Hi guys just letting you know I've put the dying plant problems down to the tent as I binned the autos as we're in bad health and too far gone but moved my moby seedlings that were also unhealthy to my old smaller tent and a week later growing lovely now with fresh green new growth so my advice to anyone buy reasonable tents from good hydro store not of the Internet places like eBay as the stress and money it's cost me wasn't worth the cost cutting in the first place. Happy growing
