Brown spot on leaves
I'm experincing a bad situation. Leaves are becoming brown in the margins and I can't understant exactly the cause. Probably there are more causes, some phosphorus deficiency caused by low temperature but I'm not sure that's the only diagnosis. Someone could help me?

Defoliation late in flower on Auto's
I like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!

Small brown points on older top leaves
1 week ago she started to get small brown points on older top leaves,and I moved her away from light to exclude light burn. Now there are a lot more of them. I flushed her 5 weeks ago, now she is getting full dosage of nutes. But these points look like nutrient deficient to me.

Newbie question about health of seedlings
The tip of 1 of the leaves are slightly burnt, can it be humidity related? I’m having hard time finding a decent humidifier for 2x2x4 tent. I water her with ph water I let sit overnight. Any help or tips are highly appreciated!! 💪

le_epic_doge
I've been getting some of the burnt tips as a result of the watering with nutes. The nute mixture is already half the recommended dose. I've tested my runoff pH and its about 4 or 5 even though I've been pHing my water to be around 7 and no lower than 6. Anyone have any tips?
