Stunted Plant in RDWC bucket?

[_B_]

The plant is a little over two weeks old and looks fine but just isn’t growing.
Room temp is 70-75, water temps are 68-70
45-55% humidity.
Im feeding at a .6 EC or 320ppms and ph stays at 6.0 without any adjustments.
Its under 3 small t5’s (ones burnt out) running 18/6

I like to be about 78 or more, but have grown at 75ish.

Water temp of 68 is good , now warm the room and see if you can keep it up.

300 ppfd for the light

Feed, nothing organic , so that would be a salt based product.

My example , ro water 9 ppm start.
160 ppm of calmag then a-b at there mixing rate to 450ppm , .9ec ph 5.8
In veg, just like your plant now.

Then I use the same formula for flower but would go to .6 , 1.2ec ph 6.

I run no co2.

I also run live , Hygroben.

How far are the lights from the plant? Do you have a light meter of some sort?

No I wish I had a par meter. Im gonna switch out the t5 for my sf4000 and turn it down to about 50% and see if it helps. Don’t wanna stress em out. The t5 was about a foot and a half above em.

I use Masterblend nutrients and SouthernAg for bennies. The only reason I haven’t bumped up the nutes is because they aren’t eating what they have now. Should i try to get the tent warmer with the risk of warmer water temps causing root rot?

If your using the bennies then temp should be no issue as one would use a bit more in a warmer environment.

I pruned the roots back and took most of what was brown out and dropped the water level another half inch. Ill be doing another rez change today and adding a higher dose of Southern Ag (2mL). Ill also be wiping down the buckets just incase there is pythium in em.

Hey _B_ you’re doing things here way beyond my knowledge base, and I am very new to the indoor scene. I’m sure they are not great but i found a couple “light meter” apps for my phone. I have no way of comparing readings so I dont know how accurate it is. If this is false info or bad info I’m sure someone will chime in (please) lol.
