Amnesia - Gea Seeds - Coco

So after noticing what I believed to be a calcium deficiency on one of the plants, I purchased some cal mag and have been slowly adding that to the nutrient solution, starting at 0.25ml per litre and going up to 0.5ml per litre, I’ll keep slowly increasing it until I get to 1ml per litre and then keep at this amount unless it looks like it needs more. I also slowly started increasing the amount of canna A + B so at the end of this week, it was getting about 3ml per litre. I’ll now start increasing that to about 4ml/litre which is the recommended amount. Growth has been fairly slow again, the leaves are getting very wide and look very healthy, there’s not any stretching going on and all the node sites are close to each other which is great. Still struggling with keeping it warm enough which I think is playing a big role in the slow growth
