Right. That tap water, I left it sitting for a day or so, bu now I decided to use Bottled water. With the Epsom salt, I gave it to them twice, in last 12 days. Thats all. Is it enough? My soil is peat moss, spaghnum peat, worm casting,perlite, EC 2.4,pH 6.2-6.6. ammount of added fert to 50l is 2.5l. I'll go through your thread again, see if I can pick something up. And could you please tell me what PM FDD stands for and also what or who shamegame and med card is pls?
