FIRST ATTEMPT

I really don't think you have anything to worry about, my last grow I had 1 plant have strange blemishes on the 1st 2 sets of true leaves and after that she was fine.

I don't see anything to be worried about here... the only thing I would say is that they look pretty dry. You need to water out to the drip line (the very end of the leaves) .... you need to encourage the roots to expand out and down so water sufficiently to do that - if roots hit dry soil, they essentially stop growing. Just let the pots dry out between waterings as overwatering (the state of being constantly wet) is a danger you want to avoid. Good luck! They're looking quite good!

Over feeding.........bloom mix is for.........blooming. Autos can usually get by just fine with half strength fertilizers, especiallly when growing in soil. Baby plants need baby feeding. Also, for the sake of your plants, please go to 18/6 and give them the sleep that they NEED to be able to finish their daily photosynthesis cycle and have a correctly functioning metabolism. A plant with an incorrectly functioning metabolism will NEVER grow to its best potential. Nothing on planet Earth can survive for weeks/months without sleep without causing massive problems. The MYTH that it is ok to grow cannabis at 24/0 needs to be removed from history asap! Google "plants and circadian rhythms" for further information. Besides, cannabis, autos included, can only grow so much during any one 24 hour period and this growth tops out at around the 18 hour mark, meaning running your lights longer than 18 hours is basically a waste of electricity. Since you are growing organically, I guess you care about your plants more than most, so why push them at a million miles per hour with continuous lighting and no rest ever?

Watch your light height but it looks fine to me 💯👊🏻
