post-6239-1141637365_thumb.jpgHi team,

 

I am using an autopot system, dutch master advanced nutes, 250W MH about 3 weeks veging. I did let the pH get to 7 about a week ago but have since brought it down to 6.

 

Anyway, the outside edges of the leaves seem to be curling up and the leaves feel a little dry / brittle. I do not think it is a heat problem (has been cool here) and the light is sar enough away. The globe is new!

 

All help appreciated! Cheers

ffc99...........I did let the pH get to 7 about a week ago but have since brought it down to 6.

 

w....looks like the plant will survive, but imo its the pH fluctuation that has caused those problems i recommend giving it a really good flushing and keeping an eye on your pH from now on

 

wanta's right on. Your plant will cope if you correct PH and stick tighter to your optimal range for your plant.

 

It looks quite healthy - @ 3 weeks it's just groing to fly from now on.

 

goodluck with your grow c99 lol

Thanks guys! I will do better with the pH. I have been using pH down for a while and ran out.

 

I finally realised that I already had a great source of pH 6 water! I have a 1000l fish tank with oscars and drift wood. The drift wood brings the pH down to 6 and this water seems really stable in my nute reservoir.

 

However, the nute solution that does end up surrounding the pots does slowly sneak up. The pots just have perlite in them which I thought did not affect pH. Seems like it does. lol
