@TerrazasBrew, Just hit me up if you have any other questions. I used to grow with bottle nutrients for quite some time before switching to dry amendments.

@TerrazasBrew, I also just saw on your diaries that you have already flushed once. What was your EC and NPK ratio of the solution you used to flush your medium?

@TerrazasBrew, Don't hesitate to DM me if you have any other questions. I'm always chilling on GD.

Yes @Hydro_Hiebs, THANKS. I think you help me to discover another mistake. I jumped from veg to floral nutrients on week 4. It was probably too early. First timer rush, the pH from the runoff by then was too low (5) and there was little signs of flowering. I used RODI water for flushing and Rhizotonic to increase the pH. I will follow instructions. I'm still confused with the EC readings and conversions, but the ppm from the flush water was 70 and the pH 7/8. I flushed until the runoff shows 6.2 and 200ppm. THANKS A LOT

@TerrazasBrew, Haven't heard of the nutrients your using but usually synthetic liquid fertilizer such a advanced nutrients or general hydroponics requires the PH to be 5.5 - 6.2. If growing organically with amendments and living soil then the pH should be around 6.2 - 6.8. I honestly thing the yellowing of the leaves and the brown spots tells me you switched to a lower nitrogen and higher phosphorus fertilizer too soon. The cultivar here was still hungry for nitrogen and not really yet for phosphorus. The yellowing looks like lack of nitrogen and possibly calcium if your not using any calcium. And the brown spots come from not being ready for all that phosphorus quite yet in the early stages of flower. Too much phosphorus when they aren't ready for it causes toxicity. If I were you. I'd flush the medium with 3 x the amount of water than medium. Flush with an EC of 1.3 and PH of 5.8 if your nutrients are liquid synthetic ( meaning non-organic). Then let the the soil dry out for 3- 5 days to make sure alot of oxygen goes to the roots. Then after that water with an EC of 1.8 pH 5.8 and watch them come back with explosions. But I'm not you! So do what ever feels right to you :relaxed:

Hi @Hydro_Hiebs, I do have calibration buffer and the pen is always on point. I think the right pH could be 6.2 or less, because the water can leak from the top and mix with the runoff ang give me some extra points (my theory). Do you find the yellowing could be a deficiency due low pH level?
