leaves turned yellow and brown

Hey I had similar symptoms in my white widow grow in week 9 and I got it fixed. I believe your girl is suffering from a combination of: - light burn (drooping leaves, only leaves closest to the lights are affected, yellow or burned tips) AND - Nitrogen deficiency -> leaves of the whole plant are looking rather pale green than dark green -> older growth is affected first (because nitrogen is mobile so it travels from older to newer growth leaving the older leaves with the deficiency) AND / OR - Potassium deficiency -> your girl requires a higher amount of potassium in flowering stage for bud development so there is a chance that the yellowing leaves are being caused by a potassium deficiency I would recommend to: - raise the grow lights - increase the amount of nitrogen that you are feeding your plant - increase potassium This is how I had treated my girl and she was cured after 5 days Also check the ph of your feedings as this could lead to locked up nutrients and therefore to deficiencies Hope this helps happy growing
