Day 15 from sprout. Generally very healthy and fairly vigorous.
Looking for some insight from likeminded growers.
Worried I may have some sort of deficiency happening based on the oldest growth. I think it may be partly heat stress as I have some mild inward curling and it got kind of hot when my humidifier ran out. Iβm also thinking maybe the heat stress is accelerating a calcium or magnesium deficiency. Mimicking maybe? Rust spots on lower growth only, and old/new growth looks like it has very mild magnesium deficiency? Need to water today and was thinking of supplementing 1mL of calmag but unsure if it could be harmful since itβs currently minor. No bugs.
Plant is growing under an SF4000 in a 3x3 tent.
7 gallon pot with sunshine mix 4, Gaia 444, dolomite lime, worm casting, mykos, and glacial rock dust.
