Have 48 of these girls in this current run, all healthy prior to transplant from 1 gallon to 7 gallon. Within a week about half the garden showing signs of the attached photos.
Thinking its Phosphorus deficiency, anyone can confirm or offer up any other thoughts?

Plants are hungry! That is an N deficiency. The plants (FYI) consume very little P or K at this point in life. Are these clones?

What the heck is this?!

How high a PPF are you running? Over 1,500 µmol/m2/sec is necessary to make use of CO2 FYI. Not sure one light is enough for flower.

Media looks awfully damp too (understand you could have just watered).

Yes they are clones cut from the mom in our veg room. These girls are about 11 weeks old from dome to 7 gallon pots. 1200 PPF on the CO2. This pic was taken just after feeding, Drain to waist system, currently hand feeding until they need day to day, once we hit that point we install the feeding system.

Well I’d bump up the N for sure. @TDubWilly has done CO2.
