Orange/Yellow spots on leaves

You've got a couple of deficiencies here... all caused by two things: the fact that you're using far too much of the BioGrow (causing a nitrogen toxicity which locks out a lot of other nutrients such as calcium and magnesium) and your pH is far too high (you need to get this down to between 6.0 and 6.5). As for the nutes, you should switch the amounts of the BioGrow and BioBloom - i.e., 1ml of the Grow and 2ml of the Bloom - your plants are in flower now and they need far less nitrogen than they needed during veg... BioGrow is going to raise the EC a lot more than the BioBloom so if you're needing to raise the EC with that switch, just add more Bloom to get it where you want it... your plant could use extra P and K as well and this should do that well enough. The damaged leaves will not repair themselves so don't expect to see that... But after a couple of days with the new pH and the new amounts of nutes, you shouldn't see the damage getting worse. Good luck...
