The plants were ready for their next feeding yesterday, 4 days after transplant. They all looked good and had enough time to adapt to their new pots and light, so I hit them with another 1/2 strength BioThrive but also added 1/2 a teaspoon per gallon of 5-1-1 fish emulsion. I just checked them and the growth just from yesterday is very noticeable. The big Jack grew an inch and is 6" tall, has 6 nodes and two side branches working their second nodes, all at 20 days. The other four are all 5". I'm sure others have seen this kind of rapid growth this early but I personally haven't. I'm using the same methods I always use so can only assume it's the genetics. If so, I'm impressed. If they continue the same growth rates I've had with some other strains over the next 3 weeks, they could end up in the neighborhood of 28". If I they take this feeding well I will probably feed full strength BioThrive next feeding and then hit them with more fish the time after.
