Greenhouse feeding bio
Dechlorinated tap water 90ppm add calmag to 250ppm
Ph between 6 and 6.5

Any suggestions?
Your growing in coco coir your ph levels should be 5.9 in veg then raised to 6.2 in flower it look like a bit of nutrient lock out caused by your higher pH levels just feed plain pH water for the next few feeds then restart nutrients with ph 5.9 solution
Ps yellowing leaves won't improve but you should see no new yellowing
Best of luck with your grow 💚
