do as seedynono sez. don't know what your feeding them, but whatever it is lightly is best since they are small at this point.
if the ph gets corrected and they continue to get lighter in color leaning towards yellow you might want to feed a little more.
but don't worry or try to "fix" things overnight.
it takes a few days (4-7) to see results of correction.
after ph is corrected they will be able take in nutes more efficiently.
then if you still have concerns chime back in.
peace.

oops i guess you posted while i was writing.
........nevermind.

Bottom photo looks like the stem is getting a fungal canker. The stem is brown/black. Looks like its even wet = disease problems
I think the yellowing is a case of zinc deficiency:
Reasons for zinc deficiency:
Obvious solution is the plants need fert with micros containing zinc
Other reasons:
>too wet
>too cold
>too much phosphorus
>too much alkaline earth metals especially magnesium; too much dol. lime or cal mag or both
>too much copper
>too much iron
>ph too high
>rootbound

Nice to see and hear that you really are thorough. That particular plant with the blackish on the stem is a bit older than the pic( like a week or so) and the black is completely gone, and it's my fastest growing of 6 White Widows.
I need to find a good mother. You find White Widow to be a nice strain?
The curled leaf might be a bit curled. What is that?

Yellowing between the veins and curled margins like that probably zinc deficiency. If there is zinc in your ferts, check the other possible things on that list that might be causing problems. Lack of root growth possibly. That bottom picture has alot of redish-purple color. Maybe phosphorus deficient? That would also go along with reduced root growth. But also ph could be a factor. Aim for 6 ph in your fert water after mixing. Temperature too low?

Tx for the great links there, Sproutco. Looks like you know what you're talking about. This is an amazing way of growing weed. Although it seems more natural to have the plants in the garden in soil, this rocwool thing is just much more controllable and i fell in better contact with the plants.
My plan is to clone the 8 plants i have here in their 8 weeks of growing and put the original "mother plants" into the flower tray which is 130x100cm with a ebb and flow and a 600w hps. After finished flowering i plan to find the most potent and tasty plant and clone that. i was thinking of maybe make a sog in this tray with maybe 20 small plants. Does this sound reasonable? Or could the tray be bigger for this 600w lamp?
Tx again

I have 10 WW going from Seed. Out of 10, 8 Female and 2 Male. Of the 8 Female, only one is short and bushy. They were 12-15" tall when I switched 12/12. The first two weeks of 12/12 7 of 8 streched BIG Time. They are 23 days 12/12 now and are 40+ inches tall. The one short girl is by far a keeper (if I was going to keep a mother)
I just put them under 1000w HPS from 400w due to the MASS WW jungle

Tx again, Sproutco for helping out. Some more of my plants are showing a small sign of this ???Zinc def.??? Few leaves with these signs also curly their leaves slightly. I'd really like to get this gone.
Ph: 6 (adjustet every day, sometimes more than ones)
Temp: 20c
Humidity: 50 ish
Grodan 3"x3" in pots with small leca rocks.
Water in ebb flow manually about 3 times daily. (maybe this is too much. Just figured it would be allright with rocwool and small leca rocks)
But i'm using these fertilizers dozed excactly as described on bottle. Shouldn't they also get the Zinc they need from this?:
Pleas help me more, if these details help a bit more.
Sproutco?
The blackish on this stem was some kind of dry peal that just came right of.
This plant is beautiful i think
