This is definitely a magnesium deficiency but it's not from lack of magnesium but a actual nutrient lockout. After reading your diary I think your ph could be the issue 5.5 is a little low even for Dec. I would try raising it to 6.0-6.5 this is perfect for veg when growing dwc.

Looking pretty good so far dude... I've had many plants be fine with a PH of 5.5-6.. and also had plants that found it too acidic.. I agree with Mr. Weeds Autos... Sometimes shifting to a higher ph.. Ie 6.2 can really improve the overall vigor of certain strains. But ideally you want to fluctuate a bit. Cannabis plants absorb different nutrients better at different PHs.... Bouncing the ph between 5.5-6.5.

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?

What are these symptoms?Hello everyone!
My plant is currently experiencing a few symptoms that I don't quite understand. Pics 1 and 2 show them the best, with the leaves from pic 3 to 5 having similar, not so heavy symptoms.
Pic 6 I believe is something else, Not windburn though, leaf is too far inside
