what am i missing I give everything from the biobizz series, some problem with leafs has started

Week 7? You will see fade that's a good thing it means you've used up all the nutes and the plant is ripening just like in the fall the leaves change color. They need a good flush and trim and your good to go. In the future you can try more cal mag then what your using now and start giving it to them right away like every water if using LEDs but I'd just put my money on them being done.

Harvest's coming my friend, that's what she's telling ya' :)

She is done growing and you should be entering a harvest window at any time if not already.
