6 Weeks Into Flowering And Leaves Are Drying Up And Falling Off Please Help!!!

[MidwestToker]

i have seen this same thing happens to plants that are drying out too much in between watering ,looks like root problem cause basically the roots have died

I'm in coir drain to waste with multiple feeds per day, pots never dry out.

I concur that the roots are dead.

Pathogen is a serious contender and it's always safest to assume an unknown problem might spread.

Did you perform a sulfur burn or spray something on the plants? Some things don't mix well with light.

What is your reservoir/medium temperature? Hot roots = dead roots = dead plants.

Cheers,
