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

Base gets only ab, calmag, silica and (will) pk 13/14 Pro gets the complete line Pro is growing very well, i've started a lollipop process, will slowly prune what is not necessary, i don't know if i'll do a full lollipop or what but that's it, i'm also trying to keep everything leveled with the trellis net and garden wire, i have to say it's more work than anticipated, various branches always try to be dominant over the other. While pro is still growing strong, base kinda stopped, i've pruned some little branches and leaves to base as well. I've started lowering a bit the pH of the feeding solution, the relative run off is having me a bit worried being always at 6.3-6.6 range with feeding solution ad 5.7-5.9, the EC of the run off is lower than the feeding solution tho so i don't know what is creating this situation. Pro has started drinking a LOT not even 5 liters is enough anymore, i've started giving her twice a day 7.5 liters (that's a bit too much but i have 30liters jug so i prepare it all at once and have it ready for 2 days, lowering the amount would just leave me with strange amount of solution that I would not know how to give)
