Real Gorilla Seeds

Your plants are looking ok atm, but with the drastic drop in ec the coco appears to not be buffered properly. Calcium, magnesium and iron are likely getting scavenged by the coco, and those deficiencies will probably appear at some point. You can use calmag or, as Fatboy77 does, keep running nutes at the current strength through frequently until the runoff ec is just about equal to the nutes ec that you put in. I'm assuming your meter is in good order. Unbuffered coco contains ion exchange sites where potassium and sodium ions reside. When it is prepared correctly by the coco processor, by washing in calmag, those 3 ions are replaced by what's in the calmag because they have a greater attraction to those ion exchange sites than sodium, potassium and chlorine, which are displaced. You've caught that early so, after doing that, it should tick along as it has been doing without any negative effects..

Should add; orca film has certain luxury feel in it, as for what it is, so not disappointing at all once the money is gone. Purchase once and be done with it for plenty sure, like a phonic trap IMHO.

I'd had my vape 4 days, my mate came around so I thought I'd be sociable and have a spliff with him. I couldn't even get past 3 drags. 

All depends. In my experience some’ll show during veg and some only once in flower - dunno about other folk -  but @ 3 weeks in from seed you’ll be in for a wait. I’ve heard if the stipules cross it’s an indication of a female (or perhaps the other way around I can’t remember) but that’s more than likely bollocks, I’ve never bothered to check. Other than that it’s just a waiting game I guess.
