My Very First Cannabis Grow [G1]

So we have fast forwarded here 24 weeks. These regular White Berry seeds were vegetated under 18h 15w full spectrum led and partial daylight for 19 weeks. They were topped at 12 weeks when they reached the light and burned the tops. During this time they were repeatedly left to wilt before overwatering several times (algae on soil surface). They were not fed at all only watered with unfiltered tap water straight out of the tap. As a result of the repeated under watering only 4 plants survived, and they were all basically bare sticks with some foiliage at the top due to leaves going crispy and dying off. At week 19 they were repotted and moved into a grow tent 1.2m x 1.2m x 1.8m. With ventilation and under a budget 600w HPS on 12/12. They preflowered immediately and I think that lasted about a week and a half. Yesterday marked the end if week 5 since moving to 12/12. At week 2 of flowering I forgot to water for a few days and I lost 1 plant and 3 badly wilted. I started feeding with Chempak at week 3 of flowering. So these photos are today, day 1 of week 6 since inducing flowering. I have lightly defoliated twice during flowering. Note that I had mild Thrips infestation for weeks unidentified. I sprayed with Neudorff bug spray yesterday at the end of the light cycle. Today there was no smell, nothing flying, and plants look same. At the moment I think that we're about halfway through week 4 of full flowering. 90% pistils white. Trichomes clear. On that basis I am expecting harvest to be 3-4 weeks from now. The diary will now be properly updated as best I can for the next few weeks. I intend to flush 2 weeks before harvest and cease watering altogether 1 week before harvest. Lastly I am not monitoring CO2, humidity, ph or any of that. I'm being guided by the plants the only symptoms I have seen so far are of Thrips.
