regarding TKO's pictures: the damage does seem to be pest much more than virus, in my eyes. not evenly distributed. i'm guessing by the structure these are recently rooted large cuttings. "duds" plants would never root at this size, in my experience. cannabis-loving variants of downey...

i had trouble with finding pests that needed heavy magnification, or weren't obvious. even with a quality scope, like a stereoscope, i never managed to get a positive id on typical samples. but i did learn a trick: put leaf, stem or stump samples into decent quality ziplock baggies, sealed...

mildew or another fungal issue

do you know anyone firsthand who is growing out these same cuts with better luck? to me, this is the most likely source of the problem. my advice: heat treatments aspirin new quarantined stock, from seed. another location if you can.. i feel your pain. like other posters have said, if...

you say you shut down for 2 months, did you start back up using the same stock?

definitely spider mites. you can use organics and horiticultural oils to make it through the run but unless you want to invest in some serious pesticides, i recommend tossing everything and starting fresh from seed. bleach and heat treat room + equipment. alternatively you can invest in...

did you figure out the damping off issue that you posted about a few months back?

i guarantee this is an issue that came with the cut.

lots of options on amazon and ebay. the gaskets on the cheaper ones seem to rot/crack pretty quick with exposure to bleach. but that doesnt make them leak.

dang, lost a large edit to my last post! what i mean to say is, have you grown successfully in dwc with this strain before? the some dying-some pearly white & fishboning root thing looks a lot like what i've had before. i really don't think it's caused by pythium. the guy i got the cut from...

how did you get these plants to start? clones?

use bulkheads. it's difficult to get perfectly round holes for the uniseals, and the buckets seem much more prone to splitting over time (from the hole) vs. bulkheads. the container material makes a big difference in success and failure with them i've learned. tips for uniseals: -using a...

sadly i'm also feeling like a member of the club here. have had GG since late '14, it was a stellar & near automatic performer for a year and a half. after going to fully sealed rooms, i had a few whoppers with GG, and then things started going down hill. i had several monocrops that were...

anyone have any idea about this spotting? i found several leaves with tiny patches like this and ended up spending hours scoping fan after fan after fan leaf. the buds themselves look fairly developed, not sure what day you're in. could be early maturation; could be that they get...

i know it's going against the consensus here but, here's my experience. i store my RO water in 275s and the temps can vary some. 60-80. can't say this has ever caused an issue. i recently had a period of 60f type weather (followed by 10-20f), so i started my seasonal changeover a little...

http://www.angelfire.com/cantina/fourtwenty/articles/premixppm3b.zip i forgot there was a java version. that's a spreadsheet that lets you do up to 7 at once.

DR.GT., i mainly use it later in flower trying to supplement Mg & S without using more bloom component. how much you should use is hard to answer, start with a little. i.e., 1g per 10-20 gal. but really it depends on what your overall EC is and what your profile looks like. i shake it up in a...

t-bone, on mine what i do is 1st go under the 'guaranteed analysis' tab and fill in all the stuff. then go under 'solution mix' tab and it will display it all for you so you don't have to manually add it up. the other variable is the weight of the solution. weigh 100ml and take 1/100th of...

i use rdwcs, modeled somewhat like the UC setups but i don't have a 'reservoir' like in the UC systems. i call it my rez but you guys call them an 'epi'. also, my pump doesn't pump thru my chiller, 1/2hp arctica chiller cools a master cooling reservoir (chest freezer) which has little pumps...
