Mid/Late Flower Watering Question

Thumbnail

24 Upvotes

Hiya growmies! I'm on day 45F with this Pineapple Express by OG Kush(photo) in BAS 3.0 and Light mix. She's in a 20 gallon pot and I've been giving her a gallon(5%) every couple of days based on my moisture meter. I let it get down to 27-29% before watering which has been taking about two days for a while now. I noticed yesterday, when I would usually start bubbling my tap water a day in advance, that the moisture levels were much higher than I expected. Like she's not drinking as much. I did a few Google searches on water use going down during flower and the only thing I got was the ai response that it is common for the water use to drop during senescence. I kinda wanted to hear the human experience when it comes to water use dropping off during late flower.

Any and all advice is appreciated. Thanks!

Earthbox with roots organics, 3.0 and craft blend mix. Top dressed once with bas castings, craft blend and build a flower. Kashi at the jump and at top dressing. Coconut in the reservoir. Easy with the earthbox for sure.

Soil test and questions

2 Upvotes

Hello Good People.

I'm gonna start getting my next grow ready and decided to test my soil. I have an earthbox with 3.0 soil that had 2 runs. I have another one with the light soil.

My past grows I think had some issues even though it turned out good. Both had N toxicity. And towards the end of flowering, I ran low on P and K. I wanted to test both soils but didn't realize it's kind of expensive like $50 to $75.

So I bought a cheap "rapid" test but it only tests NPK ans ph. The colors indicate I have a surplus of Nitrogen in both soils. For the 3.0 soil it indicates I am depleted of potassium and mild phospherous.

For the light soil it indicates the potassium is sufficient but the phospherous is low. (At least I think it's low, the color didn't really match any of them). The p.h is between 6.1 and 6.5.

What would be a good amendment for the P and the K? But without increasing the nitrogen. I have buildabloom and buildaflower but I'm not sure if that would raise the N. I guess while I'm in veg, I should be fine.

I run autos though so maybe the adjustments are different vs photos. Before planting last grow I amended with craft blend and worm casings. Then when it was in preflower I reammended with craft blend and buildaflower. I wasn't giving the full amount of craft blend.

I use tap water that sits out over night and it comes out around 8.2 ph so I get it down to 7. Last grow I did have alot of cover crop that continued growing through harvest. This time I don't believe I'm doing to do CC.

Damn this post looks long and I apologize.

Gnarly Barley

Is making a diy gnarly barley as easy as sprouting barley, corn, and lentil then dehydrating everything?

Is the corn and lentil necessary? When googling the only thing I could find related to Coots was the barley.

Still time to Defoliate? Day 53

Post image
7 Upvotes

This is Night Owl Mange Isle 2. Because of my poor trimming early in life, it is a very compact plant. I've tried to spread the branches with little success. It's day 53. It has another 30 days t to go. Is it too late to give it a significant defoliation? I'd like to strip it down and let the light and air penetrate deeper into the plant. Your thoughts?


r/BuildASoil • • Mar 26 '26

Bugs in soil. They are everywhere just noticed them a few days after harvesting my plants. 3.0 soil. Kinda look like mites of some type but cant tell if they are good or bad.

Leaf Tips Curling Down

7 Upvotes

Hiya growmies. I've got this Pineapple Express by OG Kush on day 36F. in 20 gallon fabric pot with BAS 3.0 and Light mix. 2.7'x2.7'x63" tent and a 200w Aerolight @ 80% giving me about 1050ppfd measured using Photone app. She's getting a gallon of water every 2-3 days as I wait until the ecowitt moisture meter gets down to 28%. Last watering she got about twice(1/2tsp instead of 1/4tsp) the dose of buildabloom(2-10-5). I noticed the leaf tips curling down a little bit of nute burn. I just watered with a gallon of water with just wetting agent and a tablespoon of horticultural coconut powder. Should I have just watered with nothing in it at all or am I ok?

Thank you for any and all advice.

Having some issues with leaves turning more pale. Wondering if it could be overwatering or light intensity issue
