I’m not sure there is any way to get the creases out unfortunately.

@jd187 Thanks for continuing to share your garden! I’m glad you like the Chill Out OG

[mrgrowit]

I appreciate your positive words! Those are some nice looking plants you got there. Cheers!

From the pics, everything looks good so far! Nice job.

I’ll add him to the list of potential guests. Just to give you a heads up, there is over 200 names on the list.

Just to clarify, you are talking about tissue testing right?

Not sure if you watched the episode or not but I did get an answer for you.

Dolomite lime can help adjust the pH, but dialing in the right amount can be tricky. I’ve heard too many horror stories where dolomite lime was added and the pH swung too far and they couldn’t get it back in range, so I personally avoid using it. But with a runoff pH of 6 and 6.3 like you mention, it doesn’t sound like there’s a really need for it imo.

You could top, super crop, and/or LST to help control height. I’d wait to flip until I see new growth that appears healthy.

Oh yeah I know who you’re talking about. I heard he actually got arrested for selling on the black market and is currently locked up. I honestly didn’t get a good vibe from him and got feedback privately to watch out for him. So I’m not sure how much of his info is actually trustworthy. That aside, microbes are a key component for organic matter breakdown. Even if I didn’t “have a lot of microbial life in pots that small”, the microbes there were still actively breaking down the organic matter and nutrient cycling was happening – or else the plant wouldn’t grow or be healthy. So to answer your last question, yes I think microbes are really much of a factor when growing with organic inputs.

[mrgrowit]

Good question! If we are talking about overall plant growth, I don’t think we can only look at VPD here. I think we need to loop in microbe activity at the different temps into this conversation; the lower the temp, the slower the microbes operate. Sure, the .8-.9 VPD may be more ideal for the stomata opening but you slow down microbes activity breaking down organic matter when running the lower temp.

The higher the temp the faster metabolic processes in the plant can happen – assuming all other variables are the same. I’d aim for the “1.1-1.2 VPD at 74-75 degree leaf temps” you mention vs “.8-.9 VPD at 69-70 degree” since the temp is higher and the VPD is still within the tolerance range – even though .8-.9 is in the optimal range.

I personally like to run 80-82°F lights on up until 2-weeks prior to harvest where I will then drop the temp to 78°F to try to conserve terpenes. Looking the the VPD charts, the optimal RH for 80-82°F temp in Veg would be about 64-68% RH (0.9-1.1 kPa), and  about 51-60% RH (1.3-1.5 kPa) in flower. That’s factoring in a -2°F leaf surface temperature adjustment.

This post was stuck in pending; sorry about that. I don’t know why that happens.

Thanks for post the details on your grow; it makes it a bit easier to help diagnose. Looks identical to magnesium deficiency. Here’s more info on it:

Do you have CalMag on hand?

Edit: Also could be pH fluctuations causing it. More info:

This post was stuck in pending; sorry about that. I don’t know why that happens. I believe you created this post back in December. Do you still need help with this?

[mrgrowit]

Interesting. Got a pic of the entire tent and another pic of just that one plant? It sounds like you’re doing everything right and so maybe this plant is a heavier feeder, or the plant could have a virus or viroid. Maybe the pictures will help us identify something.

Q1. I’d LST and last resort prune off the branch if it’s in jeopardy of being too close to the light. I’ve had a plant throw nanners before since the plant had one main branch that I couldn’t LST and it was only 8″ from the light. It sucked big time so now I won’t hesitate to prune off a branch or two if it means the rest of the plant will be better.

Q2. I typically look to prune one last time at day 21 of flower. Although sometimes within flowering, buds will form down there still so I find myself randomly plucking them off in flower.

Can we get some more info? Are you in soil or coco? If soil, what brand? Did you amend in any fertilizer before planting? What size container?

One of the biggest contributing factors to the plant showing deficiencies is the soil being too wet or too dry. Do you have a moisture meter? If not, can you tell us how you go about watering and determining if the soil is moist enough or not?

[mrgrowit]

I’m assuming you have the mixture in a reservoir; is that correct? Are you using a mixer or air stones? Also, what nutrient lineup are you using?
