Hey, buddy! 👋😇
If you're growing in coco or in its soil-less mixes, then water with a solution at 5.8 pH for good flowering! 👆 Your pH is suitable for soil, not for hydroponics! Coco or "soilless" is hydroponics, bro! 👆
When growing in "soilless," you water the plant with nutrients every day! During flowering, the plant loves a Gro:Bloom additive ratio of (1:3) after the middle of flowering; you can do 1:4. 👌
Good luck, buddy! ✊😇
