Blue Fire (blue dream x fire OG)

I think I will stay on the same nutrients measurements for this week. The plants don't look like they need the increase just yet. I've also been looking at the grow plan i pictured in week 1. It shows the flowering will start i 2 weeks but I will probably extend it another 2 weeks. Than or untilI believe the right size has developed. I have fresh air coming from outside but we are unexpectedly cold at the moment. The outside temp is 3 degrees Celsius with a real feel of -1. So I am struggling to keep the temperature up. So I have been looking back over the last 5ish weeks, thinking about what i could of done differently. Quiet a bit😆! The repotting was unnecessary, i should of probably just put them straight in to the main pots. I believe the feeding amounts are too heavy for the plant, so I'll keep to the lower end of dosage. Few over waterings so the medium in turn was colder then what is ideal. I also didnt feed them plain water very often. Struggling with temperatures and humidity. I have a controlled humidifier due in 4 days and warmer weather. This grow and the two auto's are my first time with canna and coco. Mainly i think the two repottings slowed them right down for a couple of weeks along side everything else.
