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

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!

Is this heat light burn? HPS 600w at 20cm
Is this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).

Hey guys, I don't know what's going on. My ladies seem kind of sad. They were repotted 14 days ago and have now received fertilizer twice. Before that, they had pH adjusted water for 10 days. The fertilizer is Canna Terra, and I'm giving 3 ml per liter of water plus CalMag.
