heres the set up ...

75cm,75cm ,2mtr bud box
400w air cooled lamp
rvk 100 extractor fan
temps always 21-22 lights out
27-28 lights on
6.5l pots
canadian xpress full nutes
coco
hand fed
now the problem , all through veg and till the 5th week of flower the system ran like a dream like it has done previously. then the ph off my runoff went from 5.8 to 4.8 and 5.1 on my 2 girls .they became pretty well covered in brown spots ( looks just like calcium lockout). ive flushed , ph remains the same the ec isnt far off what goes in (1.8) just a couple of points higher. ive had sciarid fly larvae, treated with nilnat.what the bloody hell is going on with these nutes??its twisting my melon man. thanks in advance

I don't think many people here measure their run off if they're handwatering to waste.

Are you plants looking healthy?
