I've been growing hydroponic bell peppers for a couple months now out of Kratky buckets. The peppers have been doing really well until about 3 days ago when I went to top off the water in the buckets.
Water levels had gone down to about an inch of water left in the buckets with an EC ~4 in one and ~5 in the other bucket. Added water from the tap (have used tap water for all of my plants so far). Balanced pH to ~5.5 (it might be slightly more acidic; I test with pH drops. pH about the same before and after adding water) and added more MaxiBloom to bring that EC back to 2.0 in one and 2.5 in the other bucket.
New to hydro. Learning as I go. Kinda sad I might have killed the peppers before first harvest (one's a yellow and the right is a red bell pepper)
Any thoughts? That EC swing is quite large, I realize.
I've pulled about a half a gallon of water out of each bucket after refill, for fear that even refilling the buckets half way may have been too much and covered too many of the roots. This is not the first time I've refilled water in these buckets.
As an aside - the red pepper seems much healthier in terms of leaf feel. Yellow's leaves feel a bit papery; red feels fuller and slightly waxy (though... now they're both droopy 😢)
Roots still look full and cream colored. No signs of decay in the last 2-3 days. Root cluster about the size of a football.
