Sudden

Things were looking good then on the beginning of week 6 i saw this. Been using ff nutes at 6.5ph. Water temps 63deg. Its all of the larger leaves and happened rapidly.

I will add this plant is in a bucket that holds a bag and a half of ocean forrest dirt. I water every other day nutes one day ph water the next. No foiler feeding. All under a 1000k hps 18 to 20 inches over the plant. The temps range from 74 to has high as 88.

have u checked your ph run off?

 

[420healee]

Was 6.3 the last time i checked.

this help any

fox farm ocean forest is hot soil and if your adding nutes every other watering you may have salt buildup. check your ppm coming out.

super true ff=salt lol

For a 1000watt hps that's too close I would think. I grow with my 400w 18-24 inches away. Back the light off, for starters

400w should b at 1- 1 1/2 ft a way you must got a hot light

With an air cooled fixture you can get them much closer.

I run my 400watt anywhere from "3 away to "8 away. Depending on how I want to focus the light on the canopy.

That looks like a Ca- to me. Upper leaves, necrotic areas on the veins and/or leaf margins.

nice I got a open wing I could never dream of getting that close

Turned out this is my suspected problem. 5.6. Adjustments made.

You probably water and feed too often and your ph is probably low locking phosphorus

@420healee - I don't think your pH being off by .2 from ideal range should result in such dramatic damage to your leaves. I have to agree with others that you're likely seeing some sort of deficiency. Now, it could be that your deficiency is related to your pH level.

It's not that clear in your pictures, but some of them suggest that the burning is originating at the edges which might mean a potassium deficiency.

Perhaps you're looking at a combination of things.

I agree with @GT21 and others that you're probably feeding too often for FFOF.
