I would prune those leaves brother. They have alot of spots on them and if I am not mistaken... there is a little bastard right there in the left of the third pic from the bottom. Wishing you the best of luck with this grow.
I gotta say Mr. those plants still have a long way to go, and with the type of grow you are trying to accomplish i would start fresh with some good genetics, and mite free plants. A few questions, are you planning on letting go of excess meds to a club. because if you are (at least in norcal) they will only take the very best blue dream, and at a low price at that. You realize you have a bad mite problem and if you have the mites i did (the Cali Super Mites) the only the Forbid will work and you need to spray everything in the room.
Also i am very very familiar with both Blue Dream cuts currently going through the clubs, and to achieve over a pound a plant i would suggest something else. those BD's will need at least 4x4x6 to get over a pound so plan for that space. also those BD's dont take well to having problems early on. They are very mold resistant, but mites love them. Be real with yourself, you are going to be attempting a "professional" grow, wouldn't it be worth it to get the proper genetics that are mite free and be able to wash the room down fully in the mean-time?
Im not saying that this mite issue cant be solved, but from your other ?'s it seems like you are new to this, and isnt it better to be safe then sorry?
Blah.. Blah... Blah... insult... Blah... Blah.. Blah...
Awfully opinionated for being the new guy.
