Hey guys, thanks for the help.. I've been watering a lot less and it seems to be helping, under the 24 hours they dried out a lot quicker than being on 12/12. But they still dry out pretty quickly. I'm using fox farms soil and I have given them 2 feedings of tiger bloom so far, but only a 1/2 dosage, and I use big bloom supplement like every other day with my watering. PH of water is 6.4, not sure what my soil is

I figured it might be the manganese so I gave them epsom salt but I don't know if that really did anything, the veins turn brown as well.. Seems to start fromt he bottom leaves and moves its way up. I just turned on my lights now for 12 hours of light, and finally the 2 struggling girls are starting to bud, so I'm taking that as a good sign and i'm going to change up the way I water a bit to dry them out more.. They get dried out very quickly though beacuse I live in the desert, thats why I've been watering them with like 36-48 ounces everyday.. Hoping this is the problem i guess, just worried that it might not be, I didn't think overwatering would have this type of effect.. maybe its overwatering + a toxicity / nute burn ?
