Redding, red Bluff, same thing. IMO that greenhouse is what is killing you and has been slowly for quite some time. You’re a little feeding fiasco probably just push things over the edge. I think those plants should’ve been put outside when they were two or 3 feet tall max. Plants can handle this heat if you can get a handle on their care. Big bags at least 25 gallon help to keep the roots relatively cool.I’m going to make myself unpopular here and wager that every plant in that greenhouse is stretched and anorexic looking. They tend to grow a little slower out in the sun but they are stocky and hearty by the time it comes to support some weight. I think your greenhouse is good to get an early start on plants so you can get them outside as early as possible. But after a month or two it becomes detrimental. Sure, some of the big boys run full-term in a greenhouse, but it is climate controlled pact with supplemental lighting, and I’ve driven past them up here in the hills where the sides of the wallsCan be raised and lowered for ventilation and light. And a lot of them just use the greenhouse for breeding, propagating clones and Seedlings on a large scale. Just something to think about for next year. Growing full term photos in a greenhouse like yours is a recipe for disaster, but don’t give up, experiment, tell your old man to wheel them out on a dolly and put them under a shade tree for a couple of days and then out into the sun. What the hell do you have to lose? Good luck, neighbor!
