Organic Cream Caramel CBD

I think my first topping attempt has been successful. Also it looks like she handled me trimming her lower growth. I did this because I don't see the point of letting that growth continue and take nutes from prime growth if I plan on lollypoping her anyway. I waited for the tops to start growing and only removed growth from 1 node at a time with a 2 day break between defoliation. I usually use RO water for the garden but it looks like she is starting to yellow slightly. My grandma always told me that Epsom salts will make plants more green because of its magnesium, with no Epsom salts available I just let some tap water dechlorinate with an airstone for 24 hours. This should supply some magnesium and calcium until I transplant into 1 or 3 gal fabric pots with more Gaia Green mixed in. Any opinions on what size pot to go up to next? I can't grow monsters though with my limited space.
