First Ever Try (Seed Stockers)

When they were young they were trying to tell you that the medium was a bit hot fr them but now that they are acclimated they will soon ask for more nutrients

Can never be certain with only pictures but it looks like they're saying. Hey man why are you drowning us?

IMO, that leaf is nothing to worry about. If indeed you just fed a little, stop and wait a couple of weeks. If your soil is quality/rich, that will hold you for at least 4 weeks, but more like 6 weeks. Depends on your strain's ability to absorb nutes. Since your plant is still in veg, it will grow out lots of leaves, and leave the lower ones behind, to trim, as they will be under shade.

Hello It looks like a reasonably healthy cola to me. I see how some of the sugar leaves are a bit twisted and curved, and the leaves seem to be a bit dark green with some slight tip burn? I think as you drop down the nutrients in this last 2 weeks you'll see a change in the leaves. And the twist, are they having much wind? If so that can be a good cause for that twisted growth. I don't think it's anything too serious like pests or rot. Just keep giving it TLC, lots of sunshine, a healthy wet/dry cycle, and a few days flush at the end and I'm sure it'll be a very enjoyable bud.✌️ happy trimming.
