Gorilla Girl, Jack Herer x2, Critical OP

finally got my ppm meter I took readings and was shocked to find the Critical Orange Punch had overflow reading at at 2500ppm Big Jack Herer 3500pmm Gorilla 2200ppm Small jack herer was stable at 1200ppm runoff (this was likely because I had an interim full flush before flipping to flower due to a Ca+ deficiency and re-dosed it. The flush probably cleared all the salts accumulated during the veg cycle. It was a good thing I got the meter. I noticed a fair amount of brown leaves shriveling dying below the canopy, which I thought was normal par of the course since they're almost at week 6. I was wrong. I rinsed with several gallons of 1/4 strength nutes and the COP + Jack now have runoff at 1500ppm. Gorilla at 1300ppm. I will dose 1/2 strength today and full strength tomorrow and ensure more runoff to clean the salts out and will keep measuring PPMs The cop is packing on a lot of weight and I think it will be done in 3-4 weeks. Jack and Gorilla likely 4-5 weeks left. Small jack is progressing slowly, I give it 6. enjoy and stay tuned friends
