I’ve been having problems with blossom end rot on tomatoes for years while using things like bone meal with mixed results started this years plants and started seeing problems developing luckily found this product after using for 3 applications over 1 1/2 weeks plants have completely turned around and are now thriving and no end rot and now have a whole lot more flowers appearing while this product must have what the plants needed it’s also more readily absorbed because it’s water based if your tomatoes are just soso get some highly recommend
