"Interesting, wonder why? "................its got nutes in spades! I notice the "metallic" early on with lettuce, but generally goes away as the season progresses...so I figure nutes are the culprit.I did not find this to be a bad taste...but taste in general all of a sudden changes going from store bought to back yard stuff.
A few things to consider:
If you top water , and your pots have A LOT of vents...you will need to fertilize with a solualbe by mid season. I have zero compaction issues with my mix; other causes of "compaction". By mid season every container I have 100% root distrubution to to bottom-this results in soil compaction. This is when I bottom water when possible.Top watering brings the roots to the surface, when roots come to the surface, your plants will start dehydrating fast in heat and sun.I start the season with pot 3/4 full, and start topping up gradually.Mulching the top pine needles, (never wood chips)to prevent sunburning the roots, overheating the soil.With only 6-10 plants, its easer enough to jump from 3-5 gallons to a 7 gallon size. After a season with 25-30 plants in containers-this isn't possible without methamphetamine(no, I'm not serious-so chill your 'torts!).If you use pots with poor drainage- well thats when you will see compaction due to water settling as the water "sits" in the pots much longer-the longer the water sits in the pots ,the longer gravity works on things-sitting water in hi nute evirons will result in root damage-as will just plain old sitting water.Hydroponic solution are areated to prevent suffocation.
The moisture control will counter this (lots of pots DO NOT have enough drainage, adequate for survival but not compared to "open" soil in the ground)by retaining moisture- NOT BY HOLDING ACTUAL SITTING VOLUMES OF WATER.The caps are for emphasis-not"screaming"
.Most of my issues usually result from not enough thorough investigation , its easy to say something sucks because "A", BUT WHEN YOU really CONSIDER A,B,C,D and Me- usually the answer is a combination of factors.
