txbudenthusiast;2022168] I might be over watering and that is what could be starting to create those yellow spots.
Yellow spots, Some good photos would be a good thing, and i recomend that you should fill in the trouble shooting form at the bottom of my post, then you should get more help from other members also.:thumbsup:
Here is another question.
If I want to switch to another type of nutrient (or brand) can I just switch it on my next scheduled feeding and cleaning of my reservior? Or do I need to do something different?
If thats what you want to do try it on one plant if possible and see what happens, if you think its going tits up just change back to your other nutes:hippy:
