Ok, so I posted about this a few days ago and then life got in the way - picking it back up now. So I started these seedlings out in 1 gallon pots using promix HPCC - using Jacks 123 fert. Everything was fine / I then transplanted into 3 gallon pots with Ocean forest soil. Using RO water @6.0 pH for feedings. Most of the plants have been doing fine but last weeks started noticing these brown spots / looked like cal-mag to me. I then stated adding 1.25ml of cal mag to my RO water for the last couple of feeding; but I am seeing it profess upwards on some. I took the run off pH on them / and the ones turning had a runoff pH of ~4.2 - which is real low. I know runoff is not the best measurement / I got a soil pH tester coming in today. Based on that I then increased my pH to 6.8 with cal-mag supplemented in my RO and flushed several times until the runoff pH measure >5.2. This was done Sunday night. There are only 3/4 plants doing this - the rest look fine right now. Any suggestions? If I can’t get this under control I am just going to use this plants as mothers and clone off every shoot I can and start over. Thinking about ditching the ocean forest from here on out and going str8 promix HPCC so I can control things better with the JaCks 123. PPM runoff varied from 300-600 - hence I will prob start adding about 25% jacks to the mix (boosting cal-mag by about 15/20%). Thoughts. All other factors (temp, humidity; etc… have been spot on).
