Gelato #33 auto first grow!

Sprouted after being in the growing medium for a few days. As this is my first grow I didn’t want to cause any future stress or problems for the plant so I went ahead and planted straight into a 7.5l pot although after some reading this may not be the best for the plant. I also lightly dosed with cal mag as I believe coco doesn’t have any nutrients already there and a percentage of cal mag will be lost in the coco so hopefully I’m not over feeding it. Day 2: all seems to be going well half of the shell has shed and the stem has straightened itself upwards rather than being bent over. The stem is slightly purple so I’m thinking there maybe a great drop in temperature at night time. Quick check of temps etc at the end of the day and the rest of the shell has been shed and it’s started to open up. Day 3: I’m happy with the progress so far the only concern I have is one of the true leaves (I think this is correct terminology) is growing on top of the cotyledon leaf. As expected over the day the plant has started to stretch out and is no longer on top of the cotyledon. Day 4: Not much has changed just an increase in size. Day 5: A slight increase in leaf size and height. I can also see the next set of leaves popping out. Overall I think the plant is progressing well. Day 6: I can’t see any noticeable changes in the plant just growth. Although the leaves seem to be pointing upwards slightly so I did some reading and it’s a 50/50 with some people saying it can be rectified by lower temps/watering/moving light further away and others saying it means the plant is healthy and is growing fine so as the plant is still looking healthy and growing I’ll let it continue and see how it progresses. Day 7: growth seems to have slowed down and this may be to do with my temps and rh. During the day I can keep the temps and rh between 20-27 and 50-70%. At night time it ranges from 16.1-27 and 50-99%. With out a dehumidifier I’m unsure how to control the rh getting that high. Today I have given a light dose of calmag and grow.
