Day 25 dwc
It’s plant 3, the only one giving issues. The first day is jan 1

Led 2000 watt. Fox farm complete line. ~50% power. Calmag added to ~100 ppm. GH rapid start 50% power. ~65 f at night, 75 during day. Currently in veg 18-6
These brown spots started to appear and have been growing. Several leaves have turned to complete crisp. I have tried adding calmag, lowering ppm, adding addition phosphorus.
White widow feminized
The other two are double the size, and drink twice as much water each day. I grew them identical

I am not sure but could be a phosporus def as well, quite similar symptoms to calcium def.

I would check ph, and if that is ok i would then do a light flush, and add a Phosphorus rich nute to monitor behaviour but i a grow in soil and ph ranges differ from DWC, also flushing techniques i guess.

If you tried cal-mag with no luck, i would try to look deeper into phosphorus def if it was my plant.

Good luck

I refilled about a 1/2 gallons with 300 ppm water with high phosphorus and ca/mag. My hopes are to lower ppm, possible lockout, higher ca/mag and phosphorus. I flip to flower likely Sunday when the rest hit the net. Hopefully she will make it all the way
