Iron fe controls photosynthesis in plants there are two types. you want dtpa iron not edta iron dtpa iron stays bioavailale to to ph 7 + edta iron locks out at 6.5 so unless adjusted your plant may be starved for iron. looks will be light colored leaves followed by dead colored leaves .
As a plant enthusiast, I've learned firsthand how crucial iron is for photosynthesis and overall plant health. Iron comes in different chelated forms, and not all are equally effective depending on your soil's pH level. For example, DTPA iron remains bioavailable in soils with pH levels up to 7, which means plants can absorb it efficiently without risk of deficiency. On the other hand, EDTA iron becomes ineffective above pH 6.5, causing plants to suffer from iron starvation even if iron is present in the soil. When plants lack accessible iron, symptoms first appear as light-colored or chlorotic leaves. This gradual yellowing happens because iron is essential for chlorophyll production, which gives leaves their vibrant green color. If left unaddressed, these leaves may eventually die and turn brown, reducing the plant’s ability to photosynthesize and grow. In my experience, testing your soil’s pH is a key first step before selecting an iron supplement. Adjusting the soil pH or choosing the right chelate form like DTPA iron can prevent iron lockout. Furthermore, foliar feeding with DTPA iron can help boost absorption quickly if deficiency symptoms arise. Regular monitoring and timely treatment help maintain healthy and lush plants, ensuring they receive the iron they need for optimal photosynthesis and growth.
