Hello! New to growing and first time on a forum ever. Found a couple seeds and decided now was the time to start learning the grow process. Strains Doug’s Varin, Purple Punch, and possibly Grandaddy Purp. Not auto’s. 4x5 tent, 1200w vispar full spectrum LED.
5 weeks into flowering and after a watering I hurt my plants.
I’ve spent hours looking up possible issues and too many have similar symptoms. I was running high on Nitrogen so I stopped, then I think I got low so I started adding it back in slowly.
Current nutrition Every 3-4 days
4-10-10
Filtered water using a final filter to get Chlorine out ph at 6.4ish
RH usually around 48% (added a temp/RH photo)
Temp 75 day 68-70 night
To me it looks like magnesium deficiency. And a little bit of nutrient burn too.
You could start feeding epsom salt, and that should help. For the most part it looks like you may have started feeding magnesium at some point, because not all of them show it. Am I right?
Just the kool bloom and I gave it to all of them at the same time. Started with 3ml per gallon and then moved to 5ml per gallon recommended usage on the container. Did it every other watering. It has magnesium phosphate, potassium phosphate, and potassium sulfate.
@Covertgrower… so I caught a mistake that might help the issue. I checked my pH of the water and adjusted it BEFORE adding my nutes. Checked the solution this morning before watering with my base/blooming nutes, only needed a third of my pH down. I was running super acidic.
