Those are chelated salt based nutrients. They would 100% improve things and arguably be the best option as the chelate will give them a shot of Fe. Iron is a nitrogen fixer and a deficiency will manifest into several deficiencies. The quicker you can get iron into the plant, the quicker it will recover. That being said, the whole point of growing in living soil is to not use these types of chelated salts as some worry it affects the taste etc. That's why I suggested Alga Bloom as it's available immediately buy doesn't contain chelating agents etc. It would be slower than Ionic but you wouldn't be comprising taste etc if that's your thing.DIY.Rik wrote: ↑Sat Feb 19, 2022 1:59 pmI have got some of this:seymore_budz wrote: ↑Sat Feb 19, 2022 1:57 pmI agree, flushing will make them worse. Personally, I'd grab a bottle of Plagron Alga Bloom and get some food in there.
Ionic stuff. Soil bloom and PK etc......
Some might argue adding salts will mess up the microlife but I wouldn't worry about that as it looks like they all left weeks ago
