Unfortunately, 2 ladies have had yellow tips on the new shoots the whole time. The 3rd one looks good. Fertilization is done according to the Athena chart (40%), 3.0 Ec was too high for me. The last hand watering was with Ec 1.7 pH 6.3. Drain was at Ec 1.4 pH 6.2. They've been in the AutoPot with AirDome for 3 days now.
