I'm tighter than a ducks arse when it comes to paying for and using nutes..
i know the npk ratios are roughly 3n : 2p: 1k then flip lights onto 12/12 and give 2n: 3p: 2k and then finally n1: p2: k3.
i only feed with every other watering and even then if the girls look happy i leave the feed until i water next time...i'm paranoid of over fertilising and over watering it's cost me dearly on other grows, if i find i have a plant stop developing/growing its usually over watering so i pull the whole plant complete with pot shaped roots out and wrap it in a large cotton dust sheet, stand it overnight and capillary action draws a majority of the excess moisture away..pop it back in the pot, i use sea weed and molasses in every other feed, its great stress prevention
for the plants..anyway i was saying how miserly i am..... a 1lire grow bloom and top max cost 32 quid and i can squeeeeeze 3 grows with 8 plants in each out of them D
