Hi,
You should start using your bloom nutrients now when you start flowering but before you give them that you should flush all your plants, which is basically giving them lots of plain water which effectively cleans the soil. Slowly introduce the bloom to the plants with a weak concentration then gradually increase. Flush your plants once every 1 - 2 weeks to stop nutirent build up. Don't use your fert two weeks before harvest, thats when you want to stop and start using plain water otherwise your bud will have chemicals in it from the fertiliser..ew!!

hoppe this helps
Charbud Reviewed by Charbud on . Flowering process Hi Guys Hope you can help me with something. I currently have 14 plants vegging under 1 x 600w light. im on week 3 just now and they are due to start flowering late next week. At the moment im feeding them bio grow / biobizz when needed and my plants have reacted as you would expect.. My question and apologies if this sounds stupid (this is my first crop) next week when I set my lights onto 12/12 do I continue to feed them bio grow or do I have to change the nutrients because im Rating: 5
