I have been trying to grow these two pepper plants since late December 2018 and they started off maybe half the size. After a little i topped both of them which, I believe, stunted there growth for some time. Then they finally started to pickup with new growth. Both are actually 3 plants grown together. Since then i have done much more research on how to grow plants whether alone or in pairs. Back to the main point, i didn't know what was happening since they started getting yellow leaves so i gave them a full spray with epsom salt diluted in water, i maybe did a tables spoon with 12 oz of water. I then believe that they developed mildew on top and bottoms of leaves as they were speckled with white dots. I since used a solution of baking soda, dish soap, and water and drenched the plants for about 2 days. They white dots seem to be gone but the old growth is yellowing and i don't know what else to do. Any and all help will be appreciated please! I am a complete and udder newbie and dont know much if anything at all in regards to peppers.
