So, the problem is not yet fixed with the rusty spots on the leafs. The Purple Lemonade is the only plant out of my 3 in the tent that has this problem. Both GSC are completely, perfectly healthy. I only watered with CalMag and Silic Rock now, maybe she just needs less nutrients and the symptoms are slight burns. I'll further look into it.
Besides that, the bud sites are really purpling up right now. She is still beautiful even with the yellowing leafs.
Hello buddy 👋i had the same problem one time!
In my opinion the PH at the root is too acidic thats why you have a lock out.
If you have a PH pen you can check the run off water to see if you are in the correct range.
Hope it can help 😊
@valiotoro, I only checked pH here and then when watering, was always around 6.8 which is Fine singe this is an organic grow. The microorganisms should do the rest. I will test the run off next watering tho, thanks for the feedback, buddy!
