@CRiSPrGrow, what is best to use as a chelating agent as I am using all organic nutrients?

@Jumpjet34, 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's magnesium deficiency. The plant with the dark green leafs that's N toxicity. the downward pointing leaf tips , that'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:

@CRiSPrGrow, Thankyou What d you think to the other 2 plants?

@KurbinTurbin, even these new roots seem very weak and brittle ..though not brown. And also all 4 plants are very pale lime green?

@KurbinTurbin, hi mate, I have posted a couple of new pics ......roots seem ok at moment .....fingers crossed

@KurbinTurbin,I have sprayed my buckets black now. I'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'm hoping they are just recovering
