Too much light

Hey man, only a suggestion as I don't know all the details. If you wanna tell me more, drop me a line in PM. If you feel you have an overdose and possible lockout/semi lockout, a decent flush with 50-60% run-off at 6.5-ish pH soil, or 6.1/6.3 pH for soilless (not 100% sure what you've got going there...looks like Promix(?)). To keep from starving her, I've been told and have run a 1/2 to 3/4 dosing of 2-0-0 Calmag to replace and carry her until she's ready for another watering or feeding. Lastly, if the 50% RH is accurate, I would certainly bump this upwards. May be a reason why your girls are getting dry too, and they may not be taking in moisture at a high enough rate. Running up to 65% should yield a better atmosphere for optimal transpiration. Anywho! Hope this helps, but I may be off the mark depending on your other parameters or symptoms. I'm not in DOTM either.... screw that, lol! Please don't pick this as the answer if this is your answer. Cheers man👍
