Been quite busy so backtracking...
I guess the only thing I did was to feed them then added 2 trellis nets because the stretch on these Super Silver Haze plants was expected.
The first trellis at the bottom is to control the lower branches and the second was used to lean the plants so that they wouldn't reach the maximum light distance and to even out the canopy. I am going to need a third one so that I can lean them the opposite direction because they have grown a little.
The following week I will eliminate the use of GHE/Terra Aquatics Micro and only use 9ml of Bloom to 1 gallon of water. The plants are quite green and doesn't look like they have any issues at the moment. The Epsom salt that is added to the coco solution helps keep the plants green as they aren't as dark as the rockwool plants. Maybe that cation exchange stuff that I really need to understand properly.
Even though the rockwool plants are in only 4" cubes I kinda prefer the way it's growing compared to the coco plants. They seem to grow a touch faster and looks like it can make a nice main cola/top because of how there's hardly any side branching unlike the ones in coco. I suspect that it's due to the amount of substrate space for the roots to grow into so a little veg could've helped but they would've been taller if I did. So rockwool is surprisingly my choice for my future grows, especially now that I've been familiarising myself with crop steering and that agriculture in general have practices that cannabis growers need to utilise if they want to maximise and efficiently use the resources needed to grow exponentially grown crops. And that's by monitoring every input and output.
