How about an overall picture so we can see the rest of the plant to judge the healty. There are many times in the life cycle of the plant when one leaf turns yellow only because the plant has used it up and no longer needs it. Ph of 6 in a hydroponic system is fine, 5.2 - 5.5 is more like the target but 6 is not out of the question. When was the last time you did a nutrient change?
Zandor Reviewed by Zandor on . Help with Hydroponic Problem? Hello everyone! My hubby is out of town and left me in charge of the plants.

Please ask me any questions you need to know...I'm very new at this! (The yellowing of the leaves starts Rating: 5
