Never add water to Nitric Acid

There is a tendency amongst growers to suspect nutritional problems whenever their plants are not looking their best. In most cases the nutrients are not at fault and environmental problems are far more common. However, nutrient problems do of course occur at times and it is important to be able to recognise them. Assuming the grower is supplying the same solution to all his plants, we can ask the following questions to see if the problem relates to nutrition.

Are all the plants (of the same species) affected in the same way?
If not and if for instance you have some plants showing problems while others look fine, then your problem is unlikely to be the nutrient. If you have a greenhouse full of tomatoes however, and they all show the same symptoms, then nutrient problems must be suspected.

If you have a problem that shows up in the foliage, usually as inter-veinal mottling or dead spots or as pale foliage or yellowing in the older growth or the new growth then you probably have a nutrient problem. The commercial grower will need to have an analysis of his main tank to find out what is happening but for the hobby grower the solution is very simple and involves a course of action that should be carried out whenever problems are suspected.
