if you think your plants has any nutrition shortages, go to www.canna.nl then "grow info" and "info courier" ... there you can browse through the different shortages with pics and get some background information on them, and of course how to solve them (since it's a commercial site, of course they will tell you to use your products, but anything similar from different brands should work as well)
