whats up everyone, im trying to figure out whats going on with one of my plants. I have 2 NL plants flowering in a 2'x2' mega garden hydro flood and drain system. its in a closet that's about 4' by 8' and about 8' tall. I have 1300 watts of HPS on them lol 1000 watt at the top and 2 150 watt at the bottom. one of the plants has a bunch of the sun leaves that are yellow and some that have died.. ive done a lot of research on finding out hwats going on but I have one plant looking amazing and one that's not doing good that are getting the same nutrients and same light.. the one not doing so good was more centered under the light so could it mabe have gotten so much light it was starving for nitrogen or something? my temps are great, great air flow, kept my ph on constant monitoring and within 5.7-6.4 and from 800 ppm up to 1000 ppm fert and also just started dosing calcium and magnesium. any ideas? the roots are still growing really fast and healthy and the plants are about 3' tall. also the yellow leaves are only in the bottom half of the plant the top half is nice a green I just don't want it to creep up higher haha
