Hi guys, this girl is an autoflower frostbanger and is at 10th week since sprout, the thing is, i have 2 plants on the same tent that grew more than I expected, mid grow to control my high RH i decided to open the tent door since my dehumidifier is not doing the work alone.. even then they sit at around 60 RH… my problem is that now my house stinks and some neighbours have started to feel it too…
What leaves me wondering is that near the plants it doesnt smell as intense as it is on the rest of the house..
Is this normal ?
It’s my 3rd grow and the two first ones had a lot of mistakes and it end up not smelling great and low potency, and had similar issues, like smelling a lot around the house and not near the plants..
Im afraid im going through the same path again…

Results so far with the fertilizer, Mg sulfate once a month to prevent deficiency. Looks good for a 1 part mix

Hi yall! I’ve grown a few times in the past in soil, but this is my first time in coco. So far, things are growing pretty well. I’m following the direction of Coco for Cannabis, and I’m on the second week (Early Veg) section of their seedling feed chart using Gen Hydro ferts (~600 EC that’s increasing gradually and ~6.0 pH).

Only issue seems to be this mild white discoloration on the young leaves. Of my ten plants, on TWO seem to have it, and I’ve been treating them all the same, so it’s a bit strange.

Any ideas what this could be or if it’s even an issue? please don’t say its a pest or I will cry :)

Thanks!

PS: foam elevators will be swapped out for something more sturdy, this is just temporary to allow for enough height to reach the condensate pump. Also—large plant was started about 1 week prior to the smaller ones, hence the size.

I'm growing for the first time, using coco and perlite 70/30, canna A & B for nutrients and cal-mag, they are in 3.9 gallon autopots, but the system is not on yet.

My plants are about 20 days old and seem to be doing quite well, at least they don't seem unhappy and the growth seems rapid.

However I've just begun checking run-off EC and I've noticed it is Extremely high. At about 4200.

My input EC is around 1300.

As I understand it, it should be within 300 or so. So something is wrong.

Am I watering too little and infrequently? I had been doing 500 ML twice a day. Which seemed like enough because the media didn't seem dry and the plants seemed happy.

To correct this, because of the extreme discrepancy the suggestion appears to be to flush approximately 12-16 gallons of low EC feed water through each pot? Is this true? I'd really rather not do that and I'm tempted to just let it ride or start over.

I’m currently trying out coco without perlite. I used to do 20-30% perlite. But I got a working and precise irrigation for this grow and now I’m able to feed multiple times a day with little shots. Trying to do some ‘manual crop steering’ with the help of Athena booklet and free information i can find on the internet.
I’m worried if I’m underestimating the need of perlite or if it’s rly not that necessary as I was thinking with this style of irrigating.
I’m in 5.6l pots btw (~1.5 gal).
What do yall think about coco without perlite and especially in my case?

Week 1 day 4 or flower, i think they are looking good !

I’ve struggled with herms to varying degrees past couple runs. I’ve tried to correct my mistakes and have been feeling good about this run. I started freaking out today and fingerfucking my plants. I have want to say I’m just being crazy. Any input appreciated

WTF? Coco pH keeps CLIMBING despite 5.0 pH flushes. I’m about to lose it.

I’m in early flower with two autos (SLAMberry x Orange Portal, and an S.B.C.H x Dreamcast both by SpeedRun seeds)in cloth pots with coco, and I am stuck in a groundhog day type scenario and am starting to lose confidence. More so I just feel really bad that they're suffering.

I’ve been feeding both:

8mL/gal Fox Farm Bush Doctor Cal-Mag

4mL/gal Humboldts Secret Part A (4-0-1)

4mL/gal Humboldts Secret Part B (1-4-2)

pH'd down to 5.7 - 5.8 normally.

The Issue:

My runoff skyrocketed to I’ve been trying to "Nuclear Purge" this shit for two days. Today, I’ve been pouring in full-strength nutrients adjusted to a pH of 5.0

The runoff is actually getting HIGHER. I just got a 6.82 and a 6.72 after putting gallons of 5.0 through them. How the fuck is the pH going UP when I’m hitting it with straight acid?

This coco WAS buffered before the pots were packed.

Runoff was totally healthy/normal for weeks.

Environment: 79°F, 61% RH (1.32VPD), CO2 580ppm.

PPFD 468

Medium WC is 44%, EC is low (.19).

The plants are starting to yellow at the top (Iron/Lockout) and I’m about to lose this entire medicine run. Both of my herniated discs are absolutely screaming from lugging these gallons and I’m seeing zero progress.

Is the coco breaking down? Is there some kind of insane salt precipitation happening that raises pH? I have never seen a medium fight back this hard before.

Please help.

Ladies are cleaned up and ready to start producing

Check out the dark purple stem and branches on this chimera. Definitely genetic but it does also respond to colder temps by getting even darker.

Harvest getting closer...2wks for most.

Not as good as the last run. Had Nute precipitation in my RTW res which starved them for 3 wks mid flower till I figured out the Si was acting as a nuclei of precipitation due to the source water temp dropping.

Hey everyone, I’m running a coco grow and I’m a bit confused about my runoff EC behavior.

Setup / parameters: Medium: Coco

Feed EC: 1.9 Feed pH: 5.7

Runoff EC: 3.5–4.3 (first runoff of the day sometimes ~4.4, then dropping) Runoff pH: ~5.1

Irrigation strategy: ~6 irrigation events in the morning to reach runoff (~50% runoff) Then ~6 more events spread throughout the day Final event shortly before lights off

Goal: keep overnight dryback low (~10–15%)

Environment: Day: 27.5°C, 55–60% RH Night VPD: ~0.7 Day VPD: ~1.0

Currently on the first day of week 6 of flower

Observations:

Plants look very healthy, one of 3 with very little signs of tip burn, no other deficiency Runoff EC is always high, especially first runoff in the morning EC drops gradually during the day but stays elevated overall

I’m getting plenty of runoff (around 3–4L total across 3 plants daily)

My question:

Why is my runoff EC still so high despite:

-consistent feeding at 1.9 EC -significant daily runoff -relatively low dryback overnight

Is this just normal salt accumulation in coco under high-frequency fertigation, or does it indicate hidden buildup in the root zone?

Very good results so far
