AN nutes arrived today. Going to swap over each barrel to RO water and switch nutes.
Hows best to do this?...
In regard to how much nutes to give?..
Half strength full strength or try and match ppm to what it is now..
Will be adding rhino then calmag..
Im considering switching the lights back to 12/12 also

Changed the water over to RO last night.
And started using AN
Ph is 5.4
And ppm is 900
One plant is lagging behind and I think the roots are going bad. All other plants have nice healthy white looking roots..
But the one plant has darken roots. They haven't turned to mush or slimy.. so I'm not sure.
Some leaves have what looks to me like burning.. again im unsure.. and the pics don't really show it well..

I think it had started just before tbh.. but just not to the extent they are now and only on the one plant.. now its all of them
The one with root damage? if so that's your answer and I would not add anything yet. What are your water temps and have they changed? Are you running sterile or any kind of beneficial bacteria?

Open each rez and smell. Do they smell different? Or like mildew

Temps should be 20-21 C. Your water temps are a bit to low. Use the sensizym at full strength, I have never used sensizym before but it won't hurt. Can you take pics of the roots closeup.
