The small one is staying small and I have had the information it won't get bigger due to it being in flower stage now. The other one is going good. I got sensi bloom pH perfect parts A and B and have them on that now. I am giving them roughly 1ltr of water mixed with the nutrients per week. I am still getting yellowing on some leafs but it doesn't seem to be bothering the big one and the little one isn't getting any more yellowing (Touchwood).
