i have a somango auto that's turning 5 weeks old in two days and showing signs of sulfur def or possibly iron def with yellowing veins that started in the new growth and has moved into the older growth starting from the leaf base. I've read that dilution is anywhere from 1 tsp to 1/2 cup per gallon, 2 tsp seems to be the most popular but how much should I add per gallon of water? She's not very big under 8".
