to add onto my previous answer, If you PPM is down to 450 that's 0.9EC if on the 500sclae, or 0.64EC on the 700 scale. Best to use just EC and fuck PPM, dive the ppm number by the scale your meter uses, Mine uses 500ppm=1EC 1EC is always 1EC on any scale but ppm's are different. I think you need to give it some space for the soil to adapt. Keep adjusting the PH down in the water to aorund 6.4 your leaves are looking like they having some issues with PH flux and could use to extra K. Soil will always balance the mediums PH and it is not as static as hydro grows. Mixing in Peatmos will help keep the PH lower as well as sulphur, its broken down into sulphuric acid and lower mediums PH that way. With all the flushing it might be good to offer a Microbe infusion to help replenish the population. But i feel the roots need some time when they are not soaking wet. Good Luck!

You didn't flush nearly enough... you've still got a lockout because your pH is still much too high. To do a proper flush, you need to run, since you're growing in a 20L pot, 60 liters of pH'd water through her... seriously!! Give her 1/2 strength nutes in the last 2L of water along with 1ml of calmag and let her dry out. The pH WILL come down as long as you do this! Good luck - just keep going!

I have to quote some text writen by m0use a few questions ago. "Thats some tasty looking ‘juicy pussy’ You must be popular will all the boys in town..lol" But for your leave problem, pH is too high. You need to bring it back to 6.5 Now do not give a very low pH to compensate. But instead give some more water with the right pH till 20% runoff for once just to bring the pH from the given solution into the soil. And to flush out the grow nutrients because they contain too much nitrogen. This is the time to step over to bloom nutrients! You plant needs more P and K and less N. Enjoy your grow!
