The stretch is amazing! This plant is a real sky king! Buds are really stacking well on most of the branches. A major recovery from the massive defoliation from last week! Internodes are Sativa like. Branchy. BHB 1 is a monster! Around 19 viable bud sites. She's taaall. Lollipopped the lower quadrant for airflow and to redirect the growth where it is needed.
BHB 2 is the shorter, slightly younger plant. Shorter and has about 1-12 bud sites. Five branches are taller than the rest (This is a similar trend in #1).
The buds are looking healthy. I do get the occasional burnt leaf from my heater at night. Another week of stretching and another big defoliation and that problem should have sorted itself out. Just found out my res temp is at 62°F. I've started the circulation fan in my insulated box in sync with my exit fan. When it gets too warm, it'll start not only my exit fan, but also the box fan. Should raise the temp gradually back up to 65°. Where I like it. Still, no one has complained. Growth was/is still vigorous and healthy! Keeping the PPMs at around 800-900. Going to do a straight water flush for 24 hours, then start again at 500 PPMs or so. In soil I've always done periodic flushes throughout the cycle of the plant. Usually twice in veg. Once at around 6 weeks and another at transition. The third is at week four of flower and the last is the obligatory final flush. 24-48 hours after the flushes, there is a strong and vigorous spurt from the plant. three days later 'in soil' I go back to nutrients. DWC requires much less time to do the same thing, so 24 hours, it is! I've done two flushes so far and the experience in DWC is the same. Just faster. I highly recommend trying it if you haven't already.
Although the root rot is essentially gone, I continue to brew my microbe tea using Advanced Nutrients Tarantula. I add a litre every forty eight hours to each plants res. This is just prevention at this point. There is so much peat moss and soil left in the root ball when transplanted from their soil, it just seems prudent. Future grows will be done 'sterile. With no organic material or biosphere (microbes)... unless we run into problems again. With the res temps so low, I don't think it'll be an issue.
