What are these little spots? I only have them localized on this one leaf (and one plant out of three), and haven't seen anymore. I'm more curious than anything. Tips to fix? Don't worry?
Do you have any idea what the light measurement is “ppfd” at the level you have your lights? Looks like your leaves are curling up a bit so I’m. Wondering if this is heat and light related
Hey, buddy! 👋
This is the beginning of phosphorus deficiency.
Solution:
1. Adjust the pH of your hydroponics (without substrate) to 6.2-6.3 pH
2. Make an adjustment to the bloom additive - 0.66ml/l
Good luck, buddy! ✊
