Autoflower Blue Dream

My PH issue from last week has now been resolved. I recalibrated my PH meter. The PH from the runoff is 6.5 with 445 TDS. Its pretty clear Im getting closer to harvest. The trichomes are clear to milky. I will harvest when it turns about 20% amber or so. I have not amended the soil throughout the grow. I only added Black Strap Molasses once a week during flowering. Next week I will just water and keep an eye on the Trichomes. The odd thing is that the plant that I almost gave up on during the start of the grow has loads of buds. It really came around. I learned a lot during this grow. I will run another with the 2x2 tent and SF1000 spider farmer. Then I will upgrade to a larger tent and light. Right now Im thinking about a 2x4 tent with a Mar SP3000. However, I really do like the Chilled lights as well. Thanks for reading. Any suggestions with my grow would be deeply appreciated.
