I’m about 4 weeks into flowering and many of my leaves are very pale…many but not all have developed dark blotches on the interior of the leaf before the tips would curl up and dry out. I expected some leaves would do this in flower as the plant is shifting resources to the buds but I never expected it to effect so many leaves. It started in the lower leaves but seems to have spread to the upper leaves even to some of the buds. I guessed it was a ph imbalance causing nutrients lockout…possibly mag def?. Many purple stems. So I did a flush but I am just worried that it’s too late. After doing some LST-ing, I am happy that I have many colas but they aren’t fattening up much as of yet and I’m afraid it’s because of whatever is going on with the leaves.
I am growing in soil and have been ph-ing my water to about 6.5 after adding the fox farm big bud nutrient solution and testing the runoff to be in the 6.4-6.8 range. Hope I am not too late!
