Hey all!
Read over this thread a couple of time, fantastic resource! Really hoping to get some direction for those that’ve dialled in Barney’s CK, as it seems theres a pretty strong variation in geno/pheno.
Swim initially germinated 10 Barneys CKs in glass of water at 5.8ph - After 72 hours tap-root became clear and were buried. They all sprouted the following 5-6 days. Now since breaking ground it’s been 17 days, and since first germination it’s been 21 days + the 72 hours in the cup.
Have had lights on 24 hours, under a 700watt viparspectra full spectrum LED; As its has 3 dials for intensity of red, white and blue seperately, I’ve red switched off, or usually just on the first percent of being switched on depending on temp; And have the blue on full, with white as high as possible depending on temp again. In regards to temperature have kept it between 22 C (71.6 F) -> 26 C (79 F) with 50% - 60% RH. Substrate in coco coir x perlite 50/50 mix, while there is more then enough air circulating at this point for the small tent they’re in.
Have run canna a+b from day 1, started with 25% but have since reduced to between 15% - 20%. Introduced 4ml per litre of rhizatonic end of first week.
Just have a few questions, and looking for general recommendations
!!
Have Identified probably 3 pheno’s with a photo of each attached, have one that’s bit taller, which was the quickest to pop and develop a tap-root, less leaves though; Also have a second large dense that has overtaken the first pheno’s height with leaf growth; And also have a third that isn’t too happy with something that’s being done as had a couple of these that stunt and die off, and couple that are recovering after they’re first set went a few different colours.
Is the purple along the edges of the leaves, and in the middle of the leaves a cal-mag deficiency? Or is it burn? Anyone running canna for seed start? As love to know if cal-mag is being added in.
Also how is the rate of growth? Does it look slow? On a time frame, so going to have to flip these in 26 days. Any comments on when to flip, does it really matter for these babies? As probably flip the top 6 or 7 to go under 2 x 1200watt Mars Hydro LED with a 400 watt HPS. Estimated output?
Any comment/input would be greatly appreciated <3 
Much love
