Need help with Auto white widows day 47

I'm growing 2 auto white widows and two Purple Kush in DWC . The Purple Kush plants were planted 10days behind WW from seed. My problem is my white widows bud sites don't appear to be forming. There are bud sites all over showing long white hairs out of the pistols but they have been for about 2 weeks with no real bud formations.
Using:
Floraduo A/B
Cal-Mag
Just started:
Koolbloom
Diamond Nectar 7 days ago
PPM: 879
PH : 5.8
Any advice or thoughts would me much appreciated, these bad boys should be starting to blow up with buds the seedbank said they should finish 60-65 days and I'm on day 47!

 

I'm using 240 suntech LED with two 27w LED bulbs for a little extra lumen action in there..

 

I checked yours out and your buds we're more formed than mine. Granted my plants are bigger just a little concerned do to the lack of any considerable bud formations...

 

I have switched to flowering nutrients. Thinking about getting a 150w UFO LED only problem I have is space, the tallest plants peak is about 4 inches from top of my tent.

 

Yea it's hard to control the conditions outdoors but looks like some good smoke bro!
