Curl down leaves

Looks overdosed..use just water ...first two weeks .

Stop watering for two days. 600 ppm for week 2 is too strong. 250 should be the target until next week. And cannabis like drier soil. 50/50 soil and coco is too wet. Then water with only water. Water little, like 2 table spoons for one more week. By then, root should grow and you can water all you want.

I saw the photos in your diary, have you transplanted after 7 days, right? Leafs are already curling down on day 8, I guess the plant didn’t like that!

Looks healthy. Reasons for leaves curling down - over watering, under watering, light too close. If these things are OK then perhaps its just still a little early to give nutrients 👍🌱

Hey there , You shouldn’t worry about the first set (cotiledons ) there always turning yellow and fell off . For the rest of the plant tho , seems like it’s overwatered . Yes you Do need to water your plant in coco more often but you should make sure there are enough holes on the pot so roots can access oxygen too ✌️
