I bought auto flower seeds this year to see what All the buzz was about. I mixed up perlite coco cor a little worm castings and coffee grinds to make my soil, added this to a 5gal geo pot. Now its 30days in and the leaves have turned yellow, drying, and curling up like a Cano while still pointing skyward not drooping. Two weeks ago I gave t a half dose of the first week Hessi nutrients, and this happened... I flushed for fear the nutes are the culprit... but this is now two weeks later and the only change is its now flowering and only 4" tall... please help
