I was using a salt based fertilizer once a week and just switched away from salt. The 750w light is about 3ft away from the top of the canopy. How would you suggest determining if it is light or nute lockout? I do have some canoeing so you could be spot on that it has something to do with the light.could be lock out of certain nutrients or even light stress?
do you raise the lights as the plant grows?
I bought a clone from a local distillery. I have 2 wedding cake and 2 other that aren't having the same issue.IDK but where did you get the Wedding Cake seeds?
Appreciate the endorsement!Nick knows a whole lot more than I do with LED lighting. He's far more qualified to help you here. I had no idea lighting could possibly be the cause in this case. Hopefully that chart will help you out moving forward. Good luck
Thank you. Soil ph is 6.9-7. I haven't tested the runoff. I will do that. I should water tomorrow. How do you deal with lockout? Is that PH related? Would Epsom salt foliar spray be a good 1st step?This should come in handy https://drcannabis.io/symptoms
That looks to be a magnesium deficiency. It appears you have lockout going on.
What is the medium you're using?
PH?
Nutrient feeding?
PH of runoff if you have checked?
I'm sorry. Just saw the other info. Let me take a look
Just watered and Tested the runoff and it was 6.54ph.Thank you. Soil ph is 6.9-7. I haven't tested the runoff. I will do that. I should water tomorrow. How do you deal with lockout? Is that PH related? Would Epsom salt foliar spray be a good 1st step?
In my setup foiler feeding at 1/4 strength would be the 1st thing I did. I don't know if you would have to dim your lights? I don't know to what strength you would want your lights to foiler feed. That however is only a temporary solution until you get your medium in range. I had this happen to an entire flower room due to a batch of rockwool with too much lime. I soaked for 24, I was feeding at 5.5, and my runoff was coming out near 7. I was way out of range. I spent several hours for 3, or 4 days flushing the rockwool at 5.3. Finally it got back in range, but set me back about a week.Thank you. Soil ph is 6.9-7. I haven't tested the runoff. I will do that. I should water tomorrow. How do you deal with lockout?

Ok, so going in at 5.9, and coming out at 6.5-6.6 ish?Just watered and Tested the runoff and it was 6.54ph.
Yes. Correct.Ok, so going in at 5.9, and coming out at 6.5-6.6 ish?
I am using a ph corrector. I am wanting to switch to apple cider vinegar. My tap water comes out between 11 and 8. I didn't add any amendments. I will be doing this differently next grow. This is my 1st grow in 20 years and I am relearning and learning a lot. I have had all the things happening this grow.You're using lemon juice for your ph down? Did you ammend the soil with lime, oyster shells, or anything else that would be alkalinic?
So I assume you are using well water? That would explain a lot if soI am using a ph corrector. I am wanting to switch to apple cider vinegar. My tap water comes out between 11 and 8.
