Cherries Jubilee

Kind of a stressful week. I'm really running out of height. I have my light on adjustable ratchet hangers and they are now completely bottomed out, I had to add zipties to raise up the light in order to get a little extra height. I'm starting to see the first sign of trichomes on the sugar leaves. I noticed the leaves and tops of the main colas closest to the light getting a little yellow which I'm thinking was a sign of heat stress, the yellowing at the top has me a bit paranoid and I'm keeping my fingers crossed that it didnt herm and these aren't nanners/bannanas.
