Best thing is to watch your plants. I just started using teas in combination with Pura Vida organic nute line and for the first time got leaf tip burn. I cut the nutes to half.
I asked an amazing grower how he got his results and copied him to the T. I don't care whether bottled organics are real organics or not, it's the end product I'm interested in, not some ideal.
Way to go Seamaiden.
