Checked the soil yesterday morning; too was very dry, and it was dry 3 inches down. The Ph of the degassed tap water I used was 8.3, so I added 1/8 tsp apple cider vinegar to 500 ml water and watered her again.
She’s already stunted, so I’ve been nursing her along to keep learning, and hoping to bring her to a little harvest.
My first guess is I overwatered her (soil on top was bone dry).
Second guess is PH.
Third is light/heat stress. The temps hover around 25-27° and the humidity 40-50%
I’d really appreciate the wisdom of the experienced to help me get her back to health (or give her a proper burial and start over).
Thanks!!

First grower here so not a lot of exp but managed to bring my seedling to be a beautiful flowering creature. I used a humidifer a lot, half day blowing mist on the seedling, half day on the wall near it. They love high humidity 70+ at this stage, it helps as they gather water from the leaves. Your seedling looks like its been underwatered to me, leaves look crips. I decided the make the over/under water decision by (with my limited experience) observing the leaves, crips are under and fat (full of water inside) are over. They also don’t like a lot of light at this stage I experimented with 800 PPFD and it was too much, she really liked the 500 ballpark. In fact, the light manufacturer was right I used at 25% intesity (my light is a Viparspectra XS1500). So I recommend you check and follow what yours says regarding height and intensity, and then adjust down instead of up. A fellow grower brought to my knowledge a nice mobile phone software to check PPFD, its called Photone. Happy growing, I’m sure she will thrive and provide a lot of joy.
Ah, also my watering schedule, if it helps to inspire you, (using a 15L pot mind) was very little at seedling stage. Every 4-5 days I’d drop ~300ML in a ring around the plant never at the base but 3-4 cm from it.
And thank you for the feedback! I turned the humidifier back on and raised the light. Hopefully she’ll bounce back.
I’m using a 15 L fabric pot also and watering in a ring away from the seeding. I’m going to incorporate the specifics you added to develop a better watering cycle. But, really, I think the humidity and light distance are the culprits.
I’m using Fox Farms Ocean Floor. I have the Advanced Nutrients grow, micro, bloom perfect ph set, but I haven’t added any yet. I thought it was too soon at three week and as stunted as she is. Do you think I should add some? Maybe 1/4 of what’s recommended?
Do you have a Ph and TDS meter ? If so, do a quick soil slurry and check your numbers. That way we can rule out ph. Ive seen where FF would come out of the bag in the mid 5s so it would lock out nutes during veg. If youre in a 5 gal container, rule of thumb is 30 to 45 days worth of nutes.
I used FFOF for a long time and it was great. I didn’t use it for years and when I started using it again over the last year or two I had pretty mixed results. Not sure what happened, but I have been losing faith in Fox Farm.
Hey @ChittyChittyBangin if hes using the 3 part from Advanced nutrients you definitely dont want to mess with the ph in any way. They’re made to do their own thing regardless of ph, i have one plant ph is 5.2 and the other high 6’s, both growing regardless. Ph up and down etc will mess with those nutes terribly
I would ph next feed at 6.0 to 6.2 and around 800 ppms so you don’t shock them. Get your runoff numbers near 1000 ppm in next few feeds. Check runoff weekly to make sure ph and ppm stays in line.
