From what I can see in the pics, it looks like your Amnesia Haze is showing signs of a deficiency, but since you’re already adding CalMag and keeping the pH in range, it might be something else.
I’ve got a theory: could you be dealing with a nutrient lockout from too much phosphorus? You’re using PhosphorBoost, which is great for flowering, but if you’re adding too much, phosphorus can sometimes block the absorption of other nutrients like calcium or magnesium. That might explain why the CalMag you added hasn’t helped much.
I’d suggest doing a flush with pH-balanced water (around 6.2-6.5) to clear out any nutrient buildup that might be causing the lockout. After the flush, maybe cut back a bit on the PhosphorBoost and stick to a more balanced feeding schedule but at moderate doses.
Remember, these things can take a little time to fix, so keep an eye on the plant for the next few days after making these adjustments.
Good luck with that Amnesia! Keep humidity and ventilation in check, especially now during the flowering stage. If things don’t get better, pop back on here and we’ll figure it out together!
Yeah I already thought about too much Phosphor, but my other 2 plants (different strain) are looking absolutely great with the same amount of Phosphor.
I flushed Amy yesterday with 2.5 Liters!
I‘ll keep you updated guys!
