Everything I did find said moisture stress, cold temperatures or pH balance is off. I tried looking everywhere and didn't get much information. The only other thing I seen was potassium deficiency but I SERIOUSLY doubt that. I still think it was caused by the rains giving them moisture stress, making them cold like Robert's said, or your pH fell out of place because the rains. I'm sorry I couldn't find more. I really tried man.

Thanks a lot man, I'm gonna check my pH tonight and build up slow again with nutrients. From now on she will not spend a day in the rain anymore haha 😂 I allow it untill second or 3rd week of flowering outside, after that it's just an open invitation for budrot. Thanks again man. Happy growing 🙏😉

I will, she had some ph fluctuations but last time checking she had 6,2 so that was perfect. I dropped down on the nutrients too since I had some signs of overfeeding

I still think it was from the rains. Can you check the pH in your medium?

Popped up around last week (week 4, monday). Prior to week 4, i had been watering with tap water, which in my area is pretty hard.(7.8+ pH) Been correcting pH to 6.8 with each watering since. (2 waterings since then.) Should i just continue feeding 6.8 pH water or add cal-mag?

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

These three girls are all wilting and/or barely growing. I'd say over-watering except I've only been giving maybe a quart then waiting till the soil dries a little bit. Not too much tho. Could it be a nutrient problem already?

Seeing some top bud leaf discoloration Starting to see small dark/black discolorations on the leaves. Since I don't know the genetics, I can't tell if it's prone to dark leaves. Could it be signs of anything else? Note: Started watering only using TopMax and ActiVera because of some possible Nitrogen toxicity

Yellow leaves with grey/dark outline I have some yellow leaves with grey/dark outline. Do you know the cause? Could be the humidity level too low? or K deficiency?! I'm not so sure about the last one. Help me guys please.

Still cant figure out what's going on with this plant. EC was over 2 for a couple of days but has since been taken care of, last reading was .83.Is this a deficiency or some other kind of issue? Some have suggested a p or k deficiency, but I feed Jack's 20-10-20 peat-lite so I would be very surprised if it was a P problem, and the problem seems to be all over the leaves, but a lot of them start from the base of the leaf.
