100%@tobh now thats vpd issue no?
its inside rockwool.improper watering techniques
not necessarily in rockwool. they look overwatered, and in a sense they are. the problem is they aren't transpiring because the environment isn't conducive to the plants doing what they know they should be doing given the other proper parameters.improper watering techniques
oh sorry..its inside rockwool.
no need to apologize :) @PK1 is suffering the same thing atm and found a good partner example of his symptoms. quick learner, he is, with a great eye.oh sorry..
well you guys got this one..
thanks for noticing!
Im at 1.6 ec feeding twice a day 150ml i may wait a couple days since my dry back was too much from my vpd issue I may have had a salt build up run off was 3.0 - 3.2. I will be testing today at last feed. every 5 days? What volume are you feeding them? maybe I'm confused about dryness of the blocks or just let the blocks dry out too much from the get but I don't think my plants will survive 5 days. If your right it would explain the issues I'm having. no better way than trying it out on one of them. I am Waiting on a flood and drain bucket system to show up its apparenlty "stuck at the port". so, my top watering knowledge may be for nothing because flooding from bottom is going to change things dramatically.here is a chart i try to follow to get the temps and humidity right.
How much are you feeding that the runoff is 2,2ec? That's quiet high number for this stage if its correct. Try grabbing a syringe and remove some water from the cube and test the water that you are taking out of the rockwool. The cubes need proper drybacks and feeding.
I notice that my smaller plants in 4" cube need watering every five days while my bigger plant in 4" cube needs water everyday.
took your idea of syringe and got some water to my surprise meter skyrocketed to orr past 5.0!!!!!! quick meter cal test its good. Im lost!! i upped my volume of 100ml to 150ml to flush the cube out better it somehow it made things worse. i guess worst part is i just did the last watering of the day. if i flush with ph'd ro water will i just overwater it at this point or its it my only option? in past experiences things havent moved so slow. the stems on these are 3/8" wide too and only 10 in tall seems to be just me causing the issues the plants are hanging in there doing thier best. @tobh @PK1I don't know how much roots there are in the cubes and my seven days was an example on my seedlings. I also mention my bigger plants need water everyday.
I find a good practice is to pick the rockwool up after it is watered to see how heavy it is and than let it dry back and fine tune this timing so that the rockwool is never too wet and or too dry.
I'm actually working on this right now myself
apperently you can't overwater rockwool. also, 150ml is not much i would assume for that stage of your plant if it has allot of roots.took your idea of syringe and got some water to my surprise meter skyrocketed to orr past 5.0!!!!!! quick meter cal test its good. Im lost!! i upped my volume of 100ml to 150ml to flush the cube out better it somehow it made things worse. i guess worst part is i just did the last watering of the day. if i flush with ph'd ro water will i just overwater it at this point or its it my only option? in past experiences things havent moved so slow. the stems on these are 3/8" wide too and only 10 in tall seems to be just me causing the issues the plants are hanging in there doing thier best. @tobh @PK1
is this calibrated properly?
it measures 2.7 in the 2.7 solution. maybe my understanding of rockwool isnt correct or im overthinking it myself . by the last watering i should have 10% runoff correct?? i dont know where i heard that but it sounded right to me and i figured it would be a start. that's what i based my volumes on really once i moved them into the 4" cubes. my understanding of it may be leading to excess dry backs causing tension in media and high ec runoff. when i upped the volumes it wasnt enough and pushed everything to bottom of cube is my guess. man what a ride!!! but its enjoyable to say the least . im going to figure out if you can overwater rockwool today and ill let you know lol!!is this calibrated properly?
