Green Cush grow aka Green Crack

Sry not greatest pics. Exactically 25 days into flower. 34 days from 12/12. I woke up and check my babies as I do every morning lol and 2 largest were getting yellow from bottom up 😳classic nitrogen deficient as I am holding back on it a bit. Contrary to what some other growers think you do need nitrogen in flower period almost as much as n veg but to each thier own. They are green again and we’re just hungry 😋✌️😎
