First Grow - Gorilla Zkittlez & Mutant

TBH I have no idea what day anything is. I'm going to go with today as being day 13. I made new journals for my other plants so I will keep this one around for my first two plants, Gorilla Zkittlez and the mutant: GG4xHarlequin. Day 13: both plants look pretty short/small for being 13 days old. I'm just happy that the mutant seems to be straightening out a little bit. I let it dry out an extra day before watering him just in case it was getting overwatered. Going to skip using nutes until their next watering just in case mutant had anything to do with the soil being too nutrient dense. Day 18: I can't believe how fast he mutant is growing. He went from being the runt to being the biggest in a week. It makes all the other plants look puny. Now I'm concerned that they are not developing fast enough. I used nutes for the first time on the mutant. He's the oldest/biggest and he needed to be watered. They will be about 2 weeks then. I think I'll water the others with nutes on their next watering coming up. I'm growing in coco so I'm nervous that I might wait too long to start feeding them. All the other plants are growing slowly with only 1-2 real leaves. Maybe this week will be their growth spurt too. Skywalker OG ain't looking good, not good at all. I poked around a few days ago and saw a little tail coming out so I hoped he would have germinated by now. It has been about 10 days for him. I'm keeping him around just because, it's not like I'm renting out his space or something. I had my light on veg this entire time. I started to use both veg/bloom lights at the same time for the past day. It has been heating my tent up way more than I expected. It went from a max of 83 to 86 with "bloom" on. Luckily my humidifier is on auto meaning it turns on when RF < 40 and off when RF > 60 so it's doing a great job of cooling when I turn up the power to my fan, just a waste of electricity. Excited to move everything into the basement in a few weeks. Day 19: all of my plants are staying kind of small. It doesn't seem like they grew after the first week. The only plant not grown in coco was the Mutant which was grown in part coco/perlite/pot soil and he is the biggest by far. It may also be because he is a regular seed vs auto or maybe the fact that he had some soil vs straight coco/perlite. I'm thinking if maybe I really need to start fertilizing sooner. Maybe the mutant is bigger because he already had nutrients in his soil. Anyways, today I fertigated Gorilla Zkittlez first the first time using the same fertilizer I used yesterday on the Mutant. Hoping that Gorilla Zkittlez will grow quicker now that he's got some food. I am able to get the temperature down to 80 by running my humidifier on low and turning my fan up to about 4/10. The humidifier drastically decreases the temperature. Increasing just the fan speed doesn't help with the temperature but I have found that turning down the fan speed helps keep the water vapor in the air longer inside the tent, thus, being more energy efficient. The more water vapor in the air seems to further decrease temperature. It's kind of odd but with the humidity set to low, fan speed 2 = 80F but with the same humidity and fan speed 5 = about 82. Will gather more data.
