Remove two big fan leaves blocking bud sites below it, added some LST clips to encourage branches to grow outwards a but more. Still can't get rid of the stupid downward curling leaf tips, had it since about week 2 veg I only water when soil is completely dry as you can see from time lapse videos. I have the lights exactly where they’re supposed to be and actually have them turned down a bit more than where they’re supposed to be according to my PAR meter. I guess I’ll just ride it out this way till the end and see how she goes, might increase light intensity another notch later on in the flowering stage, we’ll see. I'm averaging about 625-675 ppfd from top of the plant. I use filtered tap water through a Berkey gravity filter that removes all fluorides and other unwanted chemicals and with the Advanced Nutrients mix it balances out the PH to around 6.0-6.1 every single time, these next few waterings I'll only use plain filtered water PH to 6.0 and see if maybe its a Nitrogen toxicity which is what I suspect is causing the curling and deep dark green color.
