As far as I know, Calmag is recommended for plants that we grow in a box under LED lighting :)

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

What happens if fan leaves all fall off before maturity?This is first time ive dabbled with ilgm autos. Plants grew twice the recommended size and are on the 9th week. The pistols are 90% white and the fan leaves are yellowing fast. I've never experienced this and am afraid the yellowing will affect buds before ripe. Suggestions?

Yellow Leaves AutoflowerNovice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)
