14.4 i switched 12/12 light cycle and 15.4 i gave first bloom nutrients. For now everything seems to go well. Haven't seen any new holes/bite marks or anything like that so i think i passed that problem.
It's gonna be ready around 16.6
The Browning looks like a nutrient deficiency, PH is too high for coco should be between 5.5 and 6.2 with 5.8 regarded as the sweet spot. The ec is also little high 1.8 to 2.2 from feed charts.looking back through the veg stage in sure by having such a high ec and PH, the plant has nutrient burn and locked out.
