If you don't know your pH, its hard to say what the problem might be. You must know the pH of your soil and/or the runoff to grow quality cannabis.

if they are lightning up then it may be a nitrogen deficiency. Then again like said above, it's hard to tell without knowing your PH

[overdose42024]

ph level of water is 7.0

[Italiano715]

bring it down to around 6.3-6.6 if possible. Go to walmart and get some PH down. Add a drop to a gallon and that should bring it down to that range. My tap runs about 7.0-7.2 and I just added a drop to my gallon jugs and it brought it right to 6.6. Also remember your runoff will more than likely drop your PH some. I think I read somewhere it drops about 0.3. Not sure how credible that is though.
