The plants are a little more than 2weeks old and they developed yellow leaves with little brown spots on em. Growth has stopped completely, the stem is purple when all my other plants have green stems. This one is still on its second set of leaves while the others are on their 4th. I was using MG all purpose 8-7-6 ferts then i went to the head shop and got other ferts instead. All the other plants love the new stuff but this one hasnt gotten any better. I have no ph meter or anything to measure the amount of nutes, i just follow the directions, it says 2ml of Grow A and 2mls of Grow B in a litre of water. The guys said he uses it without any probs. I cant think of anything else at the moment. Any info or tips would b apreciated. Thanks for the help.
