Is this normal new leaf color growth?
It seems again that my leaves are a touch shiny, slightly curled down, and are a touch yellow. I water only 1 Liter every two days and do not use any fertilizer apart from coffee grounds and aquarium water which has slight minerals. Thanks for the help in advance

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

Drooping leaves
The water pH wasn't right before but it's been at 6 for the past 5 days and the leaves are still drooping and seemingly yellowing albeit at a snail's pace. Water her every 2-3 days + 0.5 ml of feed once a week so not sure what the problem is currently? It's an organic grow.

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?
