It's D25 and things are not looking too promising. I swapped new solution this monday with ~340 PPM (plain water 80, enzhymes included. last week was 290). It might be mostly just sludge/colour from solution but definitely seems like there might be some pythium issue going on at the start of roots. I'm not gonna do anything radical to it like peroxide. I topped the bucket with fresh, diluted and chilled solution and we'll find out in couple days if we still have growing plant left. Lower leaves got some nasty looking brown smudges started. I've kept PH somewhat well at range so I dunno, maby it's just good old nitrogen od?

Plant still looks somewhat healthy and willing to go so maby I'm able to start bending it in couple days. Anyone in the audience with similar experiences?

d2&: roots situation seems to be getting better and ph is suddenly keeping itself stable. I was hoping the plant would stretch a bit more but it really wants to keep it bushy and compact. Gonna be fun time bending the small trunk thats getting wider and wider :)

Grow Questions
haftanara week 4 started grow question 3 years ago
I know there might be millions things causing these but maby this is some common problem with hydro? Do things like this usually come along with root problems or have i messed up some other obvious thing? Other details in weekly/pics

hi there Haftanara, i can confirm that it's surely not N toxicity which you can from dark green leaves and glossy shine. It's not calcium problems which are more "spotty" and it's not magnesium which is more uniform around the edges of the leaves. It's could be PH fluctuations , certainly it looks exactly like it, but what i do think it is, is root problems that look like pH fluctuations because we're also seeing that leaf cupping and leaf curling ... and, you know... brown roots ! so what you can do is get something like some hydroguard, up the enzymes a lot maybe up to 2 , 2.5... or what i think will help the most is a technique called root pruning. Root pruning is when you cut all the unhealthy roots off, carefully. This technique is very effective at stimulating growth, so you'll actually see faster and more vigorous growth ! what you do is simply cut off any brown dark brown roots, until there are none left or until a maximum of less than 20% of the total root mass... then wait and see how great it helps ! you can repeat this once a week once every 10 days, up to you and up to the plant, but you wont be stunting it's growth, on the contrary, the plant will thank you for it ! does this make sense ? hope this helps ! :rocket:

There's some purple hue thing going on, think thats another nitrogen / ph lockout kinda thing, pheno or is this the kind thing to happen when you keep temps sub 25C? I did give it fairly sturdy bloom and perhaps little too much micro hence the burns

Looks like its normal i just would wait and maybe lower the ph a bit (5.5 - 5,8ph) . Some strains get/are purple/viloet/red/black or whatever (ww not really :sweat_smile:). In the other hand plants turn purple at flower stage if the night temps drop (depends on strain how low, but in my experience normaly at about 15C° and strain which like it warm already starts sometimes at 20C°. Your PH can you geh down with a good ph down product. Take water, check ph, add ph down if necessary and mix it, wait some time and check ph again. Do it till your ph fits. (Ps the wait Time after adding ph down befor checking ph is important, so everything geh really mixed.) I use lemon juice to get my ph down, but im growing on soil and i dont know if lemon juice keep the ph stabil with hydro. Good luck :v:
