The tips are painted. Good uptake. Possible high N with the dark green. I would add some epsom if havent. 1 tblspn or so top dressed in. Looks like she craves some with the leaf fade between the veins. Just what i can see from here. Epsom wont hurt a thing used moderately. My thoughts but younger better eyes will chime in. Too young and too healthy for a major issue.

Thanks everyone for taking the time to look and advice. I top fed some epson salt so see how they enjoy that. Ive just never had anything pop up this early. Ive always just leaned on the nutes in the FFOF for first month of growth.

If growing in autopots top dressing isn’t very effective because they are bottom watered so water soaks upwards through the media pushing everything to the top layer.
It’s totally backwards then normal.
If no experience with soil in autopots but i grow in autopots useing coco-coir with synthetic nutrients.
With soil they could maybe top feed the magnesium with out issues but if i pour anything in the top of coco-coir in autopots, it pushes the nutrients thats built up top down into the root zone and throw tds and ph all out of wack…
But that’s coco useing synthetics, I’ve really no idea about soil in autopots honestly

Thanks man. Makes total sense.
Yeah I usually dont top feed anything with the autopot system. mainly because of salt buildup. figured id give it a try this time since I havent started any nutes thru the system yet. ill probably start adding some cal mag now thou.
