Strong LEDs does not lead to cal mag extra consumption by the plants , what is leading to this phenomenon is the light 20/4 to 24/0 light schedule that makes the plants using more Cal mag. Of course if you want to grab a cal mag bottle and add some extra cal mag to your mix just to prevent an eventual deficiency is a good idea as long as you don't give too much. Now when I takes a look at your plants I can't see any signs of cal mag def so don't worry.
If one of tour plant have been under watered it is not a big issue even if she dropped a leaf of 2 because a watering will fix that as soon as the plant has no dried area. Calm down , add some extra cal mag just in case

Plant looks great I dont see any major issues. You may be dripped nutrients on the leaves while the light was on which intesified the water droplet causing a burn spot. Try to only water the soil or try to dry the leaves with a small fan to dry them before the light comes on. Hope this helps put your mind to rest.

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?

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).
