I don't know which forum post this goes to, but I was wondering if anyone has one and could offer advice? My leaves are yellowing am I putting in too little fertisiler, I don't want to put too much, so put 8ml to two litres as advised. or is there another fertiliser other than the Ikea one i can use? Or I've read Epsom salts can help fix lack of nitrogen is it safe for hydroponics? Seems like a silly question but i don't have a clue haha.

What are you growing? -
I was growing pak choi and spinach, was only 11 weeks and had cut a few of the outer leaves and growth was good then started all yellowing. I also have an experimental 2 strawberry plants to see if it'd work and how it'd work, but I took al the salad leaves out recently, as I thought maybe dying off because they were finished but the strawberries are really yellowing now.Comment

I haven't used one of these but the instructions I found online suggest harvesting at 5-7 weeks, so maybe you left them too long. Perhaps this system is only good for plants that grow quickly and are harvested young.
It does sound like they're not getting enough nutrients. Lack of nitrogen in particular makes plants go yellow. Are you regularly topping up the fertiliser solution? You could experiment with making it a bit stronger, but an overdose of nutrients can be just as bad as not enough.
Epsom salts can fix a lack of magnesium but not a lack of nitrogen.

I'll try the experiment of adding a little more fertiliser. I'm thinking I might be letting it run out too much before adding water as well, thanks.Comment
