New Grower

I agree with the others on this, 3 weeks easily. Just ph water with maybe a root stimulator.

If you're running LED lighting, why is it 27" above the plant? Try reducing this to 18". Otherwise, just give her some time to grow, you'll be surprised how fast things can move.

I like to follow this grow guide for feeding autos. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ Note that autos do not like as much feeding as a photoperiod does. Given the soil should be good for the first few months this should be ok for that time, unless you see it acting up.
