I was told this is light doing this. Only grow it’s ever happened in. Water pH is at 6.2, EC is at 2.2. Feeding Jacks Nutrients 321 mix. Mixing correctly with no other additives. I have never changed the lights,so I’m just not sure it’s that. Par is reading at 350 in veg and 500 in flower. I’ve looked some things up saying it’s cal,mag,and potassium deficiency,not light burn. Or it’s one making the other susceptible to it. All new fan leaves are skinny as all hell and some new saplings are starting to lose color. Also seems like there’s very little root structure,like they are all very thin and flimsy down low. Gonna try to add the supplemental calmag and some extra potassium and see. All else has failed. I also switched to Vic to see if that works. Here’s some pics...
