i was wondering, my leaves are canoeing, turning yellow, and has some really weird wrinkled up spots on them, but no bugs. anyways, from reading through these forums i feel i have learned a great deal, i figured that they were overfed, and i needed to flush them, should i see results from the flush soon, or is this something that will take alot of time? they are a week into flower. also, i would just like to say THANK YOU!! to all that made cannibus.com what it is, and the people that use it and has very useful information!! THANK YOU EVERYBODY!!!!!!!!

You should also check your run-off ph... best to buy a meter and not mess with the strips. http://boards.cannabis.com/advanced-techniques/169842-any-soil-growers-ph-pen-need-some-help.html <-- there are several examples in this thread :)

If the problem doesn't go away, you can always fill out the troubleshooting form and post some pics in the plant problems section :thumbsup:

Good luck :jointsmile:

Good idea on both counts :thumbsup:

You're growing in soil, right? The ph buffer in your soil may be running out, and causing your ph to drop. I think the canoeing of the leaves is more of a ph issue, while burnt leaf tips is over-fert... but this is really just a stab in the dark without pics and more info... get back to us once you've found out the ph going in and coming out.

yes, i did have some burning and shriveling. :( when i flushed, i just used regular tap water, ph unknown, would it be wise to flush again with corrected ph? what is the recommended ph to grow in? once again, thanx alot!:jointsmile:

As long as it's between 6.0-7.0 you're good (6.4-6.6 being about optimal)... but if you're tap water is 7.0 going in, and your run-off is 6.0, that means your soil is somewhere near 5... which is too acidic. Anyways, you could flush again (same day it's probably ok) or just wait for it to dry out and test the ph again next watering. Don't want to over-water by flushing too many times...
