Have seen similar damage on indoor plants getting hit with winter drafts. The cold, dry air, can sort of, freeze dry leaves, and strip the cuticle layer. This started before our little cold snap last week, tho.
My first thought was some sort of rust fungus eating the leaves. The incoming air isn’t filtered so it’s a definite possibility, but no other plants are affected.
I have three, and the other two are literally half as big. Same soil mix, same volume, same living conditions, and they all went into flower at just about the exact same size.
<An oz of bud plus a cup of oil, in a mason jar not even finger-tight, in a pressure cooker. When the water comes to a boil I close the cooker and let it run for thirty minutes, before passively cooling.
Ovens suck for decarbing. Pressure cooker is within ten degrees of ~240F, every time, and the smell stays in the jar. I think it might still be a little under-decarbed, but I don’t have the ability to test what the optimal timespans are, yet.
Good idea for decarbing with some control over those high temps. I would not even think a pressure cooker needed just check the temps of the hot oil in the jar. Maybe use that MCT if could handle the temps.
Okay I clearly mixed up tags on seedlings, and this Mekong is definitely not a Mekong. If you believe this is a purebred sativa I’ve got a bridge for sale in Brooklyn.
