Heya guys, Long time browser - first time poster to this great site 
Getting my first ever grow underway using Barney's farm LSD... and running into some problems, i was hoping you guys could help me out before it becomes to big of one
The yellowing is only affecting the lower set of leaves (another reason for thinking it was a def of some sort) but slowly it seems to be creeping higher :\
My setup is a 600watt MH, sadly using MG "organic choice" soil (i know that was a shitty idea) i am using Botanicare nutes (just using the guides on the back for mixing)
My temp is always in the mid 70s (i run 24hour lights)
the only thing that is a bit low is my humidity which is normally in the 20% range.
They got a bit ofa slow start - but just in the last 10 days since adding nutes they have really taken off.
Watering has been every third day (just checking the top few inches to make sure that is nice and dry before watering again) the very starts of the problems were beginning before adding even the first nutes so i tend to not think its nute burn. Nutes began at around 500ppm when they were 3 weeks old - last watering was 1400ppm. Ph of the water is kept at 6.5, though i have not tested runoff.
Any help at all would be great
thanks a ton guys
