Can anyone help sort out the issue I'm seeing on the lower leaves? I think I'm either between nutrient burn or potassium deficiency? I did up the nutrients a bit this week when I saw yellowing, but also have had high runoff pH the whole grow. Though haven't seen any other issues.

The plants are now placed in rows, not on the windowtill but behind & below. This means that theyβre: 1. Growing towards the window once again 2. Have parts of them barely exposed to the sunlight. What do I do? Do I let them grow how they want to? Should I trim away some leaves?

seed husk fails to fall
most of my seedlings sprout and the shell husk never really 'falls' off. when I wait for nature, I end up with 1 or more rotten cotyledon. -planting shallow in peat plug. -never get roots to grow to bottom. -do I need to plant deeper into plug so plant can get better grip?

I'm using a coco mix with advanced nutrients organic. I water 1l everyday with little to know runoff.The new growth is a lighter green and the leaves are thin. Is this some sort of deffinency or toxicity? I recently just flushed and stared giving half nutes.

Brown spots on leaf tips of old growth.
Hi all! Brown spots are starting to form on the old leaf tips of this young lady. I've had contradictory suggestions as to wether this is nute burn or a deficiency. Nutes were started on d12. EC has been stable at .51 (PPM 360) for the last 5 days along with PH at 5.8. Cheers.
