I am sticking with straight jacks 321 recipe after talking with them. They said its got low enough N that it shouldnt burn with all else good. I get it environmental factors are showing hardcore, I am coming from verticle hanging hps bare bulbs to a tiny ass tent with a gigantic tanning bed inside!
Clearly Got to dial light back to slow metabolism. Back to 50 and watch the blue dream. They barely into bud at day 8. Looked like they were a bit greener but the GDP maybe getting rust spots, she's taking off though. Strong plant.
I have dimmable HPS bulbs and I do this with HPS as well.
Week one is 60% strength and every week I go up 10% until I'm maxed out.
I'm usually at 2.2 EC start of flower and end up at 2.5 by the end. All depends on cultivars honestly.
