LEAVES dying. Cause???

if u are using soil, start ur feeding after the plant has 2 or 3 sets of leaves, a small plant cant stand extra feeding in big dosages

To much watering or RH to high aswell or last but not least nute burn. Just let her sit for a couple of days with no watering and she should bounce back no time. Best of luck to you 👍

I think it could be too much food, i normally don't give any food the first 2 weeks as the soil has already enough food for the first weeks (depends on the soil of course)

I think overwatering and night temp is pretty low

Looking like the tips are burnt. If you plan on using Liquid nutrients in your grow its bet to use a TDS Pen to measure the concentration or EC - Electrical Conductivity of the solution. Autos Like less feed vs photos if you useing a feeding chart. they can take 1/3 to 1/2 strengths. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ Good Luck!
