I really don't like these plants. Seems like no matter what environment they're in, it's fan leaves are burnt. New growth looks great. Just the fan leaves are crumby. Seems like whatever amount of light I give them is too much. So now they're stretching like crazy cuz I backed all the light off. Really don't care if they die at this point. I germinated another one and it seems to be doing great. growing 4 other strains in the same room with the same everything (organic nutes up until now) and these just don't perform. All four plants don't have pistils. Probably males. No signs of sex at all. So I got irritated and broke out old dynagro foliage and fed them that at full strength. I also broke all the interior of the stem walls to help with uptake. I also pulled all the fan leaves which is ridiculous in veg. No point. They're just pissing me off.
