DILLIGAFanswered grow question 5 years ago 2Greenfingers3713 I would start preparing to do the switch at the end of this growing week.
During the 1st week to 10 days after the switch the plants will be stretching so they will still need those veg nutes
However once the buds start to form you should change over to bloom nutes and keep an eye on humidity and temp levels . Hope this answered your question Best of luck with your coming Harvest
