Hm, i know you are in the UK but if you can find a source of good compost that contains both cow or sheep manure AND plant material (not peat though), and mix it with 30% perlite, you are good to go.
stinkyattic Reviewed by stinkyattic on . CalMag and Thrive in bloom... It's my understanding that N should still be fed, albeit in smaller quantities, during bloom but you need to knock it off in the last few weeks. Is this correct? Calmag is rated at 2-0-0 so phasing it out say halfway through bloom would be a good idea? While I'm here, I should also ask if a similar rule exists for hormones a la Superthrive? I hear people mention they use ST all the way until harvest, but I've also picked up that it can actually hinder full errr, fruitilization! :D Rating: 5
