Rusty brown spots and yellowing leaves

[mrfantastic]

Hi,

I have been all kinds of plants for years but have come accross a problem and i cant find out the cure.

I am using Bio Bizz Allmix compost, Biobizz grow and bloom feeds , and i am using rainwater, the ph is about 6 but i get this problem.

Can anyone help? im really stuck? there are no pests, no mites, i have predatored the lot, i think its a nutrient or ph problem, it occurs on small and large plants.
Too acidic, ? too Alkaline?

help

nothin to do with ph but it couldbe a little higher (6.8) but it looks nute burn flush, and foliar feed at 1/4 strength util it gets healthy then go back to soil feed ing, but if u cant find whats wrong flush as a last resort. becuz it strips the plants of nutrients and after feed at 1/4 strenghth ti ll conditions get better .

you know what it was?

the ph was too high, needs correcting with ph down to about 5.8

then everything was fine

geez, that looks like the worst calcium defficiency i've ever seen! you must have a lockout or toxicity or something.

here's a good link...

i had the same problem, lower ur nutes way down. go with 1/2 str on ur nute's.. rember less is better.. keep a eye on ur ph and ppm..
