i know i have asked you guys about this already, but i have flushed twice, 3 gal pots, flushed with 5 gal...sprayed twice with pyrethin, added sweet for the epsom salt. since i am at 5 weeks flowering...what do i do!!!

thanks guys,

Your pH is a touch high.
That's not Mg def, so no epsom salts. Looks like scarring to me. Maybe from old bug damage, but it also looks like K def.
You got a bloom booster or bloom base fert with lots of potassium in it by any chance? I'd do a WEAK foliar with that just in case it IS K def, but also flsuh your soil back down to about 6.7. You are more likely locked out than deficient.
Now grab a magnifying glass and look at the shape of the speckles. A trained eye can pick out the patterns that thrip damage leaves. Do you see lines or trails- even really short ones? Or are the spots just kinda blobby?
Overall leaf appearance says pH lockout to me though.

I strongly concur! :thumbsup: :D

I want to know two things.........

Why did Stinky reply to this title?

Why was this the very first thread I responded to.......HMMMMMM....must have been the title. :D

Oh.......Stealth I come by your thread so PHHHHHHHHHHHHH!

[the image reaper]

old ? :wtf: ... yeah, that's me :( ... ya need some calcium there, I think ... no biggie, not usually a killer ... just add 5ml-10ml/gallon of CalMag+ every other watering, see if the new leaves don't come in OK ... :jointsmile:

ya bunch of old farts :S2:

[stinkyattic]

Lol it happens... when I find myself looking at stuff labelled 'eye cream' and 'deep wrinkle treatment' at the pharmacy, I have to smack myself.

[Weedhound]

And having never been called this before..........we all immediately knew that meant us and came running............:S2:

[SnSstealth]

lmao....well WH, i wanted to make sure the right people answered...and you guys did!!! thanks much...should i add some aluminum sulfate with the cal mag? lower the soil Ph?

[stinkyattic]

No, avoid adding more metals. That's like the fast track to lockouts. Lower the soil pH and you're golden. 6.7 is the middle of the range.

[SnSstealth]

i thought alum. sulf. was for lowering Ph....i get so humbled talking to you guys, lol...thought i knew alot...so how do i lower soil Ph without metals? use Ph down for dro maybe? will fixing my Ph also fix the K and C def? i would think the Ph causing lockout, made those def's correct? cause the FF nutes are all loaded with potash and cal i thought....even with a few years growing, you always learn new shit eh? thanks for bearing with me guys..well, ladies...lol

Unless Stinkster has a better idea I'd use the ph down for hydro if I were you.

[stinkyattic]

Yup, the hydro stuff is what you want. A strong acid such as hydrochloric or even better phosphoric is the most efficient way to lower pH without adding metals, since the cation in these compounds is just hydrogen. Same way you want to use a strong base to lower it, since the anion is -OH and won't interfere with your other ferts.
Hydro up/down is designed for minimal interference with ferts.

sweet! myself and mrs. jack thanks ya'll...

i would also think ph is a lil hi, and now wonder why i also responded with the herd, to the unofficial old fart thread:wtf:

also add the led factor and who knows,?
damm pioneers,LOL:pimp:

[SnSstealth]

lol...thanks rock...i dropped it down, the one plant seems to be behond help, so i may chop her sat...still 46 days flowering though...

Looks to me like it's worse on the older leaves, and seems the pattern of necrosis is too widespread and evenly dispersed to be from bugs. But...?
Did you by chance do a foliar spray at some point, that may have been a bit strong? (mag. sulphate, for instance) Reason I ask is,
I too use the FF line, according to the FF schedule. (local soilless mix, tho) Do you keep the FF recommended schedule? The only time I've had leaves that look like that, was after a foliar with too strong of a mix of mag sulphate. Wasn't quite as damaging as what your leaves show, but was pretty close. After the spray and damage, plant came back around, tho.
I've got to admit, tho...I nute every other watering. On Mondays and Thursdays I feed with 1/2 the strength recommended, so plants get the same ammount of nutes as one weekly feeding. Not sure this makes a difference, but ya never know...

Are your newer leaves showing the same signs, or are they doing ok? Is it the same with all of the plants?
Is this happening to the lower and upper leaves?

ps...I'm not really sure I'm an 'old head', as I prefer to think of myself as being a mature hippy. :jointsmile:

[SnSstealth]

thanks for the imput guys!

yeah...they call for feeding every other watering...we fed the every watering, to see how much they could take...I know Db foliar fed them with some nutes,...i thought that could be it too....I have flushed her 3 times, sprayed her completely with pyrethin twice...gave her cal-mag...she is done...lol, don't know what it was, but she is coming down early....maybe just over-fed an foliar fed too much...i give up...LOL i have never had an issue like this i couldn't fix....so first time for everything....I know not to over feed now, never got a sign of nute burn before the necrosis started though.....fuck it

[Rusty Trichome]

How often do you foliar? And what was happening when you first noticed the damage? Did you keep spraying? Did you change ratios? I'm not an expert, but it looks to me like something externally applied has caused the leaf tissue damage. If this is an internal problem with the plant, wouldn't new growth show the damage as well?

After spraying for bugs, did you rinse the leaves?

[SnSstealth]

i didnt foliar...partner did...not while i was there...but no i didn't rinse after applying the pyrethin...but only 3 of the plants ever showed this coloring...2 dead earlier, this one getting chopped out today.
