First time grower
Hi Everyone, I’ve been coming here for years to learn. I finally grew a plant past flowering and I chose a Nirvanna Northern lights autoflower for my first time. No training and trimmed fan leaves until 3rd week. Using a 2.3 x 2.3ft Mars hydro tent. With a TSW1000 LED full spectrum,16 inches above top, had it on 18-6 cycle entire time. 5 gallon cloth pots, using bluesky organics super soil. No nutes used and from the tap water. Tent temp and humidity have relatively been on par 23 degrees Celsius, 40-50% humidity. At about 7 weeks I had some issues with leaves yellowing, with browning spots, and falling off eventually, I am now at 10 weeks and not much growth has happened since. From research this is an overwatering issue which that’s what I attribute it to as I haven’t been as observant and interactive with her as I should have.
The question is does this issue really come from a watering issue or possibly nutrition. And are the instruments that tell me things like soil moisture and ph balances worth investing in to gain a better understanding of what my soil and plant need?

I am not a soil grower but it looks hungry and thirsty to me

so the tools that you are talking about would definitely give you a better advantage. A PPM meter will tell you how heavy a feeding you are giving the plant. similar to a caloric intake for humans. and you also say you are using tap water. apparently you have some pretty fair tap water but it is a good idea to KNOW where your pH is and measure it. Alot of growers will go off and buy the cheap little $20 pH meter and they can work ok. i really good reliable one should run you about $100.
An alternative to a pH meter is using pH test drops, which is what i use. (the advantage of pH drops is that they NEVER require calibration so they are almost NEVER wrong) Also, they are cheap and last a good while
Lastly since you say you are not feeing the plants any nutrients, i believe that it has grown so large that the soil can no longer sustain it and needs at least CalMag and some finishing nutrients like a M.O.A.B or ChaChing
i hope that helps (more soil growers will add to this)
Peace

Awesome thanks everyone so much for the feedback. I’ve been watching your posts and comments for awhile and I give credit to you all for what I have done so far. I think nutrients are the biggest key, my soil may not have had enough nutrients to finish off, so I need to add some to the flowering water cycle. As for being thirsty there’s no doubt that she’s over watered I found a soft spot in the soil and put my finger down and it came out well saturated and that’s four days after my last watering of around 250-500ml.
Could an issue arise from the soil or water being too cold? the tent temp is steady 23 Celsius but the tent is on a cool northern floor one of which I need slippers and socks to handle myself. Would it benefit to raise the plant off the ground to provide a warmer soil and water temp in the bottom of the pot?

Are you doin synthetic or organic man.

First let me say welcome to WP, I love organic soil, sativa strains and people that grow organically as I only use organic inputs when I use soil.
I’ll probably talk your head off man an I’ll have a few questions but from what I see she’s got either a iron or nitrogen deficiency. If you have a ppm/Ec meter can I ask what ur tap water runs at.
Also do you feed ur soil carbs/sugar or give compost teas?
And I should have asked this first but Do you plan to grow with organic inputs or are you willing to use synthetic nutes in ur soil.

Thanks for the welcome, I have been lurking for years on here and learning and reading from many of the posts and figure if anyone can help it’s the people on this site.
As for what I have going, it’s all been off the top off my head. I have no readings or anything. At this time from replies I’ll be going to get a ph tester to check my tap water, because all I know about it is it keeps my teeth healthy and it doesn’t taste like shit.
For my soil I was mislead by the title of super soil and also a little uneducated in the terms of what it takes to bring a plant to full growth.
Ultimately I want to grow organically as I live in a place where marijuana is legal recreationally and many of the suppliers products are over done chemically and many hurt more than a cigarette to smoke. So I want a simple and clean product to smoke.
Any advice you can give would be wonderful, my current plant may be out the window for help but I would love to grow more as plants are one of my passions and the only freedom we may have is being able to do things for ourselves.0 0 0 0 0 0 0 -
You done good with the super soil man. But the tap waters got to go, there are all kinds of minerals and chemicals in that shit. My best advice would be to get a small tarp and a 30–50 gallon trash can outside and collect rain and use that water, I promise you it will be the best water you have ever used except for maybe RO water that stuffs amazing.
but for this plant you could give some recharge or a compost tea and feed it something like a liquid organic fertilizer, don't use any dry kind cause that stuff takes to long to break down for where ur at in flower.

Theres an RO system at amazon name brand Geekpure that is dope AF and its 50dlrs. Fills up 100 gallons per day. I got the RO feed line split 2 ways 1 to fill my veg room res and another to fill my flower tent res. Its amazing man brings my tap from 800ppm to 30ppm. I highly recommended

I think you are doing well for a first time grower, and by reaching out now you will only get better and better with all the advice you get, cant wait how your next grow will be with the knowledge you gathered between this grow and your second grow but i bet it will be a big difference.

Well... at least you've got something to harvest ! First grows are a learning experience fosho ! A few issues you have are showing up now and very easy to fix next grow. The previous advice from the WP homies are right on too. If you don't add nutrients during the grow, the water you apply will eventually deplete what nutes you started with. That's what you're seeing now with the yellowing and slowed growth. Your water is super important too, always know what's in it. Not all tap water is bad. I will say, this plant is a great learning tool for growing with out, or very little fertilization. You'll be well ahead of the growin curve on your next grow ! Oh yeah....get rid of the "autos."0 0 0 0 0 0 0

I use tap water as well but I let it sit in the open air for at least 24 hours. The chlorine in the water will evaporate away and your plants will have an easier time absorbing the water and nutrients. I keep at least 6 1 gallon jugs and a 3 gallon jug full at all times and they usually sit for a couple days before using them. I have tried water straight from the tap and had all kinds of issues with my plants.
