Hello, I’m in week 3 flower with 2 autoflower Gorilla Zkittlez in a 2x4 tent in individual hydrobuckets. My EC increased dramatically when I started flower nutes a couple weeks ago, seeing a little sign of burn, semi-expexted that. For the last 2-3 days my right girl has EC continuing to rise to 2.2 and I’ve realized I may have a nutrient lock out or something related to higher EC. Ph is steady 5.8 to 6.2. The plant is starting look lighter green than the other as well. I’m planning a full water change to reset, my question is: is it advisable to run strictly water and a flushing product for a day or two before I reintroduce a new fresh batch of nutes?
My thinking here is it will give the plants a rest from the strong nutes and dissolve any solids that may be building up.
If you’re going to run straight water I would do so for something like a few hours more so than a few days. If setting your ph at 5.8 adjust it back down when it hits 6.0 rather than allowing to get higher.
There is a relationship between what plants are taking and what is left in your res. The nutrients in your solution buffer the ph and content of your solution will drift with amout of water plants take. Keepimg all of this balanced us the key to having a healthy hydroponic system.
I agree if still planning on feeding then I would only use straight water for six hours then back to feeding. Also are you running hydrogaurd or ec roots in your buckets?
I agree @Myfriendis410, 2.2 is not horrible, but its up to 2.3 this AM. I’m more trying to understand why the plants were identical until several days ago and how to deal with the rising EC in one versus “normal” behavior in the other.
I am a fairly new grower and trying to diagnose the current plants as well as learn and understand the big picture for hydro.
I could detect the difference in the water via monitoring ph, EC, and visual water level several days ago, and now I am beginning to see a difference in the plants themselves.
Thanks for your time
