HELP please! What is going on here? Spots and light edges

Hi everyone.
Posting because my google searching isn’t cutting it. I’m a new grower and am on my first indoor grow.
One plant’s doing fine and my northern lights auto sweetie is struggling. The lower first true leaves have brown spots, a wave, and are getting crispy, the first fingered leaves have some lighter green edges and is now getting brown spots there too. New, small leaves are okay thus far but I’m starting to convince myself the edges there are lighter too. I know I’ve been overwatering so I’m now trying to pull back on that. Using living soil comprised of peat, compost and perlite/rice hulls and a little build a soil craft blend. Only feeding so far was a tablespoon chicken manure and a tablespoon build a soil craft blend (both top dressed). Am watering with some mycos, aloe, and honey/molasses mixed in with tap water. Temps are 75-80 or so (give or take) and humidity is on the low side because of the space I’m using . 40-50 or so RH. Using a 300 watt viparspectra light at 50% currently and par is around 500. Plants about 13 days old and right now I’m doing 24/0 lighting but will prolly switch to 20/4 when the timer I ordered gets here this weekend. I know tue plant looks shitty and I’m kinda embarrassing honestly but I need the help to try to get through this grow and to avoid mistakes in the future. Thanks for any help!

Looks like Nitrogen Burn Or a cal-mag deficency to me, but I am far from an expert, I would water with some plain pH adjusted water with some Cal mag in it, unless you have watered recently.

I should have added that I was having some fungus gnat issues too and was REALLY overwatering….trying to rein both in but could the presented issues be related to either of those?

You may have diluted the Cal Mag in the soil. Not real sure tho. But hitting it with some cal mag cant hurt.

That looks funky, like an infection. Overwatering and gnat larvae will both hurt your roots, and you can get something bacterial/fungal from the ensuing rot. If you built a decent organic soil and let it cook, you should have enough food in there at this stage. I’d consider something like a compost tea to help your microbes. If you have something bad going on at the microscopic level, there’s a possibility that they might take care of it. They do most of the heavy work In organic. It won’t hurt.

Thanks for the input both of you.

I’m not super set up for compost tea but I have compost, so I’ll plan to top dress with compost before next watering (trying to dry out right now) and then I’ll see what happens. Hoping it’s salvageable. I don’t have cal mag stuff but I think (read: hope) the soil i built and the craft blend i top dressed with would rule out deficiencies (but I have no idea obviously).

maybe I’ll water with some mega crop when I water in the compost…I’m pretty sure mega crop does a decent job including cal mag in its formula.

Your just splashing to much. You can probably knock a ¼ strength off your feed. I see bleaching in new tip growth, but the bottom leaves r getting splashed when you water and they don't like all that nutrient solution on them.

I haven’t used liquid nutes yet…but I have watered with the aloe, honey/molasses, mycos in water. Could that on the leaves cause this or do you mean the top dressed nutes are getting splashed up when I water them in? Thanks for the reply! The other plant has gotten the same treatment but looks fine…dunno

Shoot should have asked before but what does the bleaching in new tips mean? I think that’s how this junk looked at first on the lower leaves
