Smoothie seems to have quit growing in height and are budding out. Pineapple Express seems to keep growing and bushing out, slow to flower. Sweet gelato is bushing out and began budding this week.
Looking good bro, iv got pretty much the same plants on the go at 5 weeks, needed calmag in week 3/4 on the pineapple. My first grow as well. Good luck
It seems that those of the central line, grow more slowly.
Have you tried changing the pots? So, you can check if the lighting works uniformly.
Sweet smokes!
