This is a picture of my 5 week old white widow growing in organic soil under 400w MH light. The tips have turned yellow and the new growth on top is yellow. She had her last dose of pure blend 3-1.5-4 12 days ago. It was given at a rate of 1 tsp per gallon. Her soil is a pH of 6.9 and the run-off was a pH 6.5. The problem is just at the top half of the plant. There are no brown spots on the leaves or tips. I'm not sure if this a sulfur or Mn deficiency or a nute burn. I have other WW growing in the same soil mix and had received the same nutes and they are showing no problems. Can anyone offer a suggestion?
