Hi Guys
What in your tap water?Try useing distilled water.What kind of nutrs are you useing? If useing a grow/boost/bloom nutrs are you putting the boost in frist?
You could be locking up the nutrs and the plant is takeing up alot of the salts
and locking out the rest.I had some of my girls start to trun yellow.I used
Revive by advanced nutrients and that fixed them.But be sure to mix the boost in the water frist. hope this helps .keep us posted on how it does.
