The symptoms of your plants indicate a potassium or magnesium deficiency as well as a possible pH problem. Check the pH level of the soil and make sure it is in the optimal range (6.2–7.0). If necessary, specifically supplement with potassium or magnesium (CalMag, Bio Grow, or better yet, Fish Mix). These measures should help alleviate the symptoms.

Pest attack. What can I use to eradicate?3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil?
- The temperatures were very high here, exceeding 30°C, this week it will decrease.
- I have other plants to harvest and I'm going to take advantage and clean the grow.

Last watering I flushed her but the markings seem to be spreading still, although very slowly. What am I dealing with?

Hey, on my biggest plant, the leaves are starting to turn yellow from the outside and getting brown spots. Is that a sign of over-fertilization? All the other plants don't have this. Or is it too little?

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.
