Hi
@Litngrn! It seems that your plant is suffering from three different issues. The first one is over-feeding, the 3 fingers leaves are often a sign of too much Nitrogen during the preflowering stage, and the dark green coloration of your leaves confirms that theory. The second issue is a wrong pH range, a rootmass with a 6.8 pH won't be able to handle nutrient uptakes and will start to show signs of disorder (deficiency, toxicity, or lockout..). Last but not least, your plant suffered from a heat-stress and/or light-stress, your light was too close to the canopy and as a result your leaves are curling upward. Give it a break, stop adding nutrients everytime you water, try to stick to the perfect pH range for soil, which is 6.2~6.5, nothing above, nothing below, and raise up your light to ensure a good temperature at the canopy, you can also add a small fan to improve the airflow, static air is much more dangerous than moving air (for heat reasons, but also to fight mold/mildew and bugs/pests). You might need to re-calibrate your pH pen, just to be safe for the last weeks. Hope this will help, let me know in the comments section if you need any further information, and happy growing! 👊
