I started using the 4-18-38 when my tomatoes and capsicums began flowering. The plants set noticeably more fruit and the tomatoes developed well without pushing excessive leafy growth. Mixing each pack separately takes a little longer, but the instructions are clear and the sprayer makes application easy.

Very happy with the results so far. I used the 4-18-38 on my citrus, flowering plants and vegetable garden, with the calcium and magnesium applied separately as directed. Flowering has been stronger and the fruiting plants look healthier and more productive.
