Tell us more about your grow, what has you worried? If those tips get more brown and crispy, or start pointing down at an angle, back off on the nutes.

thanks for your reply.I haven’t seen any marijuana plants before, and I thought black leaves are bad. I bought 5 runtz auto flower seeds for fun. And I want to smoke my own weed.ppm 750, ph 6.1. Recently I see a few spider mites only a few and the leaves edge are turning black. So I come and ask for some help

Uh I wouldn't call that flowering yet... She looks good to me.

She looks normal. Nice green to me but keep checking in case.
