Don't Over fertilize.
Fertilize after first 2 spiked leaves appear follow the label. DON'T FERTILIZE EVERY TIME YOU WATER!!!
Start with 25% and work your way up!
Leach the plants with lots of pure water every 2-4 weeks. Organic growing is recommended. Its tastes better and burns much better.
If the leaves suddenly twist or fold under, Leach and Spray with pure water for several days!
