Stunted growth and yellowing not sure what to do...

[justice211]

so all of these where started at the exact same time and all other things equal also...ph 5.5 to 5.8 always try to keep it within this range with no major swings, light nutes as per feeding chart using gh flora nova and rapid start on after week one, they are now at day 11...also first two are in rockwool(smallest and yellowing) and the last 2 are in accel a root(one seems to be clawing)...not sure what to do here...any and all advice will be greatly appreciated before this gets worse...View attachment 60591View attachment 60592View attachment 60593View attachment 60594

the 2 in rockwool are in lockout... im guessing you didnt presoak the rockwool in ph 5.0 solution for 24 hours as per recommended?

your nutes are a little strong if you have clawing also...

in the chart notice how the rockwool being a high ph affects the visible nutrient deficiciencies...




I'd stick to the 5.8-5.9 ranger early on in hydro...

I did soak the rockwool but in 5.5 water and i will try to water the nutes down today on the one that has clawing...thanx for the advice
