Hey buddy the Ph should go down to 5.5 - 5.8 at Hydro. This may fix your problem. I find the Ec value a little high with such a small plant :-) but only my opinion :-). Do they give Cal / Mag extra? when Yes, how much ?

Hello.. Hope you are well.. T h if ur other plants aren't affected and they have all had exactly same conditions then it is either.. Just a genetic flaw in her.. Or, she has slightly different needs than ur other strains e.g..less/more watering/feeding.. Different ph ranges.. If u did her again and changed these parameters she wud most likely react differently.. Its alot of trail and error tbf.. Stay safe n gud luck on future gardens.. 👍🍀

Early flower leaf oddity Noticed odd markings on leaves, some top or mid canopy some below. They vary also - from heat stress, shiny spots, residue from Insecticidal soap or wind burn in odd spots. I’m about 2 weeks in flowering. Temp was 27 degrees, had to defoliate massive fan leaves... see b4/after

Should I wait for deficiencies to introduce more nutrients? I haven't given these plants any of the A.N. veg nutrients that I have for them. We are at week four today. Maybe there are deficiencies that someone could point out to me from my photos?
