Not familiar with happy frog heard about it but never used it. I mix my own soil with organic kelp,coco,perilite plus i put my old soil into my new mix and let it rest. I keep it in 2 giant totes inside my little greenhouse. Do you have plenty of holes,good drainage in those pots is water running out bottom good? If it has no more nutrients i'd top the soil in the pot can you get a side view of the plant and container? I use bat quano& fish poop liquid diluted into teas. With auto flowers I've found not to fertilize heavy, I may feed only 4x's with nutrients on autos. The rest is good PH'd water & unsulfured molasses. They grow fast if I don't "over love them" Keep up the good work lots to learn here but if you love smokin your own weed like we do this site will give you all the education you need, take it slow. Peace
