She's been in the coco just at 21 days now. She was germed in the coco and broke ground after about 48 hours. Slow but steady growth since. I am using an unknown coco coir brand I purchased off Amazon. I looked but it really does just say Cocopeat Coco Coir and was shipped in 5 clear plastic bricks with no name brand attached.
For nutes I am using Fox Farms Trio for hydro. After doing more reading around concerning coco-specific nutes I have purchased some Canna A&B and just waiting for it to get here before I switch off of the FF trio.
I'm curious what you guys think regarding it's size for it being 3 weeks old. It seems pretty small in comparison to other grows I've seen on here. I have watered with ph'd distilled water only when the top inch of coco was dry and started nutes at 1/4 strength for the first week and half strength at the start of the 3rd week like the FF guide suggested. She's been steady green the whole time, only slight issue I noticed was some very slight burn on the tips of the lowest hanging leaves once I increased to 1/2 strength nutes. ph has been between 5.5 -6.0 at all times.
I transplanted from a 1L pot to the 3G root pouch a few days ago. She seems to really like it and has introduced lots of new growth since the transition (i also started half strength nutes during this time). I am running about 75% coco mixed with 25% perlite and the bottom 1.5 inch of the root pouch with straight perlite for extra drainage.
She is sitting under 4 45w full spectrum CFL's in aluminum domes with a light fan blowing over her. Very gentle breeze, didn't want to stress her out.
Any feedback welcome, I think she's looking good but concerned with her slow growth. I'm thinking my nameless coco might be the problem. My next grow will be in a good quality well tested coco.
(I know the temp looks a little high at 84 but it will come down to around 78-80 when I turn the fan back on, turned it off for the pics. Also, the pen is in there for reference)
