Leaf Edge/Tip Burning

Thanks for the responses. I've been feeding Terp Tea Bloom which is 3-7-4. I just ordered some Mega Crop Bloom Booster. We'll see how that does.

I'm not seeing any information on what, if any, nutes you're giving her. She needs to be on bloom nutes now with only a TRACE of nitrogen - so the P and K needs to be upped and the N reduced... This should solve your problem and give her what she needs. Lower leaves dying off? No worries... first of all, they're probably not getting much light and therefore not helping a whole lot with photosynthesis - your lady is quite bushy!! Personally, I would be trimming them anyway to try to get more air flow into the plant so no worries! Good luck! She looks good!!

Progress potassium deficiency is the problem. Your plant is trying to bulk and has a huge appetite right now for potassium and phosphorus, easy on nitrogen she is not using a lot now. Leaves at bottom falling off could be lack of light or she has gotten too dry. I imagine she is thirsty as well. Natural defoliation does happen on lower side due to no light. Good luck and happy growing. Brown and straight tips is potassium. Brown and curled up is nute burn. Happy growing 🌱
