I'm about 7 weeks into a hydroponic grow. Growing 2 plants. My bottom leaves are turning yellowish brown, and getting brittle. Noticed some top leaves are slightly yellowed also. Growing using distilled water, so I'm thinking pH isn't the problem. Providing nutes for the plants, at a slightly lower rate than recommended to avoid nute burn. Its a 2 ft box, 3 100 W 2700K CFL flowering bulbs. Any hits/tips/suggestions would be greatly appreciated. Thanks in advance!
flowering? did you transplant? could be ph, root bound, deficiency We need all the info on your grow including: What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info? If any of these questions have already been answered please disregard as I cut and paste this for everyone. If there is leaf discoloration please TAKE PICTURES WITH ALL GROW LIGHTS OFF, ESPECIALLY HPS & LED's. Taking pictures and taking them with lights off, allows us to see what the leaf discoloration looks like.
