Hi there, OK this is a bit of a long story. I've been growing for a few months now without problems, until now. I was about 3 weeks in to veg and light hazy white spots appeared, this then turned into a rusty colour unknown thing that worked its way across the leafs. The middle aged to older leaves. In some cases there were small holes through the leaves. I pruned off all the affected leaves and flushed the system. After a few days the problem slowly started coming back. I'm still holding the plant in veg until i sort this out. The plant has now been vegging for about 6 weeks and in the last week the leaves have gone light yellow, lime green colour and a couple of days ago I've noticed the leaf edges curling up. Please anyone who has seen this before help me out, its terrorising my plant and I'm smoking my self stupid!! :stoned: . I've included photos which cover the whole period up to present day. I'm growing in an NFT system, ph is permanently between 5.8 and 6.2 (obviously I'm aiming for 5.8-6.0. I'm using canna aqua veg, temp is between 70f and 75f and humidity is floating between 55% and 75%. I also recently added canna trace elements to the nutrients but hasn't noticeably done anything. I must confess to not forcing fresh air in or forcing stale air out. I've just got free flowing air through 2 vents (i don't know how much this will affect the plant of if its enough to do this?) All help appreciated.......
