Rdwc nutrient issue need help identifying

MrUnchained · Jan 27, 2022

44 gal expanded clay pellets 5.8PH tent temp 72f
12 plants. Im feeding with tps one. I have one plant that is much worse than the others but it is the largest one. So im guessing im lacking in something but I dont want to guess as I am new to rdwc.

The rust spots are most likely due to a calmag deficiency. This make sense since it has the most growth meaning that it has used up a lot of nutrients. I know you're using a one part mix but I would really recommend getting a cal-mag supplement. I'm not familiar with RDWC but I do know that those rust spots are from not enough calmag

Check for...
1 root rot
2 ph is correct including calibrating your ph meter
Then
3 change your res and put in fresh nutes at ec 1.5

Also is it warm enough?

Light stress or pH.
