I've had thoughts of removing the growth enhancer, however people have been saying my problem is Nitrogen deficiency. Granted, more Nitrogen supplementation doesn't necessarily mean my plants wont have a deficiency of Nitrogen from other underlying issues.
As far as flushing, would you recommend a straight tap water flush at neutral pH or supplement it with CalMag?
With coco it is recomended to add cal mag but i wouldnt use anything to flush the ec down but water. Then add back less nutes.
Can also use a low strength (like 1.0-1.2 ec) (500-600ppm) complete balanced nute to flush with. Flush until runoff ec matches input ec. Just costs more in fertilizer this way. Works faster though as salts attract salts.
