That's actually only about half of what they recommend as a weak strength, however I've learned with regular nutes it's best to give a small amount rather than alot.

But I suppose, it's organic so it might be safe to go to a higher concentration?
mountainman Reviewed by mountainman on . brown tips, light burn? Ok, new grow, browning leaf tips, is the light too close? Just the clones are doing this, they do have roots already. mS is under .90 (my water has a base mS of about .25). It is the old growth that is yellowing, and for the time being the new leaves seem to be coming in fine, but time will tell. Rating: 5
