this is my first grow.. im using fluorescent tube and Mh light. I grew from clones and its been on 18 hours of light for 8 weeks now. about 3 weeks ago my leaves are turning yellow from bottom to top. some leaves look like lime green an some dark green. today look like some of my leaeve on top are having dry spots (dead). Also some of my eaves are having little brown spots on it. I want to flower my plants now but should i wait cuz I dont know if i over water it. I water once a day giving about a cup or two. I havent been on top on my nutes, I skipped a lot. I was using the fox farm thing. I will try to upload some image soon, right now i cant seem to upload to the site.
