Check this out, My plant is looking really healthy, no problems. Its in 8 gallon pot under 1000 Watts HPS,12 hr cycle, start of fifth week. Foxfarms Happy frog dirt. It was doing great, nice bud development at this stage. Suddenly leaves are turning yellow with little spots that are converging into spots. Does this look like PH Problem? I use Advanced Nutrients Ferts, A+B, B-52, Mother Earth Tea bloom, Carb Load and Big Bud Liquid. Also I adjust my well water with PH down. Check pics and let me know what you think. Greenfrog
Spider mites! I can see 3 on the last pix. Get a no pest strip or neem oil or fogger. kill them now... alex
Monday morn, I sprayed neem oil on the plant twice in three days and cleaned the room and sprayed it. I also put the plant in the sun for three hours of its 12 hr cycle for five days now. It looks like it is greening right up. I found little black spots on the bottom of the leaves. They wiped off so I am assuming they are some kind of bug. I will keep up a regimen of spraying every week or more as needed. Greenfrog
