Day 43 of my Short Riders, as you can see ive been having a horrible yellow leaf problem. I tried watering with molasses yesterday for the first time, maybe it will help a little? Does anybody know what I should do to help them make it another 20-30 days until harvest and what I can do to maximize my yield? Thanks!!:eyesmoke:

They will still grow and produce buds, but negative stresses will reduce potency, yield, or both, and these leaves are the sign of a negative stress.

That looks like a severe magnesium deficiency to me. Are you using RO water?

Yes, reverse osmosis distilled water most of the time, sometimes I mix with tap water to even out the pH when using nutes. Why?

I watered with molasses because I heard it is good in the cal/mag category, true?

Normal water has calcium and magnisieum and other trace elements. when you user RO you take all that stuff out but the plant needs it. You should buy some botanicare cal mag and add it in next few waterings. I would add it at 6.5-6.8 ph the first time and use the 10 ml per gallon application instructions. THey should green up really fast and stop that upwards curling. if that doesnt work then do a run off test and figure the ph of your grow medium.
