I usually don’t but some growers mentioned certain strains can take it with some growers feeding up to 3000. This was a pretty aggressive strain. Constant pruning and training and she loved it. If not it would have been a bush. i guess their method is to test its limits and slowly see how far it can go without getting a nute burn? But so far It’s been doing fine in terms of not getting tip burns. But that was my last feeding of 2200. I don’t intend to go more than that. I started her off in the 200ppm and worked our way up slowly.
