Hello well for starters your PH is to low should be 6.1 so prob nute lock out and 1000ppm sounds a bit much you wont get nute burn if the plant is not taking up its food which is what it looks like to me and it looks like its sitting in its run off which is not good for the roots and will fck things right up
