I'm in my last week of vegetation and swapping to the flowering stage this afternoon, but my leaves have started turning yellow on a few of my plants. I've been using a DWC setup with 5 gal buckets filled with tap water(ppm 250) and Advanced Nutrients Sensi Grow A & B, Botanicare CalMag+, and Nutrilife H202. After adding the nutes the ppm is reading 985, which would actually be a ppm of 735 right?(I subtracted the original ppm of the tap water from that reading with the nutes) Correct me if I'm wrong with that. Also, I buffered the solution to 5.6 pH. I noticed the yellowing of the leaves a couple of days ago, and decided that I would try adding a little more Grow and CalMag+. It's only been a few days, but I haven't seen any improvement. The leaves are still pale green and yellow with the veins dark green. Any suggestions? Should I add even more of something? Maybe I'm missing something? I'm a first timer with hydroponics, so I don't wanna lose my crop!
