Good to see some kerala action!
That looks like it was a K problem to my eyes, all day long. I do see some slight P issues (the reddened petioles), but the boy looks like he was suffering a K problem. Uptake, utilization, deficiency? I don't know. How long have you been using the soil mix that you posted above? It may need a wee bit of tweaking if it's a new recipe. Otherwise, though, they look fantastic to me.Issues with Kerala x Skunk 1
As has been stated in my first post, temperature and temp swings have been something I've dealt with this grow (started all my plants too early this year). So I noticed some leaf tip upward curling and margin curling along with some dry crispiness and lime-green coloration of some leaves on the tallest tops of my KxS1.
Hoping that it was largely due to light intensity--especially since this is my first run with the IG induction lamp--i just raised the IG and and made sure air was circulating around the tops. That was two days ago.
Since then I've had some necrotic spots develop along the edges of some leaves in the middle of the KxS1, and general "crispiness" of affected leaves, with worsening of the dark spots, and more dramatic upward curling.
So my first thought was moisture stress causing some Potassium Phosphorous (and)or Magnesium issues, but it could also be that there is a ton of calcium in the mix locking out Magnesium creating a magnesium deficiency.
But, all that being said, since it is possible for potassium to be modulated by soil temps, and the signs (see pics) really do look more like potassium deficiency, I may be attempting to reverse that as my first route.
Also, the new growth, particularly from the two dominant colas, seems particularly skinny/thin.
My plan was to topdress with EWC, a little kelp meal, and plain dechlorinated water, then give 1/3-1/4 strength foliar of epsom salt water. The only problem with doing all of this is that it treats multiple potential issues meaning i won't know what it was. SO, my new plan is to do the ewc and kelp meal, then wait 3 days or so and see what happens. if its getting worse along the lines of magnesium, then i'll foliar with the epsom.
would love to hear thoughts!
