CALLING ALL OLD-HEADS!!!!!

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.

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

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.
