First winter grow. Last summer my grow died in mid flower due to being away and had someone water them with inexperience and they drown them. Now its winter, I run dwc one is a auto (amnesia haze from cks) that shows signs of ph stress(only after I started to use ph down and set the nutrient water mix to 5.5, after the signs I stopped adjusting ph and will just use the AN con line with no ph adjustments)and what I believe is recovering from sulfur def after I added Epsom salt last night. I have already lost 1 plant due to nitrogen toxicity (royale queen seeds space queen) . My blue dream fem from HSO shows signs of nitrogen toxicity aswel but I backed off as soon as i saw. My problem now is the new growth is yellowing from the inside out, I dont think its N def as the leaves are kinda shineg and the tips were also yellowing hard to see in pic. I use the AN connoisseur line. I attempted to switch to GH flora series after my N toxicity but that has not done anything so I went back to AN last night. I flipped the lights to 12/12 three days ago as my blue dream is going to max out in height during stretch. Can anyone help with these deficiencies as the leaves almost look neon green and shiny, they are also curling/twisting. I recently riged a way to get the grow room at approx 70 deg with lights off as they were down to approx 61 degrees with lights off. Any help would greatly be appreciated as if this grow fails I will be giving up as it is to much $ on electric, nutes, time, etc...
