Definitely check for pests because it looks like that but if you can’t find any and no sign after using some sticky traps then use a dose of cal/mag with your next feed and assure you Ph is on point for your grow methods.

looks more like bugs/pests biting it.
leaf looks heathy ... inspect underside... maybe use a scope to see the tinier pests.
if you watched it progress and are certain it is something else... lower twisted leaves would help confirm a Ca-def.
i'd look over your dry amendment labels... it likley contains Ca. your soil likely contains lime of 1 or 2 sorts... Ca is in your water, unles using RO etc... Usually ca symptoms are ph or lockout related when i see them on here than an actual Ca deficiency.
I'm still putting money on a bug/spider or a passing bug that took a taste and moved on..

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

Branches growing on leaves?Has anyone seen this before, branches growing out of leaves? I have limited experience growing and this was a first. I had to trim this one because it was shading some bud sites, but I didn’t notice until after I cut it.
Weird or no?
Thanks!

StainsWhite dot's have appeared on one leave of the plant, while the other has this weird stains.
Yesterday evening I've sprayed a bit the plants with water. This morning they had nothing, they appeared in the late afternoon.
Also the base seems to have some some white grains (roots?)
