General Cultivation Q&A

Hey guys, got a rdwc 4 bucket system. Ph 5.5, ppms generally 500. Dutch master a and b veg, zone, silica and calmag all at half strength. I'm getting signs of nute burn/calmag deficiency yet that can't be the issue. I had root rot at the start due to high temps but sorted that with a chiller and lots of zone and time. Root mass is pretty much pearly white now and I get plenty of new growth. I only get these issues on older fan leaves. Anyone shed light as to what's happening? http://tapatalk.imageshack.com/v2/14/12/30/a7b58988f10cf7c343766b6da27e61a0.jpghttp://tapatalk.imageshack.com/v2/14/12/30/160092d2fd246bc4d3be823f09b3434d.jpg Thanks in advance guys

Hey guys, HAd a terrible experience with Dr Greenthumb seedbank as advertised in HighTimes - I sent them a cash order before the start of our season, and have been waiting and waiting, I finally contacted them, and was told "we never received you order" - Ok, it happens, so I wait another 2 weeks, and email for an update and was told "we don't have your order, don't ever email here again, and F off!!) To me that is crap! Just because we are half a world away they think they can treat us like that! I think that is rubbish! Without customers, business go under and especially in this industry, where the customers are trusting the company will send them what they order (l…

Hey Fellow growers, hope you all had a merry christmas!! Im still yet to create a proper setup, for now im just going with the flow, but I want to create a system setup, and I have an idea I wanted to run by other users who would have more experience and would be able to let me know if the design would work before I go purchasing all the parts etc. *my main requirement is to have the ability to move my plants from inside at night, to outside in the sun during the day. So one bucket per plant is probably required, as i cant see little 5 foot, 42kg me lifting a large tub full of water with multiple plants. Also important is shut off/ closure valves (I think thats what…

hey guys and girls merry xmas and all that... hey me and the young bloke have put a few in our tent to head up early to give us some smoko 7am till 7pm started to show so do we need to keep them on 12/12.or now theve shown, can we leave them out as the days are getting shorter???? dont want them to try and go bck to veg..

So I am going to be ordering 25 or so seeds via Attitude Seedbank and was just wanting to hear some other people's experiences. I am ordering to the house next door which has no one staying there but still regularly receives mail for at least 4 of the previous tenants so I know thing's being posted to that address is not unusual.

I have just entered into the world of growing, I have successfully germinated 6 outta 8 seeds in a electric propogator. I am using a Mag357 LED and 2 planter boxes in a grow tent, I have hooked up a heater set around 24 c and have used seedling and cloning medium as my growth soil mixed with vermiculite. Also have set my timers at 18/6 light dark have set up a hydrometer and my humidity is sitting round 26% and I guess my only real concern is mildew and mold as LED doesn't give much heat, Any tips would be greatly appreciated.

Im not afraid to admit, maths, ratios, percentages etc where never my forte at school, i was all about the English and Grammar (although my posts dont often show it haha) , and wouldn’t even attend maths, so i know basics, but in terms of the instructions on the back of the Canna Coco A & B nutrients, it has left me thinking...What the f**k .... the instructions: Shake bottle well before use Fill nutrient reservoir with water Add CANNA COCO A & B to the nutrient reservoir with the dilution ratio 1:25 (40 ml A and 40 ml B per 10 litre of water). Add CANNA COCO A to the nutrient reservoir Stir well, then add CANNA Coco B Again, stir well and let mixture stand for so…

Hi there, Im hoping some of you guys can help me out with this question - im growing some White Rhino, im not able to find which actual genetics i have. I'm hoping to find out how much WR normally can be expected to stretch once turned to flower? My previous train (black mamba) would basically triple in size (the sativa in it) within 14 days of turning to flower. I really want to make sure that i will 'fill out' by tent once turned. My black mamba used to be veged until they were about 40cm tall - ending up at around 1.2m. White Rhino has mainly indica and doesnt strch as much i understand. Please can anyone with the experience with WR give me some indicators? I've alr…

Ok this may be a strange question but I'm going to ask it anyway. Today I was talking "shop" with a friend I mentioned about a discussion I read on the forums the other day ( cant remember witch, 2 days without sleep and four hit's in, I think I am doing well just typing) about not harvesting until the third browning. Had not heard of that before so I did the usual and read up on it. So finally here is the question... It is believed that harvesting after the third browning improves the Flavour and Aroma of the smoke but is there an increase or decrease in the THC levels in the main Trichomes? The only reason I ask this is because I was looking at the Trich's on a …
