That looks to me like it had a momentary calcium transport issue. What you're seeing on the leaves is evidence of a past event and not necessarily a current problem. Just watch out for EC spikes, bad pH values in the water, VPD hard swings and cation getting out of whack as they're all potential triggers, and sometimes a plant just has issues regulating its own calcium during growth spurts when everything is otherwise dialed.

that makes sense---i use liquid to ph then i switched to a vivosum ph pen... thats when i started seeing them..
the pen wont calibrate correctly...so i went back to the way it was with the liquid, so i can balence the ph out...
THANK U SO MUCH ALL OF YOU FOR UR HELP!!!

Those pens are damn liars! I gave up trusting them. A $10 bottle of GH pH drops will easily outlast 5-6 pens that quit calibrating before you start to run low.
