Zink or iron deficiency ???

Just bought a 8" RVK to upgrade my un-branded intake just waiting for the jubilee clips to turn up then I might be able to close my vent holes without my tent trying to close in on itself, the passive is crazy right now lol gonna hit a better humidity range as I also upgraded my humidifier from a £15 cheapy to a £70 four litre capacity one that can keep a desired setting. Only thing I'm thinking now is my temps will be a lot cooler with this new fan as it is now my top temp was 70F so my 400W heater is next in line I think !

do you have a fan controller to slow down the speed on your outtake fan? If so try turning it down a little to raise temps and lower negative pressure.

ever think of building a pvc frame halfway up the tent to keep the tent pushed out? can also use the frame as a scrog if you add some kind of string.

The pH may be too low for the roots to even take up nutrients, I mean.

Hi Samson, no I don't have a speed controller but after I got the RVK up and running I hope I won't need one. The scrog I will be making my own for my next grow but as of now I'm making do with basics as with scrog I will need other things like lances which I don't have ATM but never thought about scrog and negative pressure. I was watching a u tube clip yesterday how to build one and looks so easy
