You're welcome crabbyback. I was afraid I was getting too pedantic

So anyway, my NorthenLights plant is doing fairly well. I gave it a flush with some FloraKleen (1tsp/gallon, 2 gallons thru 3 gallons of medium) and then left for 2 days. Got back to see that a good number of mid-level large fans had gone yellow. Notyellowing from the bottom at all...seeming like a yellowing from the middle up. A few all yellow, a few still with green veins and areas of the leaf. I quickly gave it the 1qt tap and then FoxFarm ferts till a few ounces of drain. 6.6pH in 6.5 pH out. A few days later the leaf yellowing has not progressed much at all, so I'm thinking I over-did it with the flush...or the flush was not needed at all and actually took too many nutrients from the soil. This plant is at 30 days under 12/12 lighting. Buds have been filling out well despite the leaf issues.

The poor Laughing Buddha appears to be a victim of my past improper use of lime. I can feed it any pH (I've done 6.3 to 6.7) and it always comes out 7.0. The plant is clearly unhappy and I'll probably put it out of it's misery to make room for a new experiment.
