Odd discoloring and unhealthy plant

[splinter7]

i’ll try adding the epsom salts instead of the calmag and see if that fixes it. its just a perlite hempy, so just grow nutes and peroxide, sometimes calmag. i will start up Si once i get through the LST on all the plants. once in bloom i use just basic bloom nutes again and do the koolbloom wet from week 3 and dry from about week 6 to ratchet down the N.
