They are hungry! Feed them! Don't sweat the yellow leaves, they won't revert to green, they will fall off. Its not a big deal. More light, denser plant & bud require more nutes. But don't mourn the loss of the sunleaves, there's plenty bud leaf to carry on photosynthesis. They need a little nitrogen @about 1/2 strength. (Your growth food). Then go back to your bloom food & carry on. Remember what Shov said about sometimes they yellow early? That's just an indication they are way ahead of the hps. As buds bulk, they draw stored energy from the sun leaves. The faster the buds bulk, the sooner the sunleaves go. Couldnt be more natural! Clorosis is actually a yellowing due to an iron deficiency. If you had true clorosis (iron deficiency), the tips of calyx & bud leaves would be turning a golden color too, but that is not your problem. You actually have no problem. This is a natural occurrence. I actually wouldn't add any nitrogen, you may end up tasting it in your smoke. But if you really can't stand the thought of yellowing sunleaves, that's the only way you'll prevent more from yellowing. Geeze! You obsess over NATURALLY yellowing leaves more than I did on discovering that third nipple, & having all the hungry stray kittens follow me home! LOL! Just kidding! Hungry kittens have always followed me home! Hahaha! But anyway..... the T5's are just more mature than the hps, so get over it before you develop an ulcer! Just curious. ... if you had a daughter who started developing breast a little early, would you have an aneurysm? So, your plants are GREAT, there is no problem, relax! You're starting to make me think you're OCD!
