Hey Guys,
Anyone hazard a guess at what might be the problem with these clones?
They are at about week 2
Under 4 x 18w fluro's, with a heat pad
In rockwool cubes, in a clone hood.
Feeding is 2 drops superthrive per 500ml plus misting.
You can see in the pics that there is some 'burning', but it doesnt happen at the leaf tips, and it doesnt necessarily happen at the highest part of the plant. They don't receive any nutes until a root breaks through (no nutes yet in the pic). They are taken out of the setup everyday to receive fresh air also.
So it seems that its not light or nute burn. They always seem to make it through this and go on to be ok, but since it started it has virtually doubled rooting time, and new growth is stunted until it gets over this problem. The burning occurs just when the roots are about to break through the grow cubes.
Cheers
