Ive been growing for 3 years now, with a multitude of diffrent plants, with huge success, my rooms do 12 at a time 1 veg 1 flower,
i use 4 600w lights per room using canna pro soil with 20pct perlite,
the problem....
my last crop 2 to 3 weeks into flower started to have red brown spots and yellowing , so i flushed and dropped fert, the problem seemed to continue so i gave them a shot of epsom salts, to no change, by the time of harvest there were no leaves left on the plant only round the buds and a bad yelds were the result,my present crop is now going the same way so i have flushed again but dont wish to go the same way again,
i water only when the potts get lighter,(but not dry) the ph of my tank is 6.3-6.5 my room is 77deg lights on and bout 65 off( not perfect but best i can achieve) humidity is 40- 50,
i have just about read every thread on here, so im not just copping out,
please help , i cant stand to lose another crop,there the only family i have lol

dude at first glance i would say it looks like nute burn, but since your experienced and you know how to flush i guess you would have already addressed that.

maybe ozone damage, since you know your ph is so stable.

check out the plant abuse chart in the faq's if you havent already, that may help

hope all goes well with your family :)

Could it be leaf miners? Tiny little bastards that live IN the leaf.Any outdoor plants in your garden/near your grow area with similar damage?

I think it might be lockout due to Ph...This is like the 5th thread...

You said you keep your Tank at 6.1 to 6.5, this is a good soil Ph, but as it sits the Ph will rise and need to be adjusted before using again.

If i'm way off here, let me know-pros

A big +1 to this one. On my last grow, I had a lot of leaves do exactly what yours are doing now. Unfortunately, I didn't have a pH meter until the very end of the grow. I was pHing my water every time using drops, but was unable to test the pH of my soil/runoff water. At the end, my meter told me that the runoff was running 4.8 off when I put in pH 6.5 water. The problem was that I was using a soil that contained peat moss, which is acidic; and I have read that it tends to become more acidic over time. According to the product description I get about canna pro online:

" Experience the exotic Canna Terra Professional Plus. This special formula comes from the desire to create the purest possible soil mix on earth. The formulation is specifically for indoor, growroom situations. The Professional Plus mix is a more complex blend of peats with added nutrients to aid rapid growth. It has a greater air/water ratio and outstanding drainage properties.
"

Canna professional is peat based. Try checking your runoff water (if possible) and see what kind of soil pH you have. If this is a pH problem, you can correct it from there. In the future, you can mix in a little bit of dolomitic lime with your soil to straighten it out.


I hope this helps.

Looks like septoria cannabina infection. It's a bacterial blight. The only treatment is to spray with Bordeaux mixture which will slow progress of the disease, and allow you to produce at least some crop.

You will need to dispose of all infected plant material, including cuttings taken from infected plants and sterilise the growing area with bleach before restarting.
