Hi Patillac31 That slight yellowing could be from to much Bloom fertiliser as I can see you using about 5.28 milligrams per litre. I never go above 3.5ml from any fertilisers. If you say your roots are soggy try to regulate you watering scheduleIs in a pattern wet dry cycle normal sigh off to much water staying for to long in the roots system and is an invitation for soggy roots. Lower your Water PH to 6PH. This way you will should keep roots happy and up taking all nutrition properly. If Plastic pot try to make a few holes all around the pot to allow more oxygen in to the root system and this way you will lower chances off to wet roots for to long. And roots will breath better. Add Cannazym if possible this will help your root system stay healthy. This measures should prevent Soggy Roots From soggy roots you get stopped nutrition uptake. And there after yellow leaves. Try lowering you night temperature a little maybe to 21C Hope this helps and good luck with your growth.
