Well, they are still fighting to get better. I flushed with FloraKleen and changed nutes last night:

3 gal RO water = 12 PPM
+ 2ml/gal Zone = 12 PPM
+ 10 ml/gal EJ Microblast = 155 PPM
+ 10 ml/gal CalMag = 545 PPM
+ 16 ml/gal PBP Bloom = 1170 PPM
+ 5 ml/gal Karma = 1245 PPM
+ 5 ml/gal Sweet = 1313 PPM

I then had to add 8 ml total of Up to get PH to 5.8.

When I add the solution to the res there is always a little bit of the Flush remaining (won't drain completely no matter how I do it...) so the final PH ended up at 5.9 and final PPM at 1268.

I checked it today and the PH was at 6.5 and PPM was 1255...:wtf: makes me wonder what is going on with them. I adjusted them back to 5.8 but am perplexed and figure I'll give them another week or two and then they will get axed. By that time the Dominas will have recovered from their recent topping and will be ready for the HPS.

I suspect a PH reading problem with my Hanna pen, so I am comparing side-by-side with a PH test kit (vial/drops) and so far they are correct. It is strange that the Hanna pen sometimes takes a long time to provide a correct reading. I am about to give up on it and order a Milwaukee pen or something similar.
