My opinion:

you are over-feeding them by ganging up on your variety of nutrients.. maybe overwatering a little too.

to get more "air" put a couple of fans on them. enough to move the leaves, not enough to blow them off. lol an oscillating fan is great. I usually use clip fans...

miracle grow is ok, just not great. not balanced for this type of plant.

next two times you water, use only water. put your finger in the pot, and if you feel moisture, don't water. if you BARELY feel any coolness, then water.

you should also check the PH of your water before you water your plants, and check the PH of the runoff. this will tell you if your water is ok, or not, annd the runoff will tell you if your soil is too high or not.

for soil, a PH of 5.8 to 6.8 is ok. closer to 5.8 -6.4 is best range. IMO.



oh trimming? I'll pluck an all-yellow leaf if it's in the way of buds. otherwise I pull them when the plant releases them.
