I had actually been feeding 100% of the time until this last time because I had been reading that giving it a break was a good idea. Well, I just watered this last time and it caused issues. A lot of yellowing real quick. I guess because it was used to the nutes and carbs for so long. I should have just stuck with my original plan. The only drawback of always feeding though is that my leaves stayed pretty green all the way through instead of the normal yellowing so it became more of a cloraphyl (sp?) issue in the last stages.
