I cant quite put my finger on it bro, but something is off. I dont like how the leaves are gnarling a bit and the margins are either dicolored or a bit crisp. Are your stems, petioles purple and or woodsy ? Have you flushed the medium. If you haven't,you should. Try switching from cal mag to epsom salts at 5ml per gl.

Hello everyone. New guy here. Are people washing their coir with calcium to get all of the sodium out? I don't know if people are aware but a lot of coco coir has "trapped" sodium within the fiber. It is imperative to get this out. I have used coir in the horticulture industry and this has been the biggest issue with using it in production on a large scale basis. IMO what I see here is toxicity on the newly developing leaves. Not a deficiency. If you are using a well balanced feed up front you should not see these issues.

Thanks for your responses
