Like nothing I have seen

[Lebniis]

I have never seen this problem before, or at least in this form. I looked all over this site no relief.

I have an OG kush, only a week or two old, rooted in rockwool and then put in Foxfarm Oceanforest. The leaves are browning near where the fingers come together, From outer edge inwards. It is pretty far from my 600watt MH. I am watering with the PH around 6.0, thats the best I can do for now. Haven't added any nutrients or additives yet. Even the newer leaves are having the same thing happen.

looks like calcium def to me.
usualy its more pronounced on the farther edges but i suppose the symtom is the same.
i bet your using RO ur ph also seams a tad high u shoot for 5.3-5.8 for my FFOF grows.(fox)

Yup... you've got some nute lockouts, and right now only a couple are showing themselves. The leaf tips look to be changing color and stems are already purple, which might be strain related unless you see other stems that are green.

Is this in hydro or soil? If soil you need to get that pH up to 6.5 and in a hurry... if hydro then ya may need to change the rez, redo the nutes and reset the pH.

I imagine if nothing is done, you'll see some serious def's within the next week.

I am using Fox Farm oceanforest (soil). You both are saying contradicting things. Raise or lower the PH? I guess I could flush it.

Digital was assuming you were in hydro.... Here's the pH chart, and since you are in soil you should be following the right side...and 6.5 is what you're wanting to see.

I would also recommend adding some nutes to try and stop the yellowing....

thanks for the help. I flushed the plant. in the next couple days I will give a dose of nutrients. thanks for the help.

Hot spot heat burn?
Those edges are way to regular and uniform for a nute defic. Also, really strange place for a nute defic to show up in such a small, inner, uniform area.
The localization of it is the clue to whatever it is.

I think it was Nute lock out. I flushed the OG and one of my other plants. I altered the PH. Tried to raise it the best I could. The plants seem to be doing really well after a little fertilizer and a good dose of water. Thanks a lot for your guys' help.
