Hello Illusion. Nice N Bushy! I would try half grow and half bud nutes at this point. That should take care of any excess N problem. I don't understand how you can be getting burns at PPMs under 500 when you're in flowering. Usually I try to take mine to 1700 or 1800 in the middle of flowering.

Did you know the first 2 sets of photos in your grow won't expand?

First grow Recirculating DWC this grow journal starts off at 37 days into veg. finally got the three babies into the system after a 4 day struggle with leaks they've been flushed with r/o water for 3 days. before they were flushed, i had the ppm of the reservoir up to about 450, cal-mag and GH's MaxiGrow. I noticed slight burning of the tips. Unsure if it's from high ppm, or heat stress. Decided I will reintroduce nutrients *slowly* I should only use cal-mag when i notice signs of deficiency, right?
