<span class="link_user">@CRiSPrGrow</span>, what is best to use as a chelating agent as I am using all organic nutrients?

<span class="link_user">@Jumpjet34</span>, hey actually i see many of the same problems , hope you dont mind if i show you something ? like the yellowing on the edges of the leafs and the yellowing between the veins of the leafs that&#039;s magnesium deficiency. The plant with the dark green leafs that&#039;s N toxicity. the downward pointing leaf tips , that&#039;s root problems due to lack of chelation agents. Easy to fix these issues : add cal mag and a chelation agent. Always need three things in hydro : NPK, calmag and chelation agent... keep it simple but you do need all three ! great pH management so far though ! hope this helps ! :rocket:

<span class="link_user">@CRiSPrGrow</span>, Thankyou What d you think to the other 2 plants?

<span class="link_user">@KurbinTurbin</span>, even these new roots seem very weak and brittle ..though not brown. And also all 4 plants are very pale lime green?

<span class="link_user">@KurbinTurbin</span>, hi mate, I have posted a couple of new pics ......roots seem ok at moment .....fingers crossed

<span class="link_user">@KurbinTurbin</span>,I have sprayed my buckets black now. I&#039;m only using low strength grow nutes .... I trimmed back the rotten dead roots and now have new white roots showing and now signs of algae at all......growth up top is slow though.....but I&#039;m hoping they are just recovering
