3/15 Update-
Beginning of week 6 flower, day 35 today. I am cautiously optimistic about the final outcome of this grow, about 3 weeks left and things are looking pretty good. Lots of frost on all 4 plants now and starting to stack flowers now. I think some of these flowers are going to be massive (at least to me) with nodes practically on top of nodes. I am also noticing for both Purple Zkittlez and the Crescendo in the back all have very rigid and stiff branching, I think due to the addition of silica in this grow. the Crescendo in the front doesn't seem as stiff and the flowers on here might need additional support, which I have decided I will do with stakes and not the trellis net, which I hate those things. I think 3 of the 4 will support themselves but that fourth one as it stands will likely need some support.
These two strains are suggested by the breeder to finish in 8-9 weeks. My thoughts so far on this are that the Purple Zkittlez and one of the Crescendo plants will finish closer to the 8 week mark where the Crescendo in the front has been showing more of her Sativa roots and I predict she will finish closer to the 9 week mark or even a bit afterward. Time will tell, but those are my predictions.
The flowers are getting more beautiful by the day. I think Ethos got a couple of good strains here, even though the Crescendo is showing a couple different pheno's. Can't wait to see what they do in the last 3 weeks and if they will get any color. I have been keeping the night time temps at around 70F but will start letting that dip into the upper 60's and a bit lower as time for harvest draws near. Shooting for 40% RH now through the end of the grow. Temps are warming up now and the furnace is not working so hard so the RH has gone up in recent days, had to turn the humidifier off and will likely have to run the dehuey if temps continue to climb as we head into Spring.
As far as the nutrients schedule, I am about at the max manufacturer recommended since I started out conservatively and working up. The current schedule has the A and B formulas being reduced as the flower stacker is increased. Following the simple directions with the idea that less is more and also to build up to the recommended doses slowly starting on the low side. So far I have not noticed any nutrient excess and maybe a slight cal/mag def last time I fed. The cal/mag formula is the one that I have been giving the max dose since this was a problem early in this grow because I am using RO water and use LED lights. I have been giving the max dose on feeding Friday and even a bit extra middle of the week, not a lot, just like 1.5 ml per gallon.
Other than that, things are going well and blown away by the beauty of this plant...
