So recently i tried out some new seeds and i feel like with chemical ferts your always guessing when it comes to nute burn. Some strains react better than others to nutes and im tired of seeing yellow leaves on some of my more sensitive beauties. Ive heard their cries and finally im switching over to organics. i decided to start off with pure blend bro. I know its now 100% but its close enough starting out til i learn enough to make my own teas. i got PBP Grow and Soil and liquid karma as well. What im wondering though is will i need a cal mag supplement? Ive been growing for a while and most every plant ive ever grown ends up deficient if i dont supplement. What are the organic cal mags out there? are there any? id prefer to go with a premixed, straight from the bottle nute but i know part of organics is that those dont always exist. Anyone got any suggestions for me?
