All these charts and pictures are great…but the most important information I got out of all of this may have more to do with your PH levels..

1. PH level is very important, most all the elements have optimum PH level for absorption. The plant will not assimilate the nutrient if the PH level is too low or too high. Keep PH between 6.8 to 7.0 anything under 6.6 can kill off your BIO Filter. Anything over 7.8 your roots wouldn't be able to absorb any of the nutrients.

2. Iron, manganese and zinc are three essential elements that become inaccessible when PH is above 7.8, Hence their may not be a deficiency of one of these minerals, if your PH levels are off.
