Thanks dude!

Yes, I've been thinking the same thing. I've been opening my window next to the closet and the temps have mostly been 23-27 lately. I also lowered the plants 1.5cm (changed to a slightly lower bucket to catch run-off) and turned them. The reason I don't think it's heat burn is because it's happening to leaves that are not directly underneath the light also. Very strange, because its mostly in one area and that would imply a hot spot... The fact that the buds are still growing doesn't worry me too much. What I'm starting to think is either over-watering or my nutrients/soil combination is missing some kinds of nutrients.

I like the ideas about the PVC, but it just won't fit this time. I've been planning for my next grow, whenever that will be, to have a bigger grow space so I can fit everything better. I'll have to check out PVC for tubing on my next grow.

Wish I could buy another fan, but the wife's not too keen on buying any more things since we will be leaving the country for about half a year, and my projects will be on hiatus ... hopefully we will be going to holland though :jointsmile:

Thanks for stopping by, I liked the ideas...:thumbsup:

Oh yeah, flushed last monday with 30L water, and just fed them again today for the first time since. I think I will change my watering schedule a little, as this could be another reason for the yellowing. Before I was giving them 2L of water (or water with nutes) every three days, with a water, nutes, nutes schedule. Starting today I will try 1.5L twice a week, with my canna terra flores 2-2-4 on one day and plagron top activator 0-9-10 the other. I'll do this until week 7, then flush, and water if needed for the remaining 1-2 weeks. We'll see what happens...
