Here we have a Beautiful lady (Nirvana seeds - ICE, non fem )
4 and half week into flower
This is just the tip of the iceberg (no pun intended) but all of my women are starting to show this similar problem.
I realise that i should be posting this on the bud hospital thread but its full of idiots wanting a quick solution, plus it is not COCO specific.
Whereas this thread has shit loads of useful info and was one of the reasons i switched to coco in the first place, il post the rest up when i can.
Now my excuses are over please help me to come up with a solution to this darn yellow fever i have amoungst my lower canopy.
As you will see in the close up leaf pics the leaves are yellow with little brown-ish spots dispersed randomly across the surface.
Now before you shout nute burn! nute burn!! ....i have considered this and about a week ago i started to flush (with 10% nutes, instead of the usual 50%)
It has not done all that much so i thought it could be a deficiency of the cal/mag variety? Trouble is i have no idea and need other peoples opinions
SPECS : Straight tap water (no hard water issues here)
House and garden coco A & B (flower....was using H&G coco veg A&B obviously)
H&G bud XL
PH the solution to 5.8
600w HPS
Dont be confused by the layer of sand on the top of the coco, we have flygnats
Done
Peace and good yields
