quite often we talk of irregular plant growth as a source of pinpointing problems with dosing and nutrient deficiencies. i've looked up several tables and have found quite a number of discrepencies (frustrating) between them. i think it would be very helpful if a chart of some sort was posted. was wondering if you might have something to offer here tom (other than all that indispensible knowledge you carry around in your head)? or does anyone else have one that they find to be very reliable in the course of their experience? i know i would greatly appreciate something like this as a basic reference tool.
