I have transplanted the amnesia haze plants into 4 and 6 inch rock wool cubes. I weighed the blocks and the weights are
6 inch 2566. 30% = 769 so first watering should be at 1797
4 inch 727. 30% = 218 so the first watering should be at 509

I checked the weight of the cubes and the little four inch cubes were ready for water. The larger six inch cubes were still a few hundred grams away from the target dry back. The plants in the six inch cubes did look a little thirsty so I gave them a small amount of water.
The plants in the 4x4x3 cubes have roots popping out already. They are about 6 inches tall and are very close to being topped. I might do a sea of green method for the next run.
Some of the tips of the leaves look burnt but I think this is from the clone stage. The new growth on the plants looks normal. If anymore of the new plant growth starts to look weird I will cut back on the ppm of the nutrient solution.

The tips of the new growth is definitely showing signs of nutrient burn. I have reduced the solution down to 750 ppm. I will continue to keep an eye on the new growth.
