The yellow tips is from nutrient burn. Seems like you went just a little over with them but overall they look awsome.

Pretty normal for soiless grows. A lot of changes going into flower for the plants. I always end up with brown tips while growing soiless and so do all my friends grows..Never affects anything in my grows.?

Recommend ph 6.2 your in flowering. The straight burnt tips is potassium deficiency. Potassium is best absorbed in coco at 6.2 ph. 6.3 your plant will start going in lock out. Your run off ph is very important to monitor.

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀
