I have been useing blumats which are fantastic and H&G drip clean at 1ml per 10ltrs, I chew the buds to get high and sometimes smoke them. The smoke seems ok but when chewing them I am getting a slight detergent after taste, can only be from the drip clean. I just thought I would mention it as smoking it cant be that good for you. I will not be useing it again. Tangwena

Hi everyone, its getting to that time of year for harvest and my outdoor plants are looking ripe, iv started flushing them for the last week or so instead of feeding them and they have started to go a shade of purple on both the buds and stems, this occurred at the beginning of my grow as well before i started feeding them they showed a lot of sigs of purple discolouration along the stems mainly but now it seems to have spread to the buds. Is this a natural occurrence because i have halted the feeding process? should i just keep flushing them for the next week or so? thanks fdl

Im in the first month of summer where i am and one of my sativas, about 4 or 5 feet tall atm is showing signs of some nutrient deficiency im assuming. New growth is yellowing, top large fan leaves are starting twist around. I gave it a rich liquid solution with most nutrients. And some blood and bone. its down near the creek and i think i forgot to put manure in the bed of that plant... Will it recover ok? It still appears pretty healthy for most of the plant. not too far gone. It was fine about a a week ago Will it affect yield??
