you need a medical record and a medical mj doc to give you a permit to be able to go to the clubs then the clubs give you a id card. alowd up to a pound on you and 12 plants depending on where you live in cali some places have no limit
you need to water rockwool more than every 4 days ... more like every day and possibly twice a day if the plants are growing vigorously and have a large healthy root system.
A 4x4 cube alone is not enough for plants that size, do you have roots dangling out dying? You should have the rockwool on top of another media like hydroton balls or lava rock so the roots can grow down into the other media.
Your plants look like they will all die soon if you don't fix the problem. rockwool can get too much water and then the roots can't breath, that can cause this but also not enough water can cause it too. Might also have root rot if the rockwool was too wet all along.
Is this ebb and flow or drip? Either way you need more media than just a cube.
Watering rockwool every 4 days? Holy fuKK! A cube needs water as much as 3x a day certainly not less than 1x.
Flood and drain 3 times a day for 15 minutes with proper water and nutes...they will rock!!! Rockwool is good stuff, works well for me..your plants will come around..
