My plants are a little over a montha nd a week old, I have lost half my plants already and would like to not lose these. The leaves on 3 of my plants that I have left are yellowing and I did a little research on other forums and people say its most likely from overwatering. I have them in 1.5 gallon pots and when i water like every 2-3 days I use a half water bottle per plant. Is that too much? Also they say it could be that the P.H. of the water i;m using (tap) is too high or something. Does anyone who has seen there plants yellow and saved them have advice for me to save my plants? What can I do?
