Since perlite is devoid of available nutrients, the liquid feed applied to hydroponically grown plants is their only source of nutrition. This solution must therefore provide all the essential elements required for healthy growth and development. Moreover, each individual nutrient must be added at a rate which exactly matches its removal by the crop if deficiencies or toxicities are to be avoided. Thus, potassium may be added at a concentration of 400 mg/l, molybdenum at a mere 0.04 mg/l. Yet despite the 10,000-fold difference in concentration, molybdenum is just as important as potassium; without it there would be complete crop failure.

Hmm, i guess i have some basic questions on the fertilizer(s) used in this manner of propagation as well as feeding methods. My questions are; Do we use standardized hydroponic nutrients? Do you water a perlite system from the top or bottom or both?
Hello Im currently new to hydroponics system, I have cherry tomato as a for my experiment . I have notice that the tip of the leaves are already wilting. What may be the cause of this problem?
