does this need to be fed?

[krug]

I`m sure someone else will step in mate. I don`t grow under lights, so i can only comment on my own experiences! If you`re getting stessed, then pm Muddy or jm for advice...they`re rather good at sorting this kind of thing bro!

I think it's lockout due to a ph problem, I've used ffof a lot and it usually can feed up to 4 weeks, personally ive always waited like 4 weeks before adding any nutes at all when using ocean forest they never were hungry so at 18 days they shouldn't be needing nutes from my experience with ocean forest

So if the medium ph is that low and ive been watering with water ph'd to 6.7. What should the water be going in at to raise it?

 

[kushaddict]

Heres some pictures of what it looks like now. Along with some other leaves on the plant that have weird spots. This is like a mystery for me. Help me plz! lol

Yep, it's a pH lockout issue. Feeding at 6.7 and run off at 5.7, the actual soil pH is probably in the high 4s. Unfortunately this is a common problem with OF. You need to add some lime to help buffer the pH.

How do I go about adding the lime? Just sprinkle some on top of soil and water it in?

Oh and when I sprinkle it on top will it be ok to do it before I flush?

 

[kushaddict]

Well I flushed with water ph of 9 until the runoff came up to 6.3. I hope that was good enough. I also put 4 tbs of lime in the 3 gal pot.

This morning there was more spots forming....how long does it take before it gets better? I know itll prob get worse first.

Ok well i corrected the ph but the plant seems to be getting worse. More rust spots and one fan leaf is just turning dark color and getting crispy. You couldnt see it on a picture very well. Im at a loss for what to do now. Im wondering if my flush washed out all the nutes from soil and thats why its not getting better after the ph fix?
