Does everything look okay? I'm new to hydro/soiless growing. Thanks!

Here is my DWC bucket. It has 3 gall of water in it. With 7.5ml's per gallon of botanicare Calmag, and 1oz per gallon of some hydronute I cant remember, which was cheap, and recommend by the shop worker. Ph'd to 5.7-9 fluctuations. Here are some pics of the roots, and of the plant from 4 different angles and views. I thought it was a calmag problem, specifically cal. But I can't get it to stop, although it's not affecting growth at all it seems . Here's the roots:



Here's the plant; diagnosis?:







Here's my ATF coco plant:





Do you guys have any advice on each?

They get the right ph'd water and heavy feeding of calmag, so idk whatsup -_-. Is it supposed to be 1 heavy feeding of calmag with nutes 1 time a week, with just light calmag and water the rest. Flushing it every 2 weeks with that sensi salt grabber thing to remove salt build ups?

Thats a ton of calmag. I use about 1.25ml per gallon in aero and dwc.

Looking pretty good for a virgin. Just keep an eye on that plant with the yellow edges, probably nothing to it as the rest of you plants look great. Nice roots too.

Well the fan leaves on the DWC look like a cal/mag def.so I added more...then it still kept moving. So I went with the inbetween a heavy and average feedingof the cal mag. So even with those weird fan leaves(maybe you cant see them from my pictures?. It looks okay to you guys? The atf plantin coco is shwoing what looks like calc problem. But I think it's because I let the coco dry out a little too much. Not dry, just too dry to where the nute concentrations are high and it burns/locks it out a lil. So I'll keep a better eye on thaose coco plants.
But all in all you guys are saying they look pretty solid, and the roots are good For a first time? Great! Thanks guys. I thought it was a problem. But if you guys say no, then I'll take the veterens advice.
