Hello,
This is my 2nd grow and I'm 2 weeks in since transplanting 2 different strains (Had a mix up with my seeds so I only know that one of them is either vanilla or critical kush and the other is a complete mystery, 1 is definitely looking like Indica and the other a sativa/hybrid)
Soil: I used a two of the best potting soils available (I live in a country which doesn't have any cannabis tailored products). One of the potting soils contains compost. I put the composted soil at the bottom and the gentler soil on top. Soil pH is 6.8
Set up: Indoors. 250 W HPS. Temp 26-28 C. Humidity 40-50%
In one of the plants (sativa/hybrid) I started noticing brown spots on the fan leaves that would eventually turn yellow and crispy and die. It mainly effected the fan leaves in the light doing the most work. The other indica plant was perfectly healthy.
After doing some research It looked like phosphorus deficiency. However, with the plant at such a young age I was skeptical that it was any kind of deficiency. Further reading suggested that I had over-watered it and that phosphorus deficiency appears with over-watering. This made sense as I may have given the plant too much water when I transferred it to the bigger pot. Although there were no signs of drooping at all, I decided not to water it until the soil dried off. At first it seemed like it was recovering but now it has spread even more. The soil is all dried up and I'm not sure what to do now.
The other indica plant is also starting to show the same signs. I'm beginning to think its a nute burn from the composted soil because the tips are also starting to yellow/brown. Can you get a nute burn from 100% natural organic composted soil?
I've attached some pictures for reference. First three are the sativa/hybrid which is suffering badly, and the other two are the Indica which is starting to get the same brown spots!
Any advice is much appreciated!
Thanks!
