Help with plant issues ,water only soil

[Newbuds]

Hello ,this is my first grow ever , indoors.
8 1000watt lights,. Temp and humidity is good. Ph is 6.0/.6.5ish
Plants are in 15gallon pots.
I use coast of Maine soil (Water only) till now. I reread there soil instructions and noticed it says "feed regularly" organic plant food. The tech said that's wrong after all and the site will be fixed.
So veg was great , plants look healthy and strong. I flipped the light schedule..and they were fine for a week,
About week 2 I noticed yellowing of some leaves,and the top of the plants were light green.
Some leaves resemble nite burn, while some looked like nitrogen deficiency. From what I can tell. (First timer here).
So after reading that they need to be "fed regularly". I got some organic plant food. And fed them ,along with calmag.
No change at all so far.
I did have a issue with mites and acted quickly. I used green cleaner.
Maybe this is the problem? I will post pictures maybe someone can chime in .?
I've Been learning all I can from this forum it is great!

To me, the plants look like they could use some nutrients, I use 20-20-20 general fertilizer. They also look like they might need a dose of calcium/magnesium. I grow under 1000w HID lights as well and they look pretty hungry. A foliar application of a diluted water soluble fertilizer will quickly restore them to better health. A regular feeding schedule might benefit you. I feed about every 15 days, but some feed daily.

Thanks for your help. What soil are you using?

Also I might add. The food I got was 5-5-5. I'm just now learning what it means. Maybe it's too weak?

Update, after some plant food, the turned around, thanks for the help!! Now I know what to look for with this "water only" dirt

5-5-5 it ratio. Just like 20-20-20.
It means how many part per 100 in there if you use 5-5-5 is the same as 20-20-20 you just need to use more of it.

Thanks for the help on that. Makes perfect sense. I switched to 15-20-15 for now and brought them back to like within 4/5 days
