Sorry about being too vague. My plants are in flower, i currently water once a day 15 minute flow in ebb an flow in a 4 by 2 grow tray. My plants are about 20 inches tall and are in 4 inch rockwool cubes that are surrounded by hydroton clay rocks.400W HPS. I keep my PH around 5.8 to 6.0. my temperature is a little low in my bud room. Around 45-50 degrees. Humidity i am not sure but i do have a outtake fan. The only nutrient i use is Maxibloom, i put 4 tsp in my 20 gallon reservoir. I only put about 6 gallons of tap water in the resevour because it is all i need. I am going to start watering up to 3 times a day once the roots expand a little more. I feel as if the rock wool soaks up too much water. After reading this does anyone know what these brown spots are? I am desperate to fix it and help my ladies grow as healthy as possible.
J-dubb206 Reviewed by J-dubb206 on . Brown spots all over flowering leaves, NOT BUGS All 4 of my plants in my flower room are all getting brown spots all over the leaves. I have done countless research and have might of came to a conclusion. Nitrogen or calcium deficiency. I do not know this for sure so in that case i would like some back up. If it is how can i fix it? I need a second opinion of diagnosis before i go about treating it. Thank you Rating: 5
