Thanks man that's great to know. I'm about done with these damn ferts. From now on I'm just going with blood meal, fish gut water, rock dust, a bit of bat guano and some seaweed tea I made.You would be suprised how well they will grow on very little nutrients. i tried feeding a pot at 300- 400ppm everytime i watered. good looking stuff - great color on all the leaves, Havent even lossed any leaves all the way through now. And not to mention so much easier not having to flush after overdoing it..... the first watering i only did about 150-200ppm. thought i would throw that out there. Sorry to hear about the bad set.
