my worst looking turnout ever day 34

[domokun]

Hi,

the setup is 4 4x8 tables 60 tops misters w/ 3/4hp flojet pump

nutes are canna aqua i have never ran over 900ppm @ .5 conversion..

there is 3 different strains in the tables.. bchp, and bcbigbud and unknown and unknown and also some smaller plants on another table that are uneffected by this problem...

the bchps seem to be the least affected

im sure my yeilds must be shot now.. hopefully i can still pull off over 1pound per light here anyways here are the pics if anyone knows what this is..

i keep my ph at ranges from 5.3-6.2

Check your PH. If PH is in range, looks like a calcium deficiancy.

i vote for radiant heat... what are the temps?

I'm not the expert but it looks like a good case of brown spot fungus.

Since the plants are flowering and its obvious your growing for more than personal, then just finish the flowering and harvest.

It is too late to fix it. If you were in veg then a good garden fungicide would be ok, BUT NOT NOW!

Try increasing the air circulation and Ventilation.

thats a good guess.. the temps are running abit high about 28 degrees (c) without co2 running right now.. and no air exchange at all... i had some other weird spots like that and i used defender on it in veg and it didnt seem to cure it that well maybe this was that problem magnafied

but the weird thing is the tips burn.. so im thinking its more then a fungus and its a nute problem..

im going to try using 1/4th epsom salts till finish.. i added my pk13/14 also hopefully i still get some sort of yeild

Looks like muti-nutrient blockage.

Stay green!
