Tomato Fertilizer 4-18-38 is a premium, 100% water-soluble fertilizer formulated for the flowering-through-harvest window of fruiting nightshade crops. The low-nitrogen, high-phosphate, very-high-potassium ratio is tuned to fruit development rather than leafy growth, with EDTA-chelated iron, manganese, zinc, and copper plus boron and molybdenum in every bag.

Potassium supports fruit sizing, sugar transport, firmness, and post-harvest quality, while available phosphate supports flowering and fruit set and the controlled 4% nitrogen keeps energy directed toward fruit. It is well suited to tomatoes, peppers, eggplants, tomatillos, and other fruiting nightshades, and dissolves cleanly for soil, container, drip fertigation, hydroponic, and foliar use.

This formula does not contain calcium by design — calcium and phosphate should not be combined in concentrated stock solution, so a separate calcium source should be applied independently for a complete program. Pre-dissolve each fertilizer separately, check pH and EC, and for foliar use, spray in early morning or late afternoon below 85°F. Store sealed and dry.

CDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.

Defective coarseness adjuster
Color: Tall Set - Black White
These salt and pepper shakers are ok. According to the description of the product, you should be able to adjust the coarseness of the salt and pepper added to them, but that was not my case. The coarseness adjuster on the set I received is set to one position and there is no way of changing it. The grinders work well, but if you are looking to adjust the coarseness of your salt and/or pepper look for another grinder set.

Works good but have only tried it on fine setting.
Works good but should have an overall cap as seasoning gathers around the inside.

Best S&P grinder set that I have ever used!
Cute chefs cap! Love that they are glass containers with ceramic grinders. Grinds salt granules and pepper corns very finely in both directions. Excellent purchase! Great value!
