Hey guys, I'm having some trouble with my seedlings. This is my first hydroponic grow so advice and constructive criticism is more than welcome! I tested the pH this morning and noticed it was 7.2, when it should be in the range of 5.5 - 6.5. I purchased some pH up and down and adjusted the pH (5.8 ) before watering this morning. Hopefully this was the problem that's causing the discoloration in the leaves due to nutrient lockout, but i'm only speculating.
Before anyone grills me for using a 600W HPS for seedlings, it's all I had laying around and I'm broke from buying university textbooks.
