Its now repotted with lots of perlite aswell (always a good thing)
As for the pH... no idea. Still havent got round to buying a pH meter. Ill probably get one off eBay later on. Yes, they were dry and crisp aswell. Ive been using filtered tapwater for this, and our area has 'hard water' so its quite alkaline. Would it be a good idea to use rainwater and tapwater alternately? It begun when I started using MG ferts, 15-30-15. Could that have been the problem? Before repotting I flushed with plain water.
