Well...Becky... I started going to answer you feeding question.. The next day I was up there with the temperature of the air about 92 *F ..and the little roof deck uncovered sitting at over 150*F... And picking up dead leaves... You likely have already seen it over 90 there... For some time... That's likely the foliage answer... A few minutes needing water... And they are yellow.. I start everyone off with ALOT of dehydrated manure... And continue a bit after planting ... Then I give them other things... Algoflash. For food.. General and flowering types... Spraying with Messenger.. Now called Axiom .. Spray-n- grow. Every few weeks...
