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.
One blue dream One space candy One cherry pie
All hybrid strains. He also has another space candy that is doing well.
maybe the heat, everyone shaded the same all day?
See my above comment, but I will also say that Cherry Pie is notoriously finicky in my experience. I dumped that strain after two rounds because A: I didn't like the genetic that much and B: it always got locked out while the rest of my plants were going gangbusters. Blue Dream can withstand a nuclear holocaust though. I swear you could piss in the pots and get 2 pounds off a plant.
I'll pass this along. One of the plants seems to be bouncing back better. Wonder if it's the blue dream.
