Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Plant #1 is showing some leaf discolouration. Not sure if it is nutrient burn/lockout or deficiency. I flushed her with R.O water just in case. Any ideas or suggestions? She's an odd one anyway, seems to be a different phenotype than her sisters.

Nutrient Deficiency
Is this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.

Phosphorus Issue?
Slurricane is having a phosphorus issue and not drinking water as fast after transplanting. I’ve been feeding cal mag every water and thinking it’s a root zone issue. Should I apply stop watering and apply a follar feed of 3 part general hydro nutrients?

Discoloration???
Noticing slight discoloration on Gelato, running in living soil, does this still have something to do with a nutrient deficiency? Has anyone encountered something like this?
