Need help!! Hydro (pics inside)

They in large rockwool cubes? How often you flood?

Looks like they are drowning to me. Cubes that size, they only need flooding once a day max, prob every day and a half. Either that or lower the flood level so the flood dont reach the rockwool.

Fresh transplant plus high nutrients would bemy guess. Its very hard to overwater rockwool so I would look at the transplant as the culprit. Flush them bad girls real good with bamanced water then use 1/4 strength nutes until you see them perk back up.

you say you are using tap water but you haven't mention what your PH levels are.

i believe without the right PH, Nutes are pointless

from the pics it looks like a mag lockout this is due to not having the right PH if you dont act fast your plant will turn brown stop growing and die.

if the hydro shop is to far, go to a chemist and buy a bottle of espon salts


i hope this helps

Tough choice OP. 2 contradicting bits of advice.

Another cause maybe change of light source, judging by the reflection on ya foils (bin them by the way) You are using cfl's. Were their old home using HPS?
They don't look nute OD'd to me, what is you EC (PPM) and PH??

I would not put those ladies in to flower yet, unhealthy plants do not produce well.

You need to fix your pH and E.C. There is no need for them to be out of the range you desire, this is what hydroponic growing is all about; control.

Rockwool saturation is a real problem, many growers think you cannot over water rockwoll then are constantly battling mold and fungus issues.

Large rockwool cubes need flodding only once possibly twice evey 24-48 hours, any more and your gonna be depriving oxygen.

regards,

My ph stays at 5.7 5.8 but my ppm is close to 1800 and they only have been getting feed once a day for the last 4 days I thought maybe under watering but then again they were just moved and changed lights

The cubes are only 3 inch cubes and I've only been watering once a day for the past for days and they start falling and turning yellow a little bit I just put them under 1000w I believe they were under cfls before

I think your right ima going to do that tonight
