Looks like you are growing in coco coir, so you don’t need a reservoir for anything. Matter of fact if you read most any nute bottle it will tell you that if you are growing in Coco, mix it fresh each time, don’t mix up a big batch of water with nutes in it and leave it sit. For the size pot you are showing there you should only mix enough water and nutes to saturate the pot with a little 10% runoff out the bottom. At the stage you are at my suggestion would be take them out of the pot gently wash off all the coco from the roots, and put in fresh coco. My cal/mag is 2cc/ml per QUART of 8cc per GALLON. And to much of ANYTHING will burn your plants. HTH

That is a spider farmer light from the looks of it…or similar board light…and you have it WAY to close to the plants. Keep it a minimum of 2 feet above and better is 3 feet…I own the 4000 model
