Day 43 5/22: I watered and fed yesterday right before lights out since I fear she was dried out too much. Came back to her this morning and should see a slight burn on the tips on leaves. I did bump up the feeding to try and help with the nitrogen deficiency. Trimmed off the yellow lower leaves and now hoping for the best!
Day 46: it had been really hot the past couple days where the tent gets to 88f and I started to notice the tips of leaves curling downward. They are drinking much faster now too so I just watered them till they were heavy again with a bit of calmag added.
Day 48: watered and fed today. Temps are down to high 70s now which is better. Still a few leaves curled but overall she looks healthy. She's definitely starting to fatten up.
My leaf tips are starting to culr downwards during week 4 of flower for my auto. My Temps have been up to 83 right now with the weather and with around 47% humidity. Any ideas?
Too much nitrogen. Super early sign of nitrogen toxicity. Cut back on nitrogen but maintain upped levels of potassium and phosphorus. Leaves won't repair.
