Day 16 Flower...
Two plants left, had to kill the indica because it was a male

PROBLEM!
One of the plants is showing the "claw" from too much nitrogen? The other plant is just fine

I dumped out the reservoir 3 days ago, filled it with nothing but RO water, with a ppm of 50, the next day when i checked the ppm it went up to 150

I was worried about starving them from nutrients, so I added 45ml of cal-mag to 20 gallons bringing the ppm up to 350

Just now I checked the ppm and its up to 420, so I diluted it back down to 350.


What do I do to get rid of this claw?
I have been using just grow nutrients, haven't added the bloom nutrients yet because I read they need a lot of nitrogen in the first two weeks flower

Should I start using the bloom nutrients instead hoping it will get rid of the claw? Or should I flush them again?

I NEED EXPERT ADVICE! :greenthumb:

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?
