:point_right:The plant isn’t looking that great overall. Ive been chasing nutrient issues, and part of dealing with that is trial and error. I have done mostly the later. I was postulating that the issues seen last week were possibly caused by pH imbalance in the lower part of the pot as the pH of run off was 5.3 and lower. So my strategy to mitigate was to do a full volume H2Only irrigation with a 6.2pH to balance the soil. Then I followed with a regular strength Fertigation with a 6.1 pH. I also reduced the strength of the subsequent ferigations in the days that followed. I was also doing partial H2Only irrigation followed by nutrient solution. I did end up getting a more consistent 5.5+ pH for run-off. But I believe that I have starved the plant a bit with the lower overall solution strength. Yesterday I started to see if my assumptions are correct by doing a high volume, 5.9pH, H2Only irrigation, followed by a high volume higher strength nutrient solution (5.8pH @ 1.6EC). For nutrients I use the full line of General Hydroponics Flora series, and use the Drain to waste feed chart, this weeks mixtures were ‘mid-bloom’. The recommended EC range is 1.2-1.6EC. I have gone slightly off recipe by adding extra Cal/mag, Bloom and liquid Kool Bloom. The buds don’t look affected by the nutrient issues at this time. They continue to bulk and grow. I will continue trying the higher EC mix. I will also be doing a high volume pH'd H2Only irrigation followed by normal volume nurtient fertigation.
