My dad had been growing for awhile now but he is running into this on a few of his plants. He hasn’t changed anything from previous successful grows. Water, soil, nutrients is all the same and fresh.
These were started indoors until about two foot tall and planned outdoor. Zone 5B. Watered daily, no water logging off soil. All three were started from seed and all the are different strain. My dad is very experienced with this but I am not. If I left anything important out please let me know and I’ll get the info from him.
If he replants outdoors yearly, does he use the same spots ? If so the soil may have become acidic or basic. You check soil pH if it’s a repeat grow area. If it’s planted in like a field ,there may be other plants competing with or cooperating with the plants
He plants outdoors in 2 gallon pots. Every grow he replaced the soil. The brand he uses is happy frog. Only three of his plants have this the other four are ok.

That’s a good point. I don’t think he has been here. After you mention that, two of these plant are in cloth pots.
