Here is a Northern Lights at 2 weeks of flowering. The plant contiues to grow rapidly and is forming large amounts of crystals already! The only issue I'm having is shown in the photos below. I use General Organic Nutrients. I have not changed the patterns of feeding. I use distilled water ALWAYS. The damage is greater the higher up the plant but like I said, consistent growth! Please help me out!

Maybe it is Calcium. Not caused by cold temp issue in this situation. Room temp water when fed and consistent 70 degrees.

It's mainly P and Mn, but you can also count on Ca, Mg, an Zn being deficient. You need to supplement some fast absorption nute containing this elements like Calmag plus, which also has some N in it. Your PH is most likely too alkaline.

PH stays steady around 7.0. I've ready somewhere and I want someone to kinda fact check me, would flushing it with a flushing agent (can't remember the name I read but help grab the excess stuff) and start back after a good flushing. I don't know if I need to do something that drastic or not. Any suggestions?
