Sorry for the delay yall, been havin computer problems. Anybody ever had their screen go so dim its almost blank but everything still work fine? The screen looks totally black but if you look real close at an angle you can see the desktop and everything so other than not bein able ta see shit its workin great! Any ideas???
Anywhoo I recently found out some very interesting info concearning my PPM jumps. I was kickin it with my buddy and discussing the issue, he owns a local grow shop and is a AN guru! He said he'd never seen anything like it and he's been usin AN since they came out and answers shit tons of questions about em for customers on a regular basis. He was stumped until I mentioned flushing w/
Clearex. He claims that if your using AN exclusively there is absolutely no need ta do weekly/biweekly flushes or any at all except for in the final week. Supposedly something about the way theyre made prevents any major buildups in the medium. Im kinda skeptical but he feeds at over 1500 PPMs using the same recipe and gets amazing results every trip.
He says that even tho theres no need,there's nothing wrong with flushing w/plain water its the
Clearex thats causing my PPMs ta rise. Its got chelating agents in it that are designed to not only remove any salts from the medium but to also block the uptake of any further nutrients that are introduced into the medium. Supposedly they can remain in the medium for awhile and block the uptake of nutrients well after the flush is done. So basically my girls are drinking water and leaving behind the nutes, causing my PPMs ta go up more and more after every feeding. And after reading up a little on
Clearex it does make sense, but they recommend using it in hydro once every one ta two res changes so I dont know what the hell ta think!
He said that after a few days the chelating agents should wash out and the PPMs should stop rising. I changed my res Tuesday and set my PPMs to about 1300. The next day everything was fine and then I checked today... my PPMs are at freakin 1650!!! So obviously nutrients are still being blocked from absorbtion by the roots and unfortunately Im at a point in the flowering cycle where nutrient uptake is supposed ta be at its peak! This is getting extremely frustrating but Im gonna water down the res to 1300 again and see what happens, Ill keep you guys posted.
Whats up Malachi, I think I read that same thread about using silicates past week 3 and dude def makes some good points. Its on the farm right? Anyway the recipe suggests using the Rhino Skin in weeks 1-6, but they might just be tryin ta get you ta use as much of it as possible so you have ta buy more sooner ya know! But it does seem like stalks keep thickening up past week 3, if the plant is focusing mostly on flower development that might be even more of a good reason ta use something ta help strengthen the stalks. Supposedly the silicates and some other things in Rhino Skin help increase the flow of nutrients thru the stems as well which def isnt a bad thing ta have goin on after week 3.
But as far as the bleaching goes Ive officially confirmed thats whats causing the yellowing and not a deficiency. Since that
Gavita is so much brighter than the Horti I decided ta switch sides every two weeks. Since I did this the upper leaves on the side that the
Gavita is now on have started to show slight signs of yellowing just like the other side did directly under the bulb. So I raised the lights a lil bit and that should solve the problem.
But I hope your right about the 24 zips man, Id be extremely pleased! But if this PPM crap keeps goin on and slowing the uptake of nutes its gonna kill my yield!
You know what I was just thinkin that Ive added PH down since changin the res, that does change your PPMs right??? If that is responsible for the increase do you still count the PPMs caused by the PH down when judging how strong your nutes are? If my plants react well to 1300 PPMs and I add 300 PPMs of PH down, making the PPMs 1600, that wont cause overfeeding right since 300 of the PPMs arent from nutrients??? Never thought about this one!
