can anyone tell by looking at this leaf what the fuck is going on?

I phrase the subject that way b\c my rooms are a hodgepdge of different shit, but they all have in common that they are soil (well, a mix of happy frog and pro mix with some rock dust thrown in) and I am using the fox farm 3 part schedule.

This problem seems to start as brown or light brown patches, then turns to this, then eventually, the whole leaf is crispy and dark brown.


this problem seems to start really really small, sometimes in veg, but doesn't get bad until mid flowering, then I am racing it to harvest every fuckin time.


any ideas? 100_2606.jpg100_2603.jpg100_2604.jpg100_2605.jpg


I have a not too large budget for gear, but there is something to work with. I have not been Phing my nutes, the test kit I have becomes useless when I add some of the things I add, and the cheap Ph meter I bought is garbage.

Please help a brother out, and thanks

(6). now, i went to cannas canna vega, and gp's flora nova; both one partrers. you neeed to get a good ph meter. i had the probe. what a joke. now i have the canna ph and ppm meteres. digital. u callibrate em time to time, with the 7.01 and 4.1 solutions. most ph soils are cool. normally, with the use of good soil, and water, ph in soil is usually not an big issue.

thx for the reply. I cant seem to find any meters made by a company called canna...?
