Looks like Deficiencies, can you help?

Please tell me more about over watering and how it can mimic many different plant deficiencies. Currently I am using a bubbleponic drip system, I have 5 drip tubes hooked up to a 185GPH submersible pump which is only on when the lights are on. Im using 17/7 for my lighting schedule. I've heard that maybe I should only have the drip system on maybe three times a day 15 minutes each because I could be over watering having it on for 17 hours straight, what do you think of this?
I am starting with clones, and wondering if I should have used less nutrients. I used 1/2 of week one nutes, so I used 1tsp/gal. I also used some earth juice catalyst 1/2 tsp/gal, super thrive 1 drop a gal, fulvic acid 1/2 tsp/gal, and hygrozyme 4ml/gal. All this to start clones that show roots through rockwool.
My clones have very slight yellowing around both edges of newer top leafs from the back to the tip with normal green in the center, some new young leafs are slightly twisted and very pale (IRON?). Some leaf tips are pointing straight down with the rest of the leaf bowed doward yet horizontal. Other leaf tips are slightly pointed upward, and some are very very slightly burned or browned. The stems are purple, yet the very top of the stem where new shoots are slowly growing is still green.

The nutes i am using is rated at 3-1-5, is this too weak? wrong ratio? what is better?

My PH is ok 5.8-6.2(constant), I have I monitor that constantly with a ph meter freshly calibrated.

Lately I've been having issues with vigorous growth, some nutrient always seems to be deficient, I want to know if I should add earth juice micro to the reservoir at water change at low dosage and what that dosage would start at for clones

Continuous drip into rockwool will not let the roots get any oxygen (unless it's a big plant in a small cube). Also sounds like a lot of nutes. Just use the grow formula till they can handle the all other shit too.

thats what i was thinking, so i flushed the rockwool with 6 litres of low ppm water and now using foxfarm nutes, then i bought a hyrdrofarm 15 min timer, you can set it to go on and off 15 minutes at a time multiple times a day. So now i have the rockwool getting watered twice a day for 15 minutes. Once 45 min after lights come on and the other right after the lights go off. what do you think about this? should water more or is that suffiecient

That's just about perfect what you got going on there. Check to see how heavy the rockwool is just before the second watering and adjust as necessary.

Maybe something here symptoms might help? Good luck.

Ok, well it looks like foxfarm dd it again, man these nutes are great, i love the fact that you dont need to add micro nutes. This other organic stuff i was using was not working, plus i neede to add micro, and i really don't want to do that extra measurement.

anyways, here are before and after pictures of my plants, as you can see the pic with the tops of the plants light/lime green is when the deficiency occured, the picture with the new top green growth is two days after i flushed the system and replaced it with good'ol foxfarm nutes

does it look like it is reviving properly to you?

Lookin good my fiend.
