Can you tell us what you’re add to the medium and what medium it is?
How far away is the light? Is et cetera et cetera? Anything you think will help
Kinda looks like a magnesium deficiency, but I’d like to get a better look at the whole plant if you could
Thanks for your reply!
I am using a simple store bought potting mix. The medium pH has been fluctuating between 6.5-7 over the last few weeks.
I've been using a organic nutrients fertilizer with the following composition (found on their website):
Nitrogen - 2.07%
Phosphorus - 0.107%
Potassium - 1.95%
Plus: Sulphur, Calcium, Magnesium, Sodium, Iron, Manganese, Zinc, copper, Cobalt, Boron and Molybdenum
I've stopped adding grow nutrient once I saw the yellowing increasing. But it seems like it got worse.
The lights are about a half meter away from the most effected plant. Overall growth seems to have slowed down.
In this set up I have multiple plants all showing varying signs of nutrient problems. Also I had a caterpillar infestation ;(
The first two photos are of the most effected plant. Followed by the others in this set up.
Thanks in advance.
