GrowCNanswered grow question 3 years ago The plant looks good though I do agree that it is on the small side. It looks like your LST is working well with a good number of buds, nicely spaced for light.
I do see a fair bit of open area and I'm not seeing any complete fan leaves.
When did you defoliate? Don't forget that a plant's energy comes from it's leaves. Remove leaves and there is generally less energy for producing buds.
Are you running both of your lights? Measure the light level at the top of your plants and see if you are getting 800 PPFD+. There are several good light measuring apps for cell phones. I really like the "PPFD Meter" app. All the apps need some calibration to be accurate but PPFD Meter was within 10% without calibration. I also like "Lux Light Meter" but it doesn't do the conversion to PPFD so you'll have to do the math manually.
