hope that helps bro
I feel your pain, i'm having the exact or very similiar problem. I have a thread called "Too much nutes?" describing the same thing. I'm indoors in pots and most thought it was due to ph & small pot size. I repotted to larger pots in fresh soil but think my soil staying too wet could be a contributing factor. Maybe the problem plant is staying wet longer? more soil moist in that hole, less drainage maybe? In my limited experiance i've had plants give me the "claw" after a watering that was too heavy. When you solve the mystery please post, id like to know what the actual cause and fix is. Good luck to you-FTFast_Pine said:Another thing thats weird, is that other plants,,(same strain and all) are doing just fine under the same conditions,,getting the same feedings...Its fuckin weird as hell...
Fast_Pine said:It starts out as rust patches that form in spots(symmetrical down alond each leaf finger at the serrations, and worsens by burning the tip, and working inward...No yellowing just rust and death...Until the whole leaf is crispy and gold.....
Fast_Pine said:After some time and thought,,,im thinkin its a potassium defficiency...
The link above (thanks DBM) leads me to believe some of them are also suffering from a Calcium defficiency..
Going to the shop now to get some dolomitic lime,,,and a organic Potassium suppliment....Do a little testing..
I figure its getting enough Phos, with the guano feedings
