Strain is iced grapefruit Under 400W MH First grow Soil is MG Water every 4 ish days Starting noticing those brown spots and the bottom leaves r yellow n brown Is that a nute OD or deficiency of some sort ?? Any help would be helpful I'm repoting them in bigger pots tmmrw
So it would be normal for those bottom leave to be yellow n brown ? Cuz the new growth looks good except for the brown spots
Looks like a nute lockout that I had a while back. Mine was due to my water PH. What are you watering with?
i also vote ph problem, causing lockout...soil is either too hot or your water's ph is too high/low. mg usually isnt a good choice for a new grower... it adds in tons of factors to try and troubleshoot with if you have problems. if you have a ph tester you can test the ph of your water, and the runoff water after watering, to get a better idea of whats going on. if it has those fert beads in it then i wouldnt use it at all. if it doesnt have those beads in it, it may be ok, and your water could be the problem...but without the equipment to make sure its a guessing game... its usually much more work than its worth. you are better off getting soil that is known good with mj and not deal with silly problems.
Coco coir is a great medium. I use it and you can see the results I'm getting here: http://forum.grasscity.com/indoor-grow-journals/1187623-sensi-seeds-super-skunk-coco-grow.html
