thanks for both of your advice ive been looking at the biobizz range bloom and grow i currently am only useing the bloom whitch is 2.0 6.0 3.6 and looking at the grow what is 8.0 2.0 6.0 im currently maxing the bloom feed out useing 5 ml per litre of water i am at 7 weeks today ams says it has a 9 week flowering time but we all know this is only a guideline and may even take up to 12 weeks either way i have at least 3 weeks left and im worrying that they wont make it , it does make sence thinking about it that it might be a nitrogen diffecincy the soil has all been used up and the plants are starveing , i know that pk boosters will help but looking at the npk of both the grow and bloom nutrients i think that i need to find a balence between the too i am going to try 4ml of bloom and 1 ml of grow nutes to per litre of water, do you both think this will be ok? it should bring up all the npk and give the plants what they deserve and hopefully reward me with a good yeild
