Nute issues with first time coco grow

OK so I had an issue with my first autos. Was initially treating them like they were a soil grow for the first week and I feel I crippled them. Now I see almost no growth day by day. I still see growth but it seems extremely slow. I have educated myself on how to better grow in coco and since then the plant has recovered greatly. It was initially not growing much at all for the first week and was very lime green.

Now I am on day 20 and growth is still very slow but most of the color has returned to a somewhat darker green. The question I am having is regarding my nute solution that I am giving my plants. I am seeing towards the inner parts of the leaves yellowing on new growth. Just want confirmation that I am correctly feeding them and that the slow growth is more likely due to the first weeks mistakes than the current feeding schedule.

I currently feed my plants 3 to 4 times a day and measure run off EC and get around 1.3 EC for run off. I am currently feeding them:
tap water with EC around .4
Jacks Orchid Special 30-10-10 1/4 tsp per gallon
Cal/Mag 5ml per gallon
Brings total water EC up to 1.1
PH between 6.1 and 6.25

Main question here is I see a lot of people posting different nutes and I just want to confirm giving Jacks 30-10-10 is good enough for veg. If not if someone could please explain why instead of just recommending different fertilizers as I am trying to understand why the Jacks is not doing a good enough job as it has 3 times as much nitrogen as the potassium of phosphorus while still having smaller amounts of those to provide the plant all recommended nutes.

Don't have pics on this computer so will be posting another post in reply to this one with pics of current progress.

 

Just dont know why thier moving so damn slow?!?! Should I be giving more nutes?!!?
