hi guys...i started growing auto flowers about 7 weeks ago.All the leaves that are around the buds that have just started to appear are turning yellow...I am using a product called bio bud to feed them...about 2 to 3 grammes per litre of water once a week..They got caught in a heavy down pour of rain a couple of days ago and there wasnt much sunshine the last 4 or 5 days...Anybody any idea on what my problem might be,
Standard nute burn ...flush 3 times the volume of the pot with ph neutral air temp. water...no nutes until you see a good recovery, autos don't need as much food as photos, as in most cases they are half the size
1: insert Ph meter into a pot of local water 2: read off indicated measure 3: adjust accordingly (add ph up or ph down in dropper form from most grow stores) 4: or don't bother as its soil you are in, and the soil acts as a buffer anyway, so long as your local water is 5.8 ------> 7.2 you are fine anyways
