Test-grow tatanka pure CBD | is it worth to use the full nutrients line or just the base nutrients are enough?

Base plant gets only silica, calmag, and A+B. Pro plant gets all the rest mentioned ; removed first node growth tips on day 29. Starting again from what I wrote in the previous week, I'm playing around with the nutrient solution concentration, 1ml calmag, 1ml silica, 0.8ml A, 0.8ml B, 2ml rhizotonic, 2.5 ml cannazym, in 1 liter, the correctly calibrated EC tester, gives back 1.3EC, and base plant solution is 1.2EC (included are some drops of ph- for correct ph of the solution), but just the silica and calmag gives back 0.6EC, so that does not leave me much more to add the A+B. 1.3 is indeed too much atm so I diluted it to 1EC with RO water and thus, since I do batches of 5L of solution I will have to use this for the next 3 feeds (I feed twice a day), but from the next batch I will probably give 0.5ml silica and 0.5-0.7ml cal mag, to have more room for A+B (cannazym and rhizotonic are not the problem, I tested it, these quantities add only 0.1 EC to the solution). Base is not very vigorous, after topping she's now still 12cm tall on day 30, while pro is 20cm, even tho, she's not sick, I don't know if I just got one seed which is vigorous and tall genetically and another one which is much bushier, or if the difference in feeding is that influential on growth, but probably a much larger sample would've been better to test this, but well , that's what I can afford to do now. Plants are responding very well to the toppings + LST especially of course pro, after a few days of 1EC nutrient solution, I calculated EC of run off and it had plenty of room to give the plants more nutrients (0.5 EC pro, and 0.6 EC base) so at the moment they are getting 1.3 EC pro and 1.1EC base
