Thanks, Is there an easy way to see the difference between lockout, and under feeding ? the syptoms look similar ?? i think i may have it, but seems strange as my ec is very low ?

I would like to add that the most common cause of Nutrient lockout is pH. This is thankfully easy to fix. The link provides a chart of the nutrients available at different pH. Hope this helps.

[edit] The above chart is for soil, hydro is slightly different.

pH is the most important factor in nutrient availability. If the pH is wrong, it will throw everything else off.



pH for soil - 6.5 to 7
pH for hydro - 5.5 to 6.5

very interesting, thanks !
