Iâve got to say youâve got me a little stumped. Your plants have shown nute burn from a very early stage of growth on through now. But I dont think thatâs the only thing that is causing your drooping leaves I believe that is because your low humidity. Your plants look to me like they are getting to much mag but the only nutrients that youâve listed donât contain any so there are some inconsistencies that arenât making sense to me.
