Grow #2 (Jack Herer & Blue Zkittlez)

Jack Herer start of week 5 Flower Blue Zkittles start of week 3 Flower After a week of big bud coco without calmag the leaves were showing signs they needed more, bright lime green leaf with dark veins so I added it back to the mix. Removed the Net aswell because ill be adding another plant to the tent in a few weeks, I like to rotate the plants aswell obviously I cant do that with the net. I'll either leave them without supports or maybe get some tomato cages though its probably too late for that. Let me know what you think..will they be fine without support? what do you use?
