My Second grow: RQS Quick One Auto

Last weel was very hot, It cooled down a little (about 30 degrees) in the weekend with some sporadic rain. I've not put the plant into the greenhouse this week aswell due to the heat. I'll put it back in when temperatures go around 25. Which should be next week. The plant is still under the carport due to a constant chance of light drizzle. It seldom does drizzle and when it does it's only for a couple of minutes, but I'm not taking any chances. I don't know what to think about this one to be honest. It's growing crooked (I'm supporting it with a screwdriver in the soil but removed it for these photos) but that's not the worst part. One side of the plant is growing fine while the other one is starting to die down. I've given it no nutrients in the start of the week because I was getting nutrient burn on all my plants, but after a few days some leaves started to die down. Later in the week I've given him a tiny bit of nutrients in the hopes that it will revocer, but it is growing worse. Haven't seen any bugs on the plant, so that shouldn't be it. Maybe a disease which I don't know of. I'm posting another grow question for advice. As long as it stays like this I woun't be too happy, but not worried either. We'll see what next week brings.
