Durban In Chains

Those plants are already showing over feeding symptoms, what would you add more ? The soil is already in an hypertonic condition and your plants are reversing their fluids to dilute the roots zone to turn it back into an hypotonic condition... this is why the tips and the edges are burned ! Plus the 1000w HID at 60 cm they are photoinhibited by getting too much. To give an idea for reference, 60cm this is where I set my 600w HID’s ! So if you really want to add something beneficial for your plants, just add some Enzymes and they will break down all these nutrients in the soil a lil bit faster to make it available for the plant .
