Hello this is my 2 grow auto Train wreck in dwc or as I call them bubble buckets in a 3'X3'X6 tent with 315 watt CMH started started with 4 seeds only 2 germinated about 2 weeks ago they seem small to me just added Hydroguard and one teaspoon of GH Floranova one part nutrient grow. Inside the tent the temp is 75 degrees F. Humidity is 37% water temp is 70.5 F and PH is 5.7 TDS is 465 in one and 475 in the other. My CMH light is set 20 hours on and 4 off during the hottest time of the day. Question: How do they look? I started germination on April 8th so 2 weeks today. 4 days ago I removed them from the humidity dome and changed from T-5 growlight to the CMH it's 36" from the seedlings scared to get the light to close burned up some seedlings on my first grow because of that.
Thank you

They look about right for 2 weeks. Your TDS might be a bit high and the humidity is way low. Shoot for at least 65-70% in veg, then 50-55% in flower, lowering to 45% the last couple weeks. Watch your node spacing. Raise or lower you lights to keep it at round 1/2"

Yesterday was 3 weeks for my babies I made a few changes covered one bucket with reflecting tape and put the other into a Igloo cooler started with a Rdwc system just keep having problems with leaks and keeping it stealthy as I can with a 6" tent! The Igloo is doing great keeping the water temp down around 65 to 68 F, the square bucket is not as good 70 to 71 F keep adding ice packs to bring the temp down using Hydroguard in both just adding 3 ml's

to both last H2o change 7 days ago. Roots are doing great the problem with living in Hell is finding clean H20 TDS is 194 before I add anything Ph is 6.5 I guess Hell has better water than I thought. My question is I'm using GH Floranova one part nutrients do I feed every day? My TDS is going to go up real fast and I'm a little wary of Hydroguard the first time I used it i kept adding 2 ml's everytime i added water ended up with foam and dead roots. TDS is running in the 500's today I'm going to to do a H2o change today

No, there is no need to feed daily. Ideally your pH should rise slightly and the ppm should drop daily if your plants are feeding good. If it's going the other direction, pH going down and ppm rising, you are overfeeding.
