I have a blower in my completed sealed room. The Co2 is not the issue, however, if you have a large humidfier in there you might be concentrating Ca as it precipitates out of solution in the air and gets deposited back into the buckets via the air pumps. Just a thought.
More importantly, here is a pick of my Bubba in my house. At one point they had the deficiencies we are all talking about, but I seem to have it beat. The aeration in this system is identical 14-20lpm/bucket as is the warehouse. In fact, this system might even have a little more aeration due to the shorter PVC airline runs.
For the longest time I was unable to get a hold of this deficiency as I was being advised not to use
Calmag or to use it at extremely low levels. Since the addition of
Calmag and epsom there has been dramatic improvement, although I was not seeing the same level of improvement at the warehouse. Over the course of 2 weeks I ran 0.8-0.9 EC.
Day 1 H&G base plus 0.25g/gal Epsom.
Day 4 + 0.25ml/gal
Calmag
Day 6+ 0.5 ml/gal
Calmag
Day 9 + H&G .5ml/gallon, 0.25mg/gallon Epsom
At this point the deficiency was no longer progressing.
Day 14 + 0.3ml/gal Epsom
Today, (Day 15) the ladies are eating 50-70ppm a day. Just topped up with H&G ) at 1ml/gal
I was running a similar profile in all of the systems at the warehouse but have been scratching my head since I assumed that both rooms were identical. Then today, I re-oriented my
adjust-a-wings and immediately noticed that the light levels in my warehouse had actually been rather low as light was being thrown away from many of the buckets. Wondering if the low light levels might have been causing a Ca deficiency (seems counter-intuitive)??? Thought this was worth mentioning.
