Trim the root so it is not deep in the solution. Ph needs to be 5.8 is better. Looks like too much light. If your light is on 100 percent it is too close or turned up too much. Also you need to provide a full diet in right amounts. 2 part and 3 part feeds get all parts always just different amounts.
Your roots are the issue - there must be something wrong with solution - bubbles look ok. You getting root rot whatβs the temperature of the solution
hi, i am a hydro grower too and had the same problems like you.
Leafs became more and more yellow.
Since i raised the humidity above 60% the problem was solved. Keep it between 65-70% in the beginning and temperature around 27-29 degrees celsius.
Hi mate, sorry for not replying via DM but i was blocked and today finally i can write messages under diaries but I'm still not able to text DMs
I see that the recommended use for the Cal Mag you use is 2ml. per liter of solution in hydroponics.
