Please help with my Old Skool NL!

[bingobongo]

This fan is off a Old Skool NL X Early Misty in her 17th day of flowering. I use Fox Farm Ocean Forest w/ Perlite, feed with Fox Farm Big Bloom, (2) 400 HPS Hortilux, 5 Gallon containers, 79 degrees daytime.

My tap water is 8.5 and I bring it down to 6.8 with distilled white vinegar.

Thank you in advance for your help!!

Hey bingo,

THis looks like typical pH lockout... I'm curious as to why you are adjusting the pH of your water. Soil is not like hydro in that you need to adjust the soil not the water.

I also use foxfarm and have great results... my mix is

Oceanforest
handful of perlite (for drainage)
1tbsp dolomite lime per gallon of soil

If I leave out the dolomite I get the same results you're seeing due to the soil pH being off.

Regardless of what you do to your soil you want to PH your water/food solution. 6.8 is a little high. Bring it down to 6.4 to 6.0 at least.

I've watched plants turn yellow and keel over from someone who I was training for a week or so was bringing the PH down to 4.5 to 5 in Sunshine #4 which is loaded with Dolomite. I doubt watering with 6.8 alone would do that to your plant though.

Dolomite PH around 7 btw.

It almost looks like heavy thrip damage? Too blurry to tell if those are shiny spots or little rust spots?

Any more clear pics of the rest of the plant?

8.5 is high for municipal water. Are you on well?

Northern Farmer,
Those are shiny spots, like a silver color, if you will....

Sure its not spidermites?

You need some nitrogen in flower especially at the beginning which big bloom does not have.

Thanks Blackvelvet,
I have some Grow Big left over, good tip, thank you.

Have you looked under the leaf? There could be a horror factory living under there.

i believe that you have mites my friend.
try no pest strips, they sell em at the home depot / lowe's.
they are cheap and highly effective!!
