thanks for the advice guys! So no one really thinks that they need constant exhaust fan for fresh CO2? I Its exhausting into a much larger room which is about as cold as outside...

Thats what I'm doing but it isn't powerful enough to maintain anything above 14 degrees on a cold night with the exhaust fan on. I've just set the exhaust fan to cycle on and off every 15 minutes while lights are off and we'll see how that goes. I was just worried that I would be starving my...

Yeh those brown leaves are leaves with only a couple of brown spots a week ago - a little worse than what can be seen in pic 3 above. I removed all the obviously brown and useless leaves and left a couple which still looked mostly green last week. PH and EC are getting more and more stable. My...

Cheers mate, I just got a Ubibot which is pretty cool and gives me graphs of my temp and humidity. Trying to use info this to automate temperature with analog socket timers which I already have (on the fan) and a temperature switch which I use on an oil fin heater. Temps get up to about 25 in...

Thanks mate, is it OK to do in flowering as well as veg?

Cheers mate, What do you think I should be looking for before I swap? No more leaf damage? I removed all the dead leaves last week after your advice and the leaves in those pics were mostly green last week... I've been looking at a way to do that but I cant exactly get running water to where...

Hi, The temperature in my grow tent is dropping to about 13 C at night. I've tried to do a bit of reading on ventilation but most articles/books/threads talk about ventilation for the purpose of removing heat where as here I need to conserve heat. Am I right to assume that I can cycle the...

Update: This will be my last week of veg I think. I changed the water today and set EC to 2.0 with CMX (Cal mag) etc. It still looks like some of the leaves still have the same problem but there is a lot of new growth and it has been growing quickly. There is also a lot of new white root mass...

Hey mate, thanks for your input. I have been tracking EC and even during all the problems it hasn't really shifted more than 0.1 in a week. If I remember correctly the problems began around the end of week 2 when EC was only at about 1.2. In my previous grows I have tried to keep the EC down a...

Cheers mate, its looking much better :) so thanks again for your help! Just did a water change (used 1/2 additives), set EC to 1.9 and added some Mammoth P this time as well as Great White. I noticed when I did the water change this time there was a lot less brown sludge covering everything so...

Update: So i used the rest of the heisenberg tea on my last water change. It seems to leave a lot of brown sludge in the res, but i wiped away most of this with paper towel. I may give it a flush with plain water tomorrow before I do my water change. I've also started using half the amount of...

Update: The plant seemed to be doing better for a couple of days after adding the greatwhite to the res last water change, or it could have been because I upgraded my air pump to a 20L/h pump. Lots of new root growth and its gotten a little bigger. However, I made the heisenberg tea (with...

Thanks mate. Strange though, I though Dutch Masters pissed off to the US and discontinued their Gold line in favour of their new Commercial line... Fruitsofnature even seem to have the Add 27 Flower which I was struggling to find 2 years ago. May return to dutch masters on the next grow now that...

Hey guys :) Was wondering if I could get some opinions on some good nutes to use for DWC which can be sourced in AUS? I used to use Dutchmasters Gold which I found to be really good but you cant get them anymore... After I ran out of the dutchmasters I tried the base nutrients and potash plus...

I did not dissolve the greatwhite in warm water before but i'll do that next time. I did add it to water and kind of stirred it before adding it to my res, it looked dissolved but I don't think it was. Is there somewhere I could read up on the nutes you use? Cheers mate

So i executed my plan, flushed the res twice, once with h2o2 then added nutes with some GreatWhite, set the res to 21 celcius and this is the results after about 24 hours: Not sure if its good or bad. There definatelly seems to be something growing on the roots now and the res is the color of...

Update: Bennies arrived a few days ago and I've formed a plan of action. Today im changing the res and running 30L of Water with 5% H2O2 10mL for 3 hours, then plain water for an hour to clear out the H2O2. Then I'm going to add water with nutes along with the great white bennies. Later...

Update: I dont think the H2O2 flush really helped that much. What i did notice is that for the first couple of days after the flush the PH did not drift upwards as aggressively, but no its back to drifting up about .5 a day at least. I've purchased a couple of different bennies but still...

Doing 3 water changes today. 1st and 2nd are 30L of water with 10ml of 5% H2O2 for 3 hours each. 3rd is 20L of slightly weaker nutes with H2O2 and the Dutch Zone. Hopefully this cleans some of the rot out if there is rot. I'll put up some more pics in a couple of days. Also ordered some Great...

Thanks mate, you've been a great help!
