Its getting so close now..

I've been having trouble getting started. She came out looking a bit deform - color was yellowish green and (as can be seen on the picture) she had burned areas. She's way behind my last grow - at day sixteen she's as developed as the last one was at day ten.

Today she had a much healthier color and I could see the roots had finally hit the reservoir - so I think that is the reason. I put another seed to germinate, a couple of days ago, just to be safe. What do you guys think? Should I trash her and hope this next seed does better? I only have one bucket to grow in - the tent is not that big. So I can only grow multiple seedlings until it's time to put it in the bucket.

Edit: forgot the important part - it's an auto, which is why I'm asking. Had it been a photo, I would just let her grow.

Hi all

I am completely new with growing in coco coir. I got dehydrated/compressed coco bricks from European brand. According to the manufacturer, their coco is not only fully rinsed, but also pfe-buffered in factory with calcium nitrate (without magnesium btw). They call it buffered-charged.

The main parameters are:

EC parameter < 0.6 ms/cm (1:1.5)

PH 5.5 - 6.5

I have a AF seeds, which are under germination process now (paper towel method).

1. As I understand it, I need to soak the coco coir with Cal-Mag (typically, not less than 2ml per liter) before planting the seed in it.. Some recommend double buffering (soack two times). Is this justified for a "partially" pre-buffered coco bricks?

I have Advanced Nutrients Cal-Mag Xtra as possible buffering solution. (Total Nitrogen (N) - 4%. Nitric Nitrogen (N) - 4%, Water-soluble calcium oxide (CaO) - 4.5%, Water-soluble megnesium oxide (MgO) - 1.8%).

1. Will any prior or finishing flushing (before seeding) be required? Is an excess of calcium possible? Or should I do a complete flush before any buffering?

2. What are the main precautions? Many recommend not planting seeds directly into a large pots (mine are 20 liters) and translantate plants later. But I can use that same coco coir for growing in a cup, right?

Thanks!

what is happening to our plants 😭 we watch the ph and have the general hydroponics nutrients, fan, and have tried to reduce light leak with foil. we replace the water weekly ish sometime longer, and put nutrients every day or two. we’ve cut some visibly dead leaves but we just don’t know what’s wrong with them….pls help 🙏🙏🙏

So I noticed about 3 days ago my pH was low after weeks of being steady at 5.8 then I noticed my EC went from being 0.60 to 0.55 i adjusted my pH back to 5.8 then it dropped every time. Today 09/28/2026 i noticed on my app my pH went from 5.8 when i adjusted it at midnight to 5.1 by 11 am and my EC dropped to 0.51. Water temp I keep around 68 F - 70 F. Room temp for the tent was 75 I try keeping that lower but I forgot to put the AC on in the room so the humidity was also 70. I did notice the day before that my clay pebbles had why small things on them so I used my loupe and it was white puffs so I removed all the clay pebbles and cleaned them for a bit and let them dry out. I think that part was because they had been too wet from the top feeder. My plant roots are in the water and long. So I technically don’t need the top feeder. Also her leaf has some color changing so one has a brown spot and some have just a lime green patches

I learned using Athena but I’m having really bad issues, recently switched.

Mostly RDWC hydro in 5 gallon buckets, but also a drip system in the big tent with coco perlite in 3 gallon containers. Lots of stuff was done on a budget, so I know now there are better options for a lot of the equipment I have, but everything seems to be doing well.

Let me know what you think!

For those of you who have ran the autoflower line (Bonnie & Clyde) and Cronk in general, how do you do the Bud Booster with the second add during the week? Do you just mix with water and add to your buckets? And how much are you doing? I was planning on running half of what the feed chart says since I'm running RDWC which is what I've been doing with the General Hydroponics line with no issues. Is that what everybody is doing with their nutrients in RDWC?

Thanks for any info...

Summer is coming to an end, so I’m starting to think about the next round.

This summer was mostly cucumbers, which was pretty great when you could just pick one while hanging out by the pool 😅

The system is recirculating NFT with a 100-gallon reservoir. It gets direct sun for around 40% of the day. The reservoir has a float valve topping it up with city water at around 0.7 EC.

I’m using Growee to control pH and EC, and just a simple local Part A + Part B hydroponic nutrient.

Looking for ideas for winter crops that would work well in this setup.

Getting close now..

Large is easier to maintain PH swings and small is easier to clean.

What has work for you?

Pics are some examples I found from google while doing research.

Do you guys cut the whole flower out or just what is damaged

Have an idea for a assisted light outdoor 5 bucket (4 pots 1 reservoir) RDWC grow using an "aquarium chiller" as a heater to heat the circulated reservoir I know that this method at least in tents allows temperatures to exceed its normal heat limits to upwards of +/- 110f and the plants will be perfectly happy.

My question is what do we think is the lowest external temperature that an autoflower would grow in if the heated temperature of the water in all pots stays in the 58-65f zone?

Dit Moi ce que vous en pensé les grower

First time doing hydroponics (DWC), i want to know how much is a regular yield if everythinh goes smooth with a 5 galon bucket

This is my momma plant post clone and flip to 12/12. Strain is Blood Honey by exogenetix. RDWC with Athena nutes. She spent a little too long in veg while I got the grow space setup for the clones so she became a massive plant post stretch.
