Nice. Yeah I'm still trying different things to solve various problems. Tried hanging my heater to get away from buckets so the bucket water temp stays down. Well that works until lights off, where the exhaust is just sucking out the heat and the heater does nothing. Came into my room at 59 degrees and 18% humidity, however my buckets were a comfy 65 degrees. Tried putting heater back on floor, heats up buckets again but lights off temp got back to 64. Now I'm leaving on floor and elevating heater so it doesn't directly hit buckets. My humidity was getting wayyy too high lights off so now I leave my exhaust fan on full time. Lights on I have a humidifier that runs gets humidity to 30-35 and 70 degrees. Plants are happy and starting to flower. 2 are nice and frosty too

Also I decided to go negative pressure in the room to avoid any fungus or rot issues. All flaps closed and exhaust only running 24/7. no intake fan. I have a cfm kit from gorilla so my tent can handle it

Yeah ph too low is what your thinking ?
I didn't notice anything about your pH. I'm a big fan of always checking pH because too high or too low, and you got nutrient deficiencies. I stay around 5.8 and always have good results with no deficiencies. I had a calcium/magnesium deficiency, but since then, all my plants have had no problems. By the way, I'm also building my own water chiller. Much cheaper, and much smaller. Water temps should be no more than 70 degrees Fahrenheit from what I have studied. P.S. sorry for the late reply, been real busy. Hope your grow is going good.

I check it every day and try to keep it at 5.7-6.0. just adjust ph daily until I get to .5 or .6 change in 24 hrs that's when I change water. Changing tonight actually after 8 days
Usually my pH wants to sit 6.2ish after water change for 48hrs with my AN sensi bloom, but I try to keep it at 6.0

Plants look great but I have a big problem I'm solving with mosquito bits. I noticed some gnats in my buckets but have been ignoring, well they are becoming more prolific so I added some bits to my buckets. 24hrs later I've got dozens of apparently dead drain fly larvae stuck in my roots none of these were present 24 hrs ago not one. So I'm hoping the bits did their job and killed them all and that's why I'm seeing them now.PHOTO_20210219_185438.jpgPHOTO_20210219_184734.jpg

Wow I forgot about this. This grow turned out good I harvested 4 plants. Had problems with pH crashing at the end and have since started a new grow. This time I made my own RDWC system out of three 27 gallon bins, added a danner 500gph pump and a chiller. Just hit first week of flower, plants looking great. Not changing the water either! I add about 2-4 gallons daily as of now in a 30 gallon system. Chiller at 67 degrees, running lotus nutrients this time, flying skull z7 enzyme, hydroguard and cal mag (RO water). That's it plants super strong and healthy.
