Seedlings looking sick

Hi guys. Some strange spots on my leaves and looking light green. Any idea what’s causing this? Pics attached.

Also, these are 1 month old from sprouting to the pics you see now. Seem to be growing very slow.

Thanks @Matthew420. Here’s the support ticket. Any idea what I’m wrong? Others have suggested that the soil is too hot for seedlings. It’s been around 1 month and the soil isn’t a slow release so nutes should be flushed? Any advice is much appreciated. First outdoor grow.

Strain; Type, Bag seed, ILGM… name of strain:
4 “pineapple haze” seeds and 8 “white widow”. Both feminized. Not autoflowering. Both from ILGM.

Age from Sprout: pineapple haze is 4 weeks.
White widow is 3 weeks.

Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots: soil in 5 and 10gal pots. Kellogs patio plus.

How often do you water and how do you determine when to do so? I was watering daily. Now I’ve switched to every 2-3 days. Basically let the soil dry 2 inches down and keep it moist past that.

PH of water and runoff or solution in reservoir: tap water is 7.8. With nutrients it’s 6.5. I’ve been keeping the water and nutes going in at 6.5 using “ph down”. I haven’t measured the runoff yet.

What is strength of nutrient mix? EC, or TDS: I was using “flower power” fertilizer. The “start” fertilizer is .5 gram per liter. The “grow” is .75 gram per liter. I recently purchased the General Hydroponics “grow, bloom, trace” trio. I planned on starting that soon at their standard feeding strength.

Indoor or Outdoor: outdoor. 5-6 hours of sun per day. I’ve put 2 test plants in an 8+ hour per day sun area to see if that helps.

Soil in pots, Hydroponic, or Coco / Brand and type of Soil & Size of Pots: soil in pots. Kellogs patio plus.

Light system, size and height from plants: NA

Temps; Day, Night: spring averages 70-80 day, 55-65 night. Summer can be 90-100 day, 65-75 night.

Humidity; Day, Night: we live in a low humidity area. Usually less than 20%
Ventilation system; Yes, No, Size: NA

AC, Humidifier, De-humidifier: NA

Co2; Yes, No: NO

Light system, size and height from plants: NA

Good info.

The soil doesn’t look bad to me. Maybe a little strong which brings me to point one.

I don’t think I’d be giving them nutes yet based on the additives already in that soil.

As for when to water, seedlings take minimal water. You can use a spray bottle and give them several pumps of mist onto the soil or use a pipette. Your best bet is to feel the weight of the pot dry. Once you get a feel for it, you’ll know when it’s dry. As they get bigger, it’s a little less of a concern and you can use a moisture probe. On my probe, I wait until it says dry (6" down at least) before I water.

As for PH, that “soil” actually is potting mix and I’m not sure it actually contains soil. Maybe we can get an answer on that. If there is no soil in it, it would be soilless and the PH should be 5.9. @garrigan62 and @Majiktoker, @Donaldj what are your thoughts here. I read the package and see no mention of soil being in the mix.

Tap water, let it sit open for at least 24 hours before use to let the chlorine evaporate.
Do you have a TDS meter? Might be worth knowing your tap water PPM’s.

Go with the amount of nutrients GH says to use. Many people do a couple feedings at weaker strength to start.

That’s all I can think of. I’ll re-read and see if I missed anything.

Good luck!

I zoomed in as much as I could on the package ingredients. Can you get a picture of it? I don’t see soil but don’t want to steer you wrong.

Can you read that?

Thanks @Matthew420. Great info. I don’t have an EC or TDS meter. Maybe I should invest in one. I’ll try letting the water sit open for 24 hours…maybe too much chlorine? When would you suggest starting to feed? I’m confused because GH says to start in “week 1” and I would think that since I’m at week 4, I’m due for some nutes.
Thanks for the help. Love this little community of growers!

I can understand the confusion on the feeding. The manufacturers always want you to start right away. But, seedlings don’t need much at all and your medium is already fortified so more nutrients would be overfeeding.

I use Fox Farm Ocean forest and didn’t start feeding until about a week before switching over to flower. That was 4.5 weeks but they were much bigger. This run, I’m about 4 weeks in and they’re still pretty small so it will be even longer this time before I start using nutes.

I suspect they’re growing a little slow because of light intensity. I don’t know where you are or how much direct sunlight but where I am, it’s not too intense right now.

You can get a TDS meter on Amazon for about $15. It’s good to have, particularly further along so you can measure runoff to determine if there is any nutrient buildup in the soil. Handy tool to have, sometimes a must have (if you start having problems).

And no problem, happy to help. This is the best site on the internet, IMO. :slight_smile:


Can you get where it says “Ingredients”?

It does say soil so you might be all set with the 6.5-6.6 ph. Still wouldn’t mind one of the ILGM guys to jump in.

too small to be feeding most likely nutrient burn


Thanks @Matthew420. I’ll try Fox farm next grow . Maybe it’s the amount of sun. It’s only 4-5 hrs right now. That makes sense.
@Donaldj do you think they will recover from nute burn with plain water for a while?

It likely would help you don’t typically feed seedling until they have 4-5 nodes then you start super light 1/3 dose and work your way up if they respond well


Start with Happy Frog or Light Warrior (seedlings) then go to Ocean Forest if you decide to use it. It’s strong for seedlings as well.

With my current grow, I germinated in Light Warrior. After a couple weeks, I put them in 6" pots with 60/40 Light Warrior / Ocean Forest + perlite. Next step is 5gal pots which will be Ocean Forest/Perlite/Clay Balls.

I know it seems counter intuative that they grow faster with less nutrients to start but it actually is the case. A seedling started in a nutrient rich soil will either grow very slow or die until it is large enough to need the extra nutrients it’s roots are easily burnt by them.


@Donaldj Thank you. Looks like I picked the wrong starter soil. I’ll just continue to flush with plain water and hope they recover. I figured there would be a bit of a learning curve on this grow.

@Matthew420, After reading the description for happy frog, it’s says that it’s “nutrient rich”. I thought I was trying to avoid a starter soil with nutrients? What would the difference be between the nutrients in happy frog and the kellogs patio plus that I used? Sorry for all the questions, just trying to avoid burning another set of seedlings.

I don’t know much about Kellogs but suggesting if you wanted to use Ocean Forest, don’t start in it. @bob31 can talk more of Happy Frog I think, which is less “strong” than Ocran Forest from my understanding. That said, I went with Light Warrior which is really light on the plants.

Sorry for any confusion. I was replying to you saying you wanted to use FF and wanted to give you a heads up about Ocean Forest.
