Plants, 4 weeks bloom pics: Good or not?

Just wanted to post a couple pictures of my plants. The strain are Sour Diesel, Delirium and Spicy White Devil. They haven't been topped or anything, just straight grow. They are just just starting its 5th week of flower and I just wanted to hear your opinions? Are they going good are are they a little small? How can I improve? Any advice on growing future harvests?

I'm just worried the buds might be a bit small for 4 weeks of flowering. What do you think?

Here is my grow specs to date and how the were grew:
I bought my seeds from Castle Seeds. So far, I have had 100% germination rate. Also, they are feminized seeds.
Start out with a RootRiot germination kit with a 6 inch humidity dome.
I've use Humboldt Nutrients Grow, Micro, Bloom, White Widow, Big Up Powder, Humboldt County's Own Crystal Burst. Following the Humboldt Nutrients Basic Conventional
3-Part Program with the added Crystal Burst. Given nutrients once every 7 days with a light to mid plain watering in between. Once a month I skipped the watering to dry it out
more and once a month I overwatered to fully saturate the soil to the bottom and to flush. My nutrient/water solution's PH was always between 6.0 and 6.5, unknown PPM I
didn't get that meter yet.
Seedlings for 3 weeks (plain water).
I veg'ed for about 7-7 1/2 weeks at 18 hours light.
Used premium bottled RO water, no tap at all, Alhambra.
I am using 180 watt LED UFOs. One designed for veg and one designed for bloom. Which I will be upgrading to a California Lightworks SolorStorm 400 Watt w/UVB LED soon.
48x48x70 grow tent. 6 in inline fan. Always have at least one of my intake ducting to an outside air source.
I used 3 gal. pots until they reached around 2 1/2 feet I transplanted to 5 gal pots.
I used Humboldt Nutrients soil.
The Sour Diesel are about 4- 4 1/4 feet tall and the others are about 3-3 1/2 feet fall.

I don't know what else to add so if there is anything you need to know, ask and I will tell you. Thanks for your input everyone.
