I got well over 50 and I can’t tell ya either. Scope for bugs if you don’t see any spray with some lost coast plant therapy or something similar anyways. It’s nice to hit veg plants a couple times when they are small so you don’t have to worry about it when they get bigger.
That’s just something I would do anyways around that time.
I don’t really don’t worry about small leaf deformations especially if isolated to one leaf. Plants get bumped, pinched, water burn, salt burn, ph issues, fan hits em too much. Could be about anything.
Best to just get in the mind set of keeping things in check before they become problems, spray a couple times 3 days a part with a oil type bug spray like lost coast early in veg and right before flower. Make sure your wet/dry cycles are good. Make sure you PH your water and get some run off. Don’t feed too much. Regularly scope for bugs.
If you do all that and then you see a leaf deformation you can just take a quick glance at it for bugs, and then not worry about it.
