Nice start to a 1st grow, nice to see somebody do some studying prior to starting.
Speaking of bugs. I was trying to look real close to your recent photos of your new clones, and in photo # 2 it kinda looks like there are little yellow spots on the leaves of the clone at the bottom of the photo, could be wrong , old eyes, small photo etc. but if there are little yellow spots on the top of the leaf then most likely you have mites.
I don't know your life style, but with a tent in the bdrm you're going to have to deal with bugs, it you have pets, that go in and out, you will get bugs, if you go out in the world and touch nature, you will get bugs.
You can deal with them once you know you have them, which means they are already thick in most circumstances. Or you can do maintenance and keep them from ever showing their evil heads.
Treatment is the same either way with any toxin you use (toxin to bug that is). The most friendly method is with "Neem Oil", or "Rosemary Oil" or many other natural oils. Then there are the Azmax series of products, which I personally haven't used.
I would personally recommend Neem or my current favorite "freti-loom - Fruit Tree Spray" this is an miticide, insecticide, and fungicide. No matter the product if you get bugs you have to spray once a wk for at least 3 wks. I do maintenance and spray every week till week 5 of flower and I don't have bugs period.
A lot of talk about your ventilation, but if you are going to add a 2nd fan, make them both exhaust. 1st the light, set it up the way you started with an intake duct from outside the tent, and extent it outside the house, as was mentioned earlier. Then the 2nd fan is for the tent ventilation only, carbon filter in the tent, sucking out and vent it outside also if possible if not vent this one in the bdrm. Inlet to tent, again as mentioned before, use a piece of flex duct from a bottom inlet, put a couple of curves in it, to keep the light out and keep the end off the floor to minimize bug intrusion. Keep the tent closed as much as possible.
Nutes- The FFOF soil will do for the youngin's. For the plant that's already in the 5gal pot (not a good idea,,, again as mentioned) you are going to have to use some liquid ferts, and there are 100's. I would say keep it simple in the 1st grow and go with something like Botanticare or a basic General Hydro product. You'll need a grow (veg) and bloom (flower) product. I have many ideas for the future growing of the clones fert schedule, but you should stick to one program for all plants during your 1st grow. (Use the Botanticare I've never seen or heard of anyone kill with these ferts)
Rule of thumb - More MJ plants have been killed from over care than from neglect.
I wish you the best of luck on your 1st grow, be patient and good things will come.
O when i said training I meant .... topping.. supercropping .. lst ect.. just ways to get more yield .. manage height and increase the amount of big cola's .. Specially with a 400 watter.. they only penetrate a foot or 2 into the canopy .. so the more of the plant you can expose the better .. because the little lower stuff just ends up being airy popcorn buds.
