Well I have been at this for a while now and the only part I hated was moving my veg plants into the UC. As soon as I did that I got zero growth for weeks. Very frustrating to say the least. I use RO water and Canna nutrients with Advanced BB and OD. Just about every start was the same for me. When I first came here they put the fear of god into me about using cal-mag, to much is the kiss of death, don't use it bla bla. So after reading and re-reading this is what I came up with.
Most of the better nutrients are buffered to help maintain Ph in water. The buffering does not work in RO water you need to mix 1/2 and 1/2 as per manufacturer instruction. Canna recommends .2 to .4 ppm in your water to work right. So because there is nothing in the RO water Ph is hard to manage and there is also zero value in your RO water. So this time around I added 2ml per L of cal-mag and both of my stalled systems have taken off big time. In fact this is the first time I have had to worry about roots plugging my system. Very big difference. So now I do use Cal-mag and my plants are not stalling. I use the cal mag with my regular nutrients. Boy it is amazing what a little cal-mag can do.
