I have my plants in ten gallon soil pots, I had nutrition lock that got complicated. Finally I decided to flush plain water by five gallons each plant a day ago. They’re drying out now, my question is when do I introduce nutrition and how do I introduce it?
This morning as a tester I put a small cup of 20-20-20 in three of the plants to see how they take it, one teaspoon per gallon strength.
Can you please tell me what I can do better or what I am doing wrong? Is there a specific nutrition deficiency, etc? I need to put some green back into it.
