4 total ingredients that need to come down and there are 6 dispensers that could potentially spit out the ingredients. You have 3 striped candies frozen at the bottom between the 2 cannons and 3 hit blocks. Towards the top, you have 2 hit blocks, a couple of frozen horizontal striped candies and 3 locked in pieces on each side. You need to break into the sides to get some more pieces flowing and break down to the bottom to get the cannons firing. Try to make your way out and down as fast as you can until you finally make enough room to shoot the cannons off. Once you get there, you should have clear sailing.
For those of you that can’t complete Candy Crush Level 390 have a look at the vid below:

Break the lighter cream blocks and work on the heavier blocks surrounding the cannons. Striped/wrapped combos are great for the heavy blocks and removing the cannon pieces. (Vertically striped candy matches will also remove cannon pieces.) Work on the cannons separately to take advantage of the board clearing twice.
