looks to me like it needs a bit of nitrogen (and, possibly a bit needful of some potassium) mixing some wood ashes into the water will supply the potassium, if your ferts don't contain enough ... don't overdo the nitrogen, too much will burn them ... mix your 'Grow' type ferts 1/2 strength, and foliar-feed the plant (spray the leaves with it, particularly the undersides, first thing in the 'morning' while the leaves' pores are opened) ... do that every morning for 3-4 days, and they will probably respond soon after (foliar-feeding is harder to over-do) :smokin:
