Asking for a friend eh? But you are using fox farm ocean forest soil eh? Anyway, it does look like a bit like a calcium deficiency. Some cal/mag will help, but the affected leaves won't bounce back to normal health. Once damaged, they stay damaged, but all the new growth will be fine. Hope this helps, Organoman.

Leaves turning yellow with brown patches I noticed the first real leaves on one of my plants turning yellow in FFOF. I transplanted them into bigger pots with ProMix M in hope that it would stop. Condition seems to continue worsening. I have started to notice the cotyledons on some of the plants turning yellow.

Orange/Yellow spots on leaves Today I noticed that one of my plants has an orange/yellow sign on a couple of leaves (see photo with the tag "28/02"). The spots are small and the leaves seem to be healthy (so far). What the problem could be?

Nutrition deficiency or nute solution on leaves during watering?Hi Growmies,during my monitoring routine I found some brown spots on the leaves. Not many but on some leaves the brown spots have become transparent and I can see through the leaves. Any ideas what could have caused the brown spots? Perhaps not enough CalMag? Rest looks healthy.
