Any recommended nutrients/supplements that make a difference? I just added on liquid koolbloom and botanicare sweet berry

Check “Nutrients” under the Equipment tab at top of page-

If you are new I would suggest Jacks321. Its formula has been around for ages and it is very cheap and VERY easy to use. When I am not growing organic I use it along with Tribus, ReCharge or MammothP.

What are trying to do with plants, your goal should guide you in supplements.
