This problem came up last grow and now this one. I don’t know what it is. I’m using the Caligreen soil mix and am feeding with molasses and liquid seaweed with the occasional compost tea and top dressing. My temps are 75-80 and humidity is around 50-60%. The Northern Lights plants are being affected first and the worst while my chocolate Kush plants are starting to get whatever this is. Someone please help!
That would be nute burn. Dial down the amount of nutes you're giving it and how often you're feeding.
Are you sure? I’m skeptical of it being nute burn because last grow I had the same problem so I eased off the nutrients and my bottom leaves were yellowing and dropping off Sent from my iPhone using Grasscity Forum
Well, it could also be potassium deficiency, but potassium deficiency has more of a pattern to it. This is more the edges of the leaves dying off, which is a dead giveaway of nute burn.
Flushing with properly ph'd water if you're growing in soil like it appears you are. Honestly it's not really THAT bad, I would probably feed properly ph'd water every other feeding which would most likely correct it. Add in a bit of calmag to correct the brown spotting while you're at it.
Unfortunately molasses Is not good for the soil Tar Sent from my iPhone using Tapatalk @ I love growing weed
Just remember, once you correct these problems, the damage won't be repaired, those parts of the leaves are dead, but it will prevent further damage to new growth.
Research it Molasses has very long chemical chain Of sugar Impossible to break down in soil Good luck No molasses, Sent from my iPhone using Tapatalk @ I love growing weed
It was It affects yield Negatively Good luck Sent from my iPhone using Tapatalk @ I love growing weed
I always use mollasses with no ill effects. I flush with it, use powdered mollasses in my supersoil mix, use it for teas, etc. I’ve heard rumors of it being bad but most is speculation or false based on my own observations.
