Brown Tips

Hey man. You're in the endgame now The hard bit is done on N part Typically with the nutrients you needed to get that big. The amount needed now is much lower. You gotta change the nutrient ppm as the plant moves into a new phase. . Low dose ppm core npk nutrients during pre fower. Then you give more PK with some N but should be lower than you used for grow So, cut your feed. Lower your lights power, make sure your plant has good air flow around it. Higher PK is needed at this sage.. you aren't carrying the same ppm feed from your peak into now? If so that's your issue pal.

Your lady is burned at the top by too much fertilizer. The spikes can't be saved, but you can stop the problem! Just water the nutrients down a little the next time and the problem would disappear. Otherwise, your plant will look really good.👍🏻🏻

yeah like Organoman said, she might be overfed. but besides this, she looks like she is ready to get harvest soon?

Overfeeding and heat stress. Nothing hugely major, but try to reduce temps, make feed not so potent and increase air exchange.

Over fed/too much fertilizer.........nothing to do with "too much water".
