What size res? What nutes are you using? any additives?

 

I use phosphoric acid in my recirculating res and it stays stable so that isn't the issue. 

 

29c res temp? is not ideal what sized pots are they in? maybe moving over to hand watering mxing up nutes once a day would be best until you get res issues sorted

Looks like brown spot fungus , low temps and high humidity insufficient air flow

Had problem for some time,what's the root system like, nice and white or brown ?

As for the light colour of leaves , bad ph combined with high EC

Didn't you notice something wrong b4 this given that you have been pumping them with nutrients and they still looked pale?

Have you got time to correct , maybe not

Looked at the bottle... It does have phosphoric acid. I know when I add tap water it does rise steadily over 3 days. After that it stabilises. How big is your tote? You are dtw right?

That doesn't look good buzzer. I thought the same, that quick a rise, wonder about the pH down. Organic pH down doesn't seem to hold well. Ph down with phosphoric acid I found the best. Is it organic?

yep that's what I'm thinking too. I might go to hand watering.

 

it's a 20l res using biodiesel nutes and bloom stimulant, they are in 11 litre pots. Upon closer inspection of my res tank I'm seeing a lot of brown slime type crap. I don't know much about what it is or what effect it has on the grow but I'm willing to bet it's the underlying cause of my issues
