I got a few plants in soil in my closet, which i recently put under a 400W MH. The leaves were very light in color about 2 weeks ago, i thought this was a nitrogen def, so i started feeding with the fertilizer pictured below. A few of the leaf tips started curling, i thought this may have been a Potassium def, and i assumed the fertilizer would fix this also since it has N & K. Since i started feeding, the plants have grown alot and have a much darker green color in the leaves. A week after feeding, the yellow around the leaf edges did not recover, so i guessed that maybe i needed to increase sulfur. so i watered twice in the last week with full strength veg fert with 2 tsp of espom salt per gallon of water. As you can see from the pics, this has not helped either. At this point im confused and now im worried that i may be suffering from a manganese toxicity because some leaves have a few rusty spots. Could i have added too much espom salt? And they have been on 24/0 since birth and i have also been feeding superthrive since birth. Please let me know what you think. Thanks
