Keeping it simple - Coco + Blumats

Kinda hard to see BUT, looks like an early Mg and some light Ca def.

As far as pHing hydro goes. Simply set the pH to 5.7 and let her rise to 6.2 and adjust back down... That zone is what "I" liked as my "safe" zone. Never had problems that way.

I see the new growth doesn't show that problem. That could be a somewhat common "blip in the road" growth issue. It ends to say that the problem passed.
Now IF it should come back, or increase. Add some Ca/Mg to your mix.
Thanks.

I’m using RO water now, and have brought my CalMag up to 5ml per gallon.

What's that Night Nurse like? I'm thinking of buying some seeds of that from these guys as I could use a good sedative type pot to cross with my CBD project. https://oldschoolba.com/old-school-shop/indica/night-nurse-seeds

You definitely get good results with those nutes tho I think the P is way too high in relation to the K in the Giant Bloom. Reverse that ratio and I think it would be better from all the research I've done and I do a lot of that.

As to claims of simplicity there isn't much simpler than a tub full of water with some basic nutes and an air pump. No water pumps, nute lines and all the connections to cause leaks or plug up. No holes below the water line in my tubs means no leaks ever and with the basic pH Perfect nutes I haven't tested pH in the last four years whether I'm growing in ProMix or DWC.

If you count the 3-part nutes as 3 bottles I use two others, Rhino Skin and Big Bud powder from AN. A little GrowTek Calmag and some Epsom salts is the grand total of my growing arsenal. People that buy the GrandMaster line and dump in everything eventually cut way back to the basics or just give up growing altogether but there's a sucker born every minute. :D

In about a month or so I'll have my new 8x4' grow space built with 4 tubs doing DWC ScroGs all set up and running. Got to get it done pretty quick as some clones are rooted and need a new home PDQ. :)

Wish I had the space @DesertHydro has for growing. I could fit a hell of a lot of tubs in there! I'd be going with RDWC tho if the wife let me take over the 17x34x10h work shop. Already grumbling about taking over the spare bedroom and making her find new homes for her junk. lol

Very nice grows!

:peace:
Well I'm reporting back on the Night Nurse. You definitely want to smoke it at night. Hence the name. It's couch lock pure and simple. It's been great with my insomnia. I'm very happy with the strain. It won't be my everyday weed but it will have it's times. Nighttime mostly. I'm definitely going to grow this again at some point but for now I have enough to last quite awhile. I highly recommend it.


I'm thinking of crossing a Candida 1 sativa pheno that I have with Night Nurse. I'll use the silver nitrate/sodium thiosulfate method to create male pollen from the Candida and pollinate a fem Night Nurse. I'm hoping for a high thc and cbd strain.

thanks for the report

ever smoke mk-ultra? supposed to be full on couch lock too. got a couple in flower now. just wondering how it compares to the night nurse...

Haven't tried MK-Ultra. But the description of it is appealing. G13 and OG Kush. I might have to give it a try one of these days.

You did the same thing I did but for a different reason. I hand watered my current grow mid flower for some dumb reason to about 20% runoff. Probably the single malt I had been drinking. But the result was not good. I thought that maybe I was getting a salt buildup so I hand watered with half strength nutes. Big mistake. I had nute burn symptoms the next day. Why I did what I did after three very successful grows in coco using blumats I don't know. I broke one of the cardinal rules. Don't fix what isn't broken.

I think the issue is that coco is able to hold and retain nutrients. When the moisture level is maintained by blumats those nutrients are able to stay in the coco and be used as the plants need them. If you disrupt that moisture level and add excess moisture to the point of runoff you break the bond between the coco and nutrients and release a nutrient flood causing nute burn. In fact I remember reading an article or two regarding that exact scenario. Minds smarter than mine might be able to elaborate on this but I'm just an IT guy and growing weed is a hobby. A fulfilling one but a hobby none the less.

I keep my pots feeling medium. Seems to work out.

Jacks should work well in coco. I think they use calcium nitrate for nitrogen so you'll not have any of the calcium issues people claim you'll have growing in coco. Vitagrow uses calcium nitrate and is used the entire grow so I never have calcium issues and don't use calmag.

Good luck with everything.
I'm on week 9 and thankfully I haven't messed anything up yet because I changed the res on mine a few times but haven't ran dripclean or flushed I've had no nute burn or anything until today, I went into my tent and 1 of the plants was really droopy and it was getting water idk what happened but I filled my res lst water run a little and now its standing better now

As always I am over thinking to catch any potential errors, hoping you or others can clear up some issues I have.

As I mentioned in the other topic I fear the risk of a full res dump. I figured it would be safer to use one smaller container/carrot per pot so that any dump out would be singular. The smaller containers would be around 5L each, enough to last 2 days. The elevation of the bottom of the containers above carrots will be limited to around 1 foot. The longest runs will be around 1.5/2m, will run directly angled to the pots with no dips in the lines as to not lose any pressure. I have a sneaky feeling though, that the height/water volume isn't going to give enough pressure when the water levels drop to 1L or less to activate the carrots. Can anybody with hands on experience with blumats chime in?.

My secondary concern is that although a bigger, aerated slave res will be used out side, the containers on the inside will not be aerated for the 2 day duration. However the small containers will be shaded so temp/ph and loss of oxygenation should not be to great over a 2 day period, until fresh nutes from the slave res are added.

I know it isn't optimal compared to a single large res, and ofc it's a little more work.. but ignore those factors please. Thnx for any input.

The only time I had water over flow is when I let the res go dry, if you do that you have to readjust the carrots but besides that i used them on my first grow with no problems and actually won 3rd place on newbie of the month and won free seeds but I just mean its really easy to use, I highly recommend them!!!

So am I mistaken to continually think that the carrot valve requires a certain amount of pressure to activate?, or maybe even to deactivate. Maybe the water in the elevated lines alone is enough pressure?. I've tried to find the technical sheet to answer this but no joy.

Or plainly put, if your hole is in the bottom of the container, would it completely empty?. Not that I want that to happen, but it just shows me that a low volume of nutes, say 1L , is still enough pressure to activate.

I put my res like 5ft above the pots and it was plenty of pressure, I think they say minimum 3ft above the pots and you should be good but honestly the easiest thing ever!!! And if there is anything I can help with let me know, I only have 2 grows in but the blumats were do all the work just make sure to get all of the air bubbles out of them and dont let the resivoir run dry and you will be good, it took me about 20min to get the carrots dialed in and after that they basically let you know when they need to be adjusted for more water flow

Not the best pics but a little look into my setup

the carrots are not pressure operated, they shrink when dry which allows the water to flow, then when they are wet they expand to close the water flow, you only need height or a small amount of water pressure so there is a flow through to your drippers

They said the res needs to be above the pots because they need some pressure to get the water to the carrots, gravity is enough, then they do the rest.

yeah...the carrots themselves are NOT pressure activated, though of course water does not run uphill and therefore a res higher than the pot height is needed, but it can be a few feet above is all that's necessary

Ah ok, that's the info I was looking for. As said I don't have a few foot height to play with given the container location, only 1 foot. But if the carrots work just like a free flow pipe then that's fine as I've been using the same singular res setup only with custom halo drip hoses. They do the watering slowly over an hour period or so.. but they won't keep a constant moisture level over the days like blumats, with obvious added bonus.

Would you say the volume of water is sufficient for every other day fill ups (roughly 3 gal pots). I read they use less water with blumats so hopefully. Also any concern of the 5L volumes sitting over the 2 day duration?. they will completely out of light and direct heat.

i guess your 5L volumes would be ok for that period and not go off though maybe have to test the PH every day, cannot see why not? i can't comment if that volume would be sufficient for any period of time as each setup needs individual tweaking, then when its all dialed in you can take whatever time is allowed out, just have to watch closely until you have it worked out, my next Blumat setup will be the long carrot type(6") inserted into the lower side of 30 gal fabric pots with the spaghetti tubing going up the side to the top with 5 drippers situated around the top, should be fun trying to dial that setup in cos the pots will be too heavy to lift, which was the main way i use to test if the pots need watering or not
