01/Jul/2017: today germinated a Nirvana's Northern Lights, it will be challenging as it will live along the Sweet Cheese auto, so it would require some extra work when it starts flowering. The soil is a professional one with controlled pH, added some perlite and also some humus in the top so will absorbe it with each watering. The humus added lowered the pH but on the down side the EC skyrocketed :(
I grew NL a while back, badly, but the smell after a good cure was like pineapple. really nice.
Are you ppm's accurate? very high for such as small plant. 200-300 ppm would be closer to the mark.
If you under feed your plant, it will take it 3 days to recover, if you over feed your plant, it will take a month. always best to starve your girls and adjust up rather than the other way around.
Good luck. You NL is looking beautiful.
@GH_SOHO, yeah, I also believe the ppm value is high but I don't fertilize with anything (only some humus) so I think (and hope) the ppm values will drop with the followings waterings
