What substrate? And what amendments ? No runoff? And no added nutes other than the soil additives? Do you know ppm of your tap? And last what made ya feed the epsom ?I'm on day 29 with this photoperiod Gorilla Zkittlez and these issues seem to be getting worse each day.
Planted in a soil substrate with dry ammendments, watered with dechlorinated tap water with Epsom Salt. I've watered her twice, 500ml once the soil is dry to 2 inches below the surface. Last watering was on the 31/10/21.
Temperature of the tent varies between 22 to 27c, average RH has been 50% but recently upped to 70%. Light is supplied by a 100w quantum led panel. LUX was at approximately 25k, but I recently reduced this to 18k.
The older leaves developed brown spots/mottling and dry up to a crisp. Mainly affecting the tips and edges, spreading towards the veins and base of the leaf. As its progressing, the top leaves are becoming affected.
I had a similar issue with my last grow with an auto strain, small yield but finished.
Please help me save this girl
Seldom use peatmoss myself, unless I need a little acidity, it's more forging than sulphur. Equal parts peatmoss to compost seems like a lot to be honest.1:1:1 peatmoss, compost and perlite with Dr Forest 444 and 284. I've not had runoff to try prevent overwatering at this stage. No additional fertilisers used so far. I have soft water <30ppm, and I use some Epsom Salt as I've read its hard to over do it?
Sounds like ur tryin to go organic sorry for the misinfo I posted - I still thinkin calmag/watering1:1:1 peatmoss, compost and perlite with Dr Forest 444 and 284.

+1 except I think he can get away with a soil slurry test - 1 part soil 2 parts RO water mix well , let the soil settle 20-30 minutes then ph the waterSeldom use peatmoss myself, unless I need a little acidity, it's more forging than sulphur.

Also although peatmoss does have a tendency to become hydrophobic, it also has a high water holding capacity and sulphur content. Easy substrate to overwater and prone to root rot, because of it's inherent acidity and high water holding capacity.
Usually a good idea to lime peatmoss before use. Also a good idea to lime a soil mix or compost.
Did you add any dolomite lime?
Before planting did you test the pH of the mix?
To be honest if you didn't, I think it's well worth finding out what the current pH is, to rule out acidity.
Use a soil sample to test it.
I'm probably not the one to ask sorry. Indoor soil isn't really my shtick. Coco coir is it's own beast as well, I don't use it as a soil amendment myself.Ahh, would it be a good idea to transplant her into a new mix with coco coir rather than the peatmoss?
Please do.I am doing a soil pH test now and will follow up with the result.
When was it planted?Yes 500ml only twice, the soil seems to retain alot of moisture. Its an 11L fabric pot. No dolomite lime, and added a very small amount of water added at the start to help control dust from the Perlite.
Good stuff.My soil pH is at 5.5. I will try to raise at the next watering in a day or 2
Hey man, glad things are turning around.Thanks guys.
Yesterday I watered 1.5L with a sprinkle of sodium carbonate to raise the pH to 7.1, also some Epsom salt and Molasses. I also topdressed with 444 and aragonite sand.
She's perked right up and had a growth spurt overnight! Hurrah. But now the new leaf edges look light burnt?
This is after I applied some gentle lst.
Sorry may I ask as well, you used enough sodium carbonate to raise the water to 7.1?Thanks guys.

I don’t have an ro system. If I wanted to buy a gallon of water to do this, what should I buy?+1 except I think he can get away with a soil slurry test - 1 part soil 2 parts RO water mix well , let the soil settle 20-30 minutes then ph the water
