I can see problems on these plants but I’m having a hard time figuring out the exact solution.
There is yellow spots on them. I also noticed some had nutrient burn and I assume the black spots are pests ?
(The white specs on the leaves are from the tent)
Take a look at the “support ticket”. It contains a nice list of various parameters in your plant’s environment, that if known, can help identify what is going on and thereby point us towards potential remedies.
When I made picture bigger them little white things looked like thrips the skinny ones the round ones looked like spider mites. Or i might be seeing things because I had both, and I’m a little Paranoid about bugs.
