Trouble Shooting Health Problems


Use this chart to help you determine the possible causes for whatever strange problem you seem to be having. Don't forget that your problem may not necessarily be a lack of any particular nutrient, the issue is often availability. High pH can prevent plants from absorbing vital nutrients. Extreme humidity may cause leaves to remain tissue paper thin. Take small steps in your attempts to balance your nutrient solution. It is better to under-feed your plants than to overdose them. Try adding about half of a recommended concentration as you experiment. You can always add more later.
