1st grow/ 17 gallon tote bubbleponics

I use rhizotonic the first 2 days. Then around day 4 will start giving them a small dose of nutes around 0.8 EC.

They'll be fine with ph'd water & calmag for a while. Theres nutrients stored in the cotyledons (those little rounded leaves you see). I usually start light nutes @ second set of true leaves or when those little cotyledons start to fade out. Goodluck!

I do Rhizotonic from the start and start giving nutrients after the first 7 days . I've found this works best to not burn the more sensitive ones

Yeah, they are growing as expected - looks super fine and healthy!

I'd hold off the notes till week 2 of veg but she looks great Good luck

Looks great the hard part is over. Only thing I'd say is those holes in the rapid rooter are big, I like to rip a corner off the side and fill the hole a bit

I wouldn't top an auto, prob do more harm than good especially if you are fairly new, I have only grown autos and am on my 3rd grow and I jus LST around weeks 3-4, and jus retie em down each day to keep the canopy as even as possible. Good luck, grow and learn.

Since it is an auto, don't top or fim, just a bit of LST once she is a bit bigger.

I topped my NL auto once in my last grow turned out great. I wouldnt do it more than once though not enought time to recover, i did it at the fifth node

Yeah look like a Calcium and Magnesium issue. Put some calmag in there and really make sure your Ph is balanced :) I could be wrong here but it looks like you might have some Nitrogen toxicity going on here as well. This looks like an easy recovery though 💪
