Having issues a few Weeks into Ebb Flow and RO water see leaves in pic

[MrPharmer]

This is my very first time doing a hydroponic grow my first grow was with Ocean Forest Foxfarm soil and I did fairly well with it I decided to switch it up I purchased a green trees system and I’m using smart pots with a 7030 mix Coco Perlitei am flooding 15 minutes a day plants looked healthy for first few weeks now they are lighter green and stripped a bit looked like mg deficiency so i top flushed then did epsom salt flood dumped reservoir redid Nutes lower strength
Temps range 71-82 air flips on at 82 via sensor
Humidity mid 50’s - low 60s depending on if fans cycling fans are turning on momentarily in this pic doesn’t go higher than 65
See images any pointers
I use GH Nutes flora trio and calmagic see image of feeding schedule used

Are you top feeding them at least once a week? Problem with ebb and flo is you will get salt buildup at the water level and it will continue to buildup. Always a good idea to flush nutes through them at least once a week to counteract that problem.

Also you can dump the calimagic and just up the micro for Ca in the future. Also with that schedule it should me calmg first then micro-grow-bloom. Also something like hydroguard/H202will help since temps specially if you have a pump running in the rez (which you shouldnt)
