Hey just a tip I got from a friend... and he told me to tell you this because I was showing him this thread... he's a vet grower and uses leds, so this is what he says:
"If you want to make your own custom panels you need to make sure that your white to blue ratio is more near 2:3 or 1:2 and that the blue to red ratio needs to be more in the 1:3 range. The extra blue is great because it will make your plants stronger and thicker and result in better buds come flowering time but without some extra white bands, or if you can get your hands on some IR or UV stuff and throw a minute amount of those in you'll have a lot better luck for the second half"
I have no idea if it's viable advice but he was basically choking me into telling you that. My panel isn't far off those specs but it's a bit diff, got the notification it's on the way today!
Oh and here's something for your trich question:

From what I've been told, check what you smoke. So check the buds since sometimes the two can have trichomes at different stages.
I'd say from your picture those are just entering the full cloudy stage so it's got some time left.
