I'm not new to growing, but always stuck to outdoors . Here in the UK I've kept to Autos as more tolerate to our lower temperatures and unreliable seasons. Currently growing in Coca mix with perlite (70/30) with a slight add of bat guano. Using all hesi fert products with correct NPK , with a small amount of liquid seaweed and sugar molasses. Ph is 6.5 - 7 , with moisture levels slightly higher as was slightly keen on the water front. Night time temperatures are not ideal at averaging at 50*-55* and daytime 70*-75* with minimal of 9 hours direct sunlight. As pictures show , discolouration has occured from week 4 and seemed to have worsened. New growth seems healthy but after time starts to discolour. My first thought was magnesium deficiency, which I have addressed this morning with a mix of Epsom salts direct to the soil (1tblsp / 4ltr) . Would like any other review from fellow growers to see if I have diagnosed this correctly or if there are any other issues to sort Thank you !
Hmmm..standard nute burn! Flush out the coco and no nutes for 24 hours IMO: then feed at 25% less for one month until you get the 'feel' adding slightly more each time you did flush the coco once opened ? as often the packers claim they do ...and in truth never done? good luck
Looks like maybe magnesium deficiency, mine are doing same thing Sent from my iPhone using Grasscity Forum
You should always be feeding coco with calgmag or they will steal it all from the plants Sent from my SM-G950W using Tapatalk
