Hello Friends! New to indoors any advice helps.

I am growing in a 2'x4'x84" grow tent. I am using to 4" inline fans, one in my tent to vent out stale air and one outside my tent bringing in fresh air from outdoors. I am currently running 2 mars hydro lights 300-60LED, I use Fox Farms Ocean Forrest soil. I also use rain water with a little PH up to get it around 6.8-7 and use .6 ML of mammoth P. As a nutrients I use granulas Meigs Formula 1 and 2 for flower. Was just asking around when to flower my photo period plants. I am trying out LST my first time. What you guys think?

Don’t ph rain water...works as is. Matter of fact there’s no need to ph the water at all. Ever. The soil mix itself sets ph not the water you give; unless growing in a soiless medium like coco ph adjusting the water does not affect the actual ph in the root zone.
A good rule of thumb for flipping to flower is to wait until the plant is 2/3 as large as you want it to be in bloom. With blurple led panels you don’t want too deep a canopy. Panel style leds only penetrate a few inches of cola so err on the short side. I would give this plant maybe another week or two of veg but no more.

Cool man that's awesome. I was thinking another week as well. I have removed so much growth the past 2 weeks its unreal. Thanks for the feedback man!
