First place I would start is with the ph. It is way too high for hydro!

Another grower on here (oldmac) likes to keep his aero water at around 5.5ph.
I grow in dwc and keep it in between 5.6-5.8.

Get your ph fixed and check it twice daily at first to see how stable it is.
Give this about a week and you should see some change. :thumbsup:
tikiroom Reviewed by tikiroom on . Brown spots, yellowing These girls have been in a mix of sphagnum moss and perlite and being fed Fox Farm's Grow Big for hydroponics. They have now been in a aeroponic system for a day. Perhaps now they are in the system they will recover but I'm curious to see what you guys think. They are about a month old now. This is my first grow so its been bumpy and they haven't had the best conditions concerning lighting and nutes. Rating: 5
