Yeah, all my plants in my last grow had 11 fingers on their leaves. Otherwise your plants are looking totally salvageable and you should check your ph.
Max# I've seen is 13 points.
Go check your pH. I'll bet it's significantly out of range. You've got micronutrient uptake problems. Plus a few of those plants will want new, larger homes soon.
I just gave someone instructions for that, and his soil pH situation is similar to what yours seems to be, but not as extreme:

Possible zinc-iorn defeciencies?
Possible Magnesium def?
Possible over-fert?
Just a few guesses.
Here's a link to common nute problems...

Rusty Trichome great link. :postgood:
I found the same guide posted on another forum in FAQs.
They didn't even mention the info was borrowed from Greenman.
Not just borrowed copied exactly, photos and all. Just changed background to call it theirs.
Thx Stinky ok i flushed 1 plant last nite with tap water that came out around 9 and the run off came out 7.0. Today I flushed a plant with 7.0 water and the run off was around 6.8....When i started these plants they were in some crappy potting soil, But i recently changed to Sunshine mix wich has dolomite lime wich i think wont allow the ph to go over 7.0 is that correct? So If my ph drops a few points going through the soil should i just start watering and feeding with around a 6.7? So the run off will be around 6.5?
Thx for all the replys Rusty, Chong, Zissou, Weedhound, Sarah, Dread.
6.5 sounds about right
Okay it sounds like you've brought your soil up to about 6.5. Now just keep on top of watering with fert solution that is 6.7-7 and monitoring the runoff to ensure it stays below 6.9.Quote:

Ok didnt water for 3 days and tried a few things....
saturday @ 10pm i gave plant #4 around a liter of 6.7 water and got a run off of 7.1.........
did the same thing to plant #10 and got the same thing.
after conversing with friends etc...i decided to drop ph down more to around 6.0 for plant #8 7.2 run off!!! wtf???
plant # i gave 5.4 ph water to and still came out 7.2
Im using sunshine mix #2
Sun Gro Horticulture | Products | | Mix # 4 Aggregate / LA 4
"on the bag it says its ph balanced..."
sunshine mix i guess isnt actually soil so a soiless medium does this matter? WTF should i do? i have like four bags of black gold should i start using 25% bg and 75% sunshine mix?
or is the run off ok? I just cant understand how the runoff can be so high now matter how acidic I make it....
