What seems to be the Officer, problem?

DWC
TENT Temps 75
Humidity 50-60
Water temps 65-69
PPM 715-650
pH 6.0-5.7
Lights Viparspectre KS5000 (16inches from canopy @100%

I feed 3tsp of Cal/ Mag 4 gallons of water (ppm of tap water is 100 fyi)

3rd week of flower

I’ve never had any problems with DWC growing.
It starts from the bottom and grows towards the top. Starts from the tips and spreads. It stopped in the last week of veg and just started again 2 weeks ago. I have no idea what’s going on. I’m afraid I might lose her

this looks like cal/mag to me add another tsp

Looking a bit like the beginning of a phosphorus deficiency, Excess Ca is antagonistic to phosphorus and can restrict its absorption. It’s possible that your base water has quite a bit of Ca, and with the added calmag it’s restricting the uptake of phosphorus. Another thought is that at your current PPM level of less than 550 (once you subtract the base water PPM), your plants are hungry.

The cal/mag I add is 4-0-0 extra cal mag

Should I cut the cal/mag to 2tsp per 4gallon and push ppm to 900? I was thinking about flushing her with distilled water for 24 hrs and replacing with 900ppm -100ppm tap water = 800ppm

You could do that, basically do a re-set and then boost the ppm’s, or you could just do the boost. Your call.

Wish me luck! I’d hate to get rid of the plant. I started it June and took clones off of its mother. The mother was vigorous. The roots exploded in 4 days of putting her into the DWC bucket. Because it was too hot during summer had to trash her. So I took a clone and placed her in soil. And cloned about 3 more times after that just so I can grow her in October. 5 months of work plus up until now extra 2 more month making 7 months trashed. I really hope this works bro!!
