Strawberry Pie & Gelato

Yes, fabric pots can change things. They are great because it is more difficult to over water in a fabric pot versus a solid pot. The water can drain freely everywhere, evaporation is increased and the roots get more oxygen. You can flush the soil with lots of plain pH adjusted water if you think you went way over on nutes and want to get rid of them quickly. If the yellow tips came on a bit slowly like you are only a bit heavy on nutes I would do normal watering for a week and then resume with a proper nutrient amount.
