Help ! Is this an overwatering issue? I am growing in hp promix coco which is mostly peat and coco Was feeding everyday with water and

I grew in promox hp for a short while and it had pretty heavy peat and stayed wet for a while. I had overwatering issues for a bit and started waiting until I seen the fan leaves starting to umbrella then feed/water. I also ran into manganese issues usually starting about week 4-6 of veg. I had many I was watering once a week for a while but got more frequent as the grow went on. 6.2-6.3 to me is the high side and prefer 5.8-5.9 in Coco but do go up and down with it. Personally I'd let them dry out a little bit, add some mycorrhiza and cal-mag on next water. Also when you do water look for run off, it helps with build up which for me is a common issue in Coco.
