take it from someone who's used maxi for over 3 years, it's not the simple way to go. between the constant ph adjustments to your res, calibrating your ph pen monthly and the flushing everyweek because of salt build up, not to mention how easily it is to burn your plants. i've ruined what should have been some pretty nice harvest by over feeding. And the quality of the nugs, even after a week of flush i can still smell and taste that's seems synthetic IMO.
you should NOT have to add extra calcium if you ph is right, maxi bloom/grow is a complete nutrient. If you see deficiency when?? if you add grow during the flwr period your going to feed them too much nitrogen. In my experience with maxi if you see a bit of def in flwr you probably need to flush ASAP, don't fck with the 80/20 mix (IMO) you'll be wasting valuable time.
If your add calmag during a calmag def, instead of fixing the root of the problem (the PH), your harvest will be in a world of hurt.
2 part Advance sensi bloom ph perfect/sensi grow ph perfect is what i use. i'll never be going back to maxi line.
THis is just works for me, my PH pen is just still there collecting dust and my tree's are super lush and green. I've been able to focus on other problems in my room like temps and spectrum. i hope that doesn't come off like im telling you how to grow.
