you don't use them correctly.

That MG tomato food (18-18-21) you've got wouldn't be my first choice for a supplimental fertilizer but since it's what you've got on hand I'd recomend you give them a dose of it. I certainly wouldn't run out at this point and spend a bunch of money on one of these wazoo cannabis specific "bloom nutes" in hopes that it will somehow magically fix your plants. It's just not going to happen. The damage has been done so to speak and nothing you can do at this point is going to restore those fan leaves. The best you can hope for at this point is to slow down the rest of the plants foliage yellowing out an dying so that you can get some smoke off of it.

I've been using Jack's Clasic All Purpose Plant Food (20-20-20) this grow (for both veg and bloom) with pretty dam good results. I'm about a week or so from harvest and still have 90% + of all my foliage in a good healthy green condition. And I'm using the original MG potting soil as my growing medium. The only thing I've ammended it with is about 20% extra perlite to improve it's drainage characteristics.

As to humidity.... I wouldn't get caught up in fretting about it. I don't think it has any bearing on what's wrong with your plants. If it's in the 25 to 75% range you're fine. If it get's above that for extended periods of time you might have to start worrying about mold problems. I never view low humidity as a problem. It just means you'll have to water more often.

Im using bio-bloom and green sensation at the moment and think i need to increase the N intake, is there anything on the market that can provide just that? Or can upping the nutes help?

its 9 bubbleberry clones under a 600w light, soil grow, good temps, in week 5 of flower...

Garden,

What are the NPK numbers of the "bio-bloom" and "green sensation" you mention? It's been my experience that you've got to be real careful in using to many different products during a grow because in an attempt to get a little more of one thing you can easily get to much of another. For instance, if both of those products you're using all ready have a lot of P (phosphorus) in them, upping there dosage to try and get the plant more Nitrogen is a bad idea. To much Phosphorus will cause a "lock out" of some of the other things a plant needs.

If you're sure that your plants actually do need just a little more Nitrogen I'd recomend Alaskan Fish Fertilizer (5-1-1) as a good source of it.

Jack

Your plants need foood dude

Thanks jack,
Ive begun feeding them now, just wondering:

How often should i be feeding them? Every time i water, once a week or what?

Thanks for all the help guys, glad i posted here
Im not to bummed out about the grow, i think i should be able to pull 3 ounces off of the 5 plants which is better than nothing.
At this point im just hoping for some dense quality buds

my container says once a week so i will go with that
thanks again guys

John,

You're welcome. And I wouldn't get to carried a way with feeding them or you'll end up with the opposite problem of fert burn'n them. I'd stick with what the label on the package recomends.

And I hate to be the bearer of bad news but, if the plant you posted a picture of is representative of the other 4 you have I'd be surprised if you got 2 oz. of dried bud from them. All those fan leaves you lost are basically where the plant does most of it's photosynthesis and gets it's energy to grow. I hope I'm wrong about this prediction, it's just in the past I've seriously over estimated how much yield I was going to get off of plants and then ended up disapointed. Now matter what you get I'd take the attitude that you done good for your first time because you learned a bunch that will make your next attempt at it much better.

One other suggestion...get rid of that layer of sand you've got on top of the soil to try and control the fungus nats. It seriously interfers with the soils "breathing". I tried that same thing a couple of years back and I'll never do it again. In fact once you've got it off of there I'd recomend you take a dinner fork and till up the top 1" layer of soil so it was loose. I do this a couple of times during a grow just because of how repeated waterings tend to compact the soil surface.

A couple of fungus nats in your grow isn't going to really hurt any thing. I always seem to have some. To keep them from getting to numerous I always set out some of those yellow sticky traps on stakes stuck into the soil from the very beginning of a grow. If you can catch most of the first ones to emerge and keep them from reproducing they won't get to out of control. If they're already seriously out of control you can put 1/2 tsp. of 50% Malathion in a quart of water and spray the soil surface (where they live and breed) with that. I've also used that mix to control an out break of thrips I had during veg a couple of grows back with great success. Of course to treat for thrips you've got to spray all the foliage and I wouldn't do that very far into flowering because of getting it on the buds.

Hey, I'm havingva similar problem. Most of my fan leaves are turning yellow and dying. I haven't seen any amber pistols yet but most of pistols are browning or turning orange... I'm finishing up week 9 on Saturday. Idk what's going on... Can someone tell me if its almost time? Buds don't look very big but lots of trichomes. Can anyone tell by looking at them if they're ready?? Any help appreciated...peace

well my last plant had a lot of issues... But this one I got going now seems to be doing good, I do see I knat or two flying around now and then, I think I got rid of the arva though with that 'mosquito dunk' stuff. I'm going on week 7 . a lot of my leaves are curling under and kind of yellow. Is that normal? This is only my second grow, so I'm still trying to figure things out. I'll put a few pics , how much longer ya think she has?? Oh by the way she's rootbound.. Think I should transplant? Appreciate any advice. Peace.

Have you checked the pH of your runoff? Your girls aren't feeding for some reason. This could be the problem. Had a similar issue. Good luck.

they look hungry bruh, to which end I imagine all your problems are relative.

Just my opinion but...6 inches from that 400 watt HPS is kinda close? I can't believe your not scorching the tops

Lol, they're more like 18" ufrom the light! Should I still raise it a couple inches?

Please explain how you got a plant to grow straight up without a single side shoot? That's amazing! I'd really like to know.

I just had this same issue. I had 1.5-2 inches of sand on top of my soil. My plants weren't able to breathe. The sand had turned to concrete. I scooped off all of the sand and replaced with soil. They had almost died, but I think they will be ok now.

My camera isn't the best but there are many shoots on that plant

yay ... I hope mine makes it..only has a couple more weeks... Too late to repot.. Hoping for the best... Oh I'm attaching a pic... The "plant" ur referring to having no shoots IS actually a shoot...lmao

er, might be a bit late to start feeding

. That's what I was thinking.... The buds are very dense, pretty nice size... I'm just hoping it makes it a couple more weeks in that pot.....peace

Check the EC of your run off, if it is higher than you are feeding at then they are being over fed or have a pH lockout and need to be flushed. They look like they aren't getting enough Nitrogen and the plant is pulling it from the leaves.

youl be right next time bro
