Possible N ToxicityI believe I have a N toxicity issue on my hands. Leaves are a dark evergreen color, and I'm noticing some leaves are curling left or right. I've experienced the full out clawing action a while back but never like this. Is anyone able to confirm? How do they look overall?Thank U!6y ago

Hungry? N deficiency?So this sort of just happened overnight. Plants were very thirsty this morning and noticed a handful of leaves that are fading.
I fed them 1tbs of dr earths flower girl and 4ml of calmag in a gallon split between the 2. Should I add some of their 4-4-4 as well?Week 9

Forgot to alter pHHi I forgot to alter the pH. I already have some issues (I think pH? Check picture). What’s worse, overwatering or too high pH? Do I need to flush ASAP or wait till next watering cycle? The pH of the water I used is 7,7 and I have organic potting soil so is it a big deal or not?Feeding. Deficiences

Why isn't it going away?It might be a potassium deficiency and I believe it was so as i was running out of nutrients and i had to lower the nutrient dose i was giving by hand. On the 22nd, i added the nutrients to my AutoPot reservoir so that i no longer had to hand water them and it still has this. SOSWeek 9
