To One Concerned Grower To Another My plants are grown outside in the ground and I am having the EXACT same problem. Mine are a little further ahead but still have a good 2 months growing time and I too am really worried about what's going on and how to fix it. Along with the leaves turning yellow and getting brown spots on them, my stems are a dark red/purple colour. From a lot of information from various sources, the yellowing of leaves is a mix of a Sulfur and Iron deficiency. The spots being found could be because of a Manganese deficiency. Also in my case, the dark red/purple stems could be a result of a few deficiencies including Phosphorus, Potassium, Magnesium and finally Nitrogen. The cure, apparently, to all of these problems is to foliar feed the plant (spraying the plant with a fine mist from a spray bottle) with the correct amount of plant food mixed into it. Since I live in Canada, I researched plant food companies specifically made for and in the Country for (hopefully) best results. I have found that in all the different kinds of liquid plant food, the 'All Purpose' or 'Bloom' has the best and highest mix of the nutrients to fix our problem. I am going out tomorrow to buy some liquid plant food and am going to start foliar feeding immediately! I have come to understand that I should see improving results within 4-5 days if this is indeed the problem. I will be sure to post my findings back here!! Good luck with your babies, I know how much it hurts to see them sick and hurting! A Concerned Grower
