Rdwc take 3

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

@Jumpjet34, Lookin good, once those new roots get a bit bigger your growth should speed up hopefully. If the new roots turn brown again maybe try adding a drop or 2 of hydrogen peroxide to your water, it should kill the the bad bacteria.

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

@Jumpjet34, probably the "best" is beneficial bacteria like Great White which is expensive, just find your locally produced equivalent 🚀

@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 ! 🚀
