Should I be worried? 2 1/2 weeks from harvest

2 1/2 weeks from harvest, start flushing and forgettaboutit

Hi there Vegas_Kind_Budz! Yellowing during the last weeks of flowering are expected, as the plants take all remaining Nitrogen resident on plant matter, while still uptaking Potassium and Phosforus. Depending on vegetative/flowering feeding schedules, and also strain, they will get yellower early or not at all. That's not a bad sign, but I won't recommend to add any kind of heavy Nitrogen nutrient now, just the bare minimum and keep the P/K feeds as planned. This is the same as tomatoes/peppers/eggplants, if you feed lots of N, you will have huge and really good looking leaves, but you actually want flowers (or fruits). Keep on the great care and let us know here or by private if you need anything else! Happy smokes!
