    Default Is this a mag deficiency?

    Hi I am hoping someone may be able to help. Just done a nute change for the last week of vegging but I started to see browning of the leaves. From a previous post I was told it may be a mag deficiency. My tap water is around 0.4 but I use a Bluelab Truncheon which only shows basic EC. Really struggling to work out the dosage if in fact it is a mag problem. My EC is currently 0.9 as I am using a Rush R-DWC system. Ph is being adjusted to about 5.5. Any thoughts or suggestions would be welcomed. Thanks

    Hi. Is this new damage or old damage? The new growth is looking good. Did you have any large PH fluctuations? It looks like this could be PH fluctuation issue.

    Hi. It started a week ago but my EC and ph were stable at around 5.7. EC was a little high so I was told for the system I use. It is still about the same following a nute change. I have added a little cal mag but am unsure about how much I should add if I am honest

    i would start with half the recommend amount on the bottle and see how she responds.

    Many thanks.

    I have dropped the EC to 0.9 and ph is at 5.9. I have removed the dodgy leaves and they are still looking healthy. I am almost ready to flip, so I guess this will be the acid test!
