Just in case you're interested you may find that Potassium Bicarbonate can be used as a PH up and doesn't build salt up in your soil the same way. Lemon juice can also be used as a PH down instead of vinegar, I can't remember the exact reason I chose that over vinegar but I'm sure a quick look around would show why. Hope it helps for the future :thumb:

My ph is about 7.4 I use 2 drops of vinegar to drop it to 5.5 then after mixed feeds it's about 6 and I flux between 6.2 and 6.7

Ah I didn't realise that you were doing coco or hydro :thumb:
 
Scratch that, I thought you were ph'ing to 5.5, I must have missed the rest. Tiredness must be kicking in ;)
 
Thoughts?

Apart from the obvious droop from overwatering what are the temps like in there? It looks as though the plants are either suffering from heat stress with those leaves tacoing (curling into a canoe shape) or you have some PH fluctuation causing it. It doesn't look too extreme but you should check the temps at least :thumb:
 
I'd just see how it goes then Grebs, may just be down to the overwatering if your PH is pretty stable.
