Striped-looking leaves

[khronik]

I'm thinking this might be a zinc or magnesium deficiency. I've heard these problems are often caused by pH lockout, but my pH was fine last I checked, a few weeks ago. I haven't done anything that would change that. Since this is a very conspicuous-looking problem, I hope someone knows what it is.

This plant is a Satori, and a bunch of my Hashberries have the same problem too. Interestingly, this is my biggest Satori by far, and the only one showing this problem.

its magnesium or potassium, Satori is a tough plant if your feeding it there is something wrong

whats the ferts your using and at what rates
id complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph

I've hardly been fertilizing at all, but I have been following the directions on Jack's Classic fertilizer, made by Peters, when I do. I don't have any pH testing stuff, but I'd be surprised if that's the problem.

There may be some sort of grub munching on the roots of my plants, but I was pretty sure I got rid of that problem. Lower leaves on some of my plants are periodically dying for no reason again, so they may still be around.

I'll try mixing a little epsom salt with my next watering and see if that helps.

Feed it, Satori is a voracious feeder, also this strain also yeilds much better when you top it a couple times

I feed Satori this every other watering:
Vegatative cycle fertilizer
Miracle-Gro® Water Soluble All Purpose Plant Food (they make several fertilizers be sure its this one)

2 level "Teaspoons" per gallon of water, (reduce this by 50% first time application) use this as your water, feed every other watering till flowering

IMO&E MG sux.

peter's is the shit. Where you find? They renamed it hu?

I use Cha Ching at the moment, but would change back to peters toot sweat.

ebay only place to get peters Ive heard.

That's MG, a foliar feed with epsom salts (about 1/4- 1/2 teaspoon/gallon) will fix it, but be sure you aren't locked out, or the problem will recur.

Stinky is right ... magnesium deficiency ... :smokin:

Interestingly, Peters has no magnesium in it, which is weird, because it has everything else. This, combined with the knowledge that cannabis uses more magnesium than most plants, makes me pretty sure it's magnesium. Thanks everyone, for helping! I sprinkled some epsom salt in with the fertilizer when I watered them this morning. Hopefully that'll do it. Meanwhile, leaves are still dying here and there. I'll have to pour some more grub killer on there. Last time I did that, the problem went away for a while.

I got this fertilizer at Adams' Nursery which is like a block from my house. It was like $7 for 8 ounces of it, but that's actually pretty good considering you only use a very small amount of it. The container says a quarter teaspoon per gallon. Apparently they sold the Peters name to Scott, but then Scott discontinued a lot of their products so they started making them again under the name "Jack's Classic." They have a web site that you can order from if you're so inclined: Jack's Classic Plant Food from J.R. Peters, Inc., Fertilizer Manufacturer - Jacks Classic (http://www.jacksclassic.com/)

Actually, I probably could have gotten the fertilizer for cheaper from there, but when you're growing $2000 worth of pot, it hardly makes a difference. ;)

Err, scratch that. I just noticed the $4.99 sticker on my container of Jack's Classic fertilizer. I must have been thinking of the bigger container when I said it cost $7.
