Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Do I have an (Mg) issue?
Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?
