So I’m not sure what’s wrong with my girls, I’ll hopefully put more info than needed.
4 do si do in my rdwc, they sprouted about 3 weeks ago on March 7th. Were getting seedling strength nutes from the start according to the GWE chart, 1ml/gal cal mag added about a week after sprout.
Some things that have happened, In the beginning weeks my water temp was consistently going over 76 so I installed a water chiller on the 21st, my roots looked slightly brown at the time, I was running hydroguard so I believed the browning was nute stain.
About 4 or 5 days ago I started seeing some yellowing tips on the smaller plant pictured, assumed some nutrient burn and changed my water out, wiped everything down, filled with plain ph water for 24 hours, then gh micro trio at 1/2 tsp a gallon. No hydroguard or calmag. Ph was stable at 5.8/.9 330w (actual) led at about 7/11 power (dimmer goes to 11) hanging 22†from top of tallest plant.
Day before yesterday I checked my roots and the “nute stain†was significantly worse, roots were slimy and tangled up. (Pics included) Although no smell I assumed root rot even though my water temps have been 66-68 since the 21st. I cleaned my roots with my sink faucet since it has a sprayer, cleaned them white and put hydroguard in my water, along with 1ml/gal calmag..not 100% why I added calmag then but I did.
They’ve been getting progressively droopier as time goes by and I’m noticing the brown spots on the smaller plant, brown/reddish spots on the newest growth of the same plant, and a little clawing down on the bigger plants, roots still look good (whiter pics of roots now)
Air temps have been 70-80, humidity 40-60, using tap water that comes out 180 ppm, with nutes ppm goes to 600, with calmag it sits at 700. Brought ph up to 6.3 today to see if maybe different nutes need to be absorbed.
As I write this I’m noticing the 2 times I’ve seen problems above water has been after adding calmag. Other things that I think I messed up with is using the sink faucet directly on the roots instead of cleaning them with a toothbrush or something in ph water, and not using h202 after believing I had root rot.
I’m just as green as these plants when it comes to growing so I really appreciate everybody’s continued support with these shenanigans. Sorry for the novel.
