Sick babies in faux-mix

I'm trying to grow in peat for the first time. I'm using about 40% perlite and some lime for PH. The temps have been around 73-75F with RH at 55-60.
I have been fertigating with jacks 321 as if it were coco just due to all around ignorance regarding the medium (both tbh). Feeding daily or every other day with plenty of runoff.

The larger plant I am mainlining and is about 2 weeks ahead of the small ones. It is bagseed. It's sitting at 1200 EC right now. 30 days from seed.

The smallest plant is peyote gorilla and the slightly bigger one is blue dream.

I started them all in solo cups (EC ~500) where they never really dried out. I figured they would be better off in the fabric pots so I transplanted them a bit early and they are sitting in the wet medium at about 750 EC now.

Growth has been ominously slow and now the plants are not looking so hot.

If any of you fine folks could offer your thoughts or suggestions for how to proceed, I would be greatly appreciative :)

Do you mean 500 and 750 ppms? On the 500 scale that would be 1 and 1.5 ec respectively. I would go back to feeding 1 EC of the jacks. With peat, the plants like a wet/dry cycle. So I wouldn't be feeding them everyday unless the pots are getting "light" that quickly which I doubt they are. If these were coco, then you could probably be feeding to runoff daily without issues. So just dial back the ppms, feed only once the pots lighten up, and feed to PLENTY of runoff, to wash out any excess salt that is building up. They'll turn around in no time! Good luck!

I meant EC I just don't want to use the decimals lol. I will dial it back along with the frequency! thanks!

I have grown in both Pro-Mix and Sunshine Mix and neither of them required a daily water. Even wee clones still in the solo cups get watered every 2nd or 3rd day.

What is the pH of the source water?

update: I rewatered them with the appropriate EC, the big plant runoff was ~1.5 I think I added more than I remembered. I got the runoff down to 1.1. I got the others to 500. They seem to be improving and growing (don't mind the burnt basil, it needs some love). I will allow them to dry far longer than previously.

Yes, I am seeing now that peat needs little attention which is sad for someone like me who likes to be very involved lol

The PH going in is around 6.8
