look like bigger plant is suffering from magnesium deficiency, and smaller plant is probably rootbound and suffering from nitrogen deficiency. https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

Spotted crisp leaves
What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Yellowed tips
good evening guys the tips of the leaves (40%) show signs of yellowing and dryness (only the tips). i read that it could be overfert or too much water. I've also read about lifting from the pot (done), checking the roots (healthy), letting the plant breathe out, cleaning the walls of the pot, and replanting. it should be enough? do you think they are the right moves to make?

Burnt and drying leaves
Any idea what I might have done wrong on the sick mothman maybe nutrient lock or overwatered? It was the only plant without drainage hole and stayed pretty soaked as I was out of town for 3 days. Any advice is appreciated!

Leaves burn
Hi! Is this nutes burn? Damage is on the upper/middle part of the canopy on very few leaves, but many more have black tips. I’m puzzled because during veg I was feeding the plant higher ppm than now and never had a problem!

What could this be?
What could this be? It's NL auto with a hydro set up in the transition phase. I believe it had nitrogen lock prior due to over feeding nutrients. I cut all the old leaves that had this and it keeps happening to leaves that we're healthy. Was much darker green and looks better now
