This is the main cola on my Blue Mystic. It appears to be yellowing from the center of the leaf outwards, veins still green. A little background info: Week 3 of flower, 5 gal DWC, 600w cooltube, tent temps 73-77, Ph 5.8-6.2, Res temp 73 (too high i know, adjusted temps earlier today), Using Fox Farms trio at half strength, EC at 1.2. The light was pretty close to top of the plant so i raised it about 10'' from top. Does this look like a deficiency, light too close or what?? Should i up to full strength nutrients? i want to solve this now before it gets worse. Thanks for the input
