I also use AN 3 pt with Calmag Plus. Is there a chart for Veg regarding ppms? My plant looks jacked up I am not sure what the ppms should be. Its about 1 month old and it just seems like it stopped growing. I didnt mix in the nutes like abyss stated. I added grow,micro then bloom then calmag plus. Could that be the problem? How I mixed them.

Right now my pms are at 450 (170 tap ppm)
Ph = 5.8 holding steady

Net pots with hydroton mixed with just a little vermiculite but most has fallen out and is washed out during res changes which I do weekly. The water gets a little warm throughout the day from the 400 HID shining down so I pop in a couple of frozen water bottles to get the water temps down a bit. I cant monitor it all day every day as I work.

As far as watering I water 7 times a day @ 20 minutes every 2 to 3 hours. 18/6 lights on/off no water in darkness.

Ambient temps may be contributing to the problem. When the lights go off I would say the temps in the grow space drop 5 to 10 degrees if that. I have a fan on 24/7 for air circulation

The tap root is hanging down into the water which is has 2 aerrators and a submersable pump on 24/7 for increased oxygen in the water.

Humidity ranges 50-60%

No sure what I left out but from the info I have provided and the photos what do you all think?

Not enough nutes for plants age?
Temperature both water and/or ambient as contibuting factors?

improper nute mixing?

Is it okay for the tap root to be constantly in the water?

Some of the clay pebbles have a white residue on them.

This is a top drip feed set up.

PLEASE ADVICE OPINIONS GUIDENCE

anything!

Thanks
