pH or something else?

Everything was going well until my last watering. I gave them tap water that I had set out for a couple of days and since then the leaves have started to curl and droop.






You can see that the first and last ones have been hit the hardest. What do I do to remedy this? Is this a pH issue, if so, should I flush with neutral water? I'm going out to get a tester/meter today. Other than this issue, how do you think the plants look for a week and a half old?

something is definitely off. walk me through your grow. what strain? what was the watering schedule once they hit soil. and tell me about your soil.

They're all bagseed in Ocean Forest. They got watered 5 days after they broke thru soil and about 3-4 days after that. They're only 2 weeks old and I was planning on feeding today.

Looks like slightly high Ph. Test the Ph of the soil before you do anything. If the Ph is too high, flushing with water won't fix it.

Ocean forest is pretty strong soil to start out in. Prob would recommend to flush and go get some light warrior. Or Happy frog worked great for me.

dont feed them and get them in bigger containers. when you get the meter test your soils run off water and then if its off flush it with 3 times as much ph'd to 6.5 water as you have soil in the container.

I finally picked up a meter, so my runoff should be testing slightly lower, correct?

Runoff when you water the plant should be close to Ph 7, equal to or slightly higher than you want your soil. If the soil is the perfect Ph (slightly acidic) then watering with plain Ph 7 water will mix with the soil and create a runoff between the soil Ph and 7. It will probably be closer to 7 because the soil needs time to change the water's Ph. If the soil Ph is off, you can water with more acidic or alkaline water so that when it mixes with the soil, it ends up equaling a better Ph value. This can create runoff that isn't quite the ideal Ph because the soil will take time to change the liquid's Ph.

If you got a soil probe-type tester, it will help to also get a cheap capsule-type test kit to verify the other's readings from time to time.

I finally tested everything and my pH seems to be in order. Can humidity issues cause the curling? I'm having some trouble keeping the humidity above 50%.

Why everyone runs to PH issues so fast?

The first picture have what looks like mold.
I'll guess the problem is that you don't have enough air circulation and your humidity.
Also humidity might be the issue. You want around 75% at this stage. Just put a clear plastic cup on top of the plants with a slight gap to allow air exchange and humidity will build up.

Its usually not just one thing that makes a plant look odd, its a bunch off things. You could have a slight N toxicity that wouldn't show in any way until the plant will have other problems.
Don't just to pH issue so fast, especially in soil.

I say just repot them into a bigger pot of a better mix (not that I know that much about american brands but people seem to not like it) and get a dome on top of all of them.
They should need a transplant by this stage.

Use dechlorinated tap water and don't pH it. Don't check you pH when you don't add nutes on a regular basis as long as your tap water is between 5.5 to 8.5

I'm sorry... but no...

The problems look to me to be related to over watering. I'm assuming you water this thing basically every day.

You need to pH balance your solution, saturate to the point of run off, then allow the soil to go dry before watering again. This should be ever 3 days or so in your small amount of soil unless the humidity is very low and the temperature is very high. Seedlings do not need high humidity, this is a myth. I am currently growing young plants at 40% humidity and high 70's temperature. Humidity domes are for clones and fools.

So, let your soil go dry. Balance the pH of some solution, water through with a good amount of run off. Biggity bam. Snippity Sam. Then start feeding with some nutrients a few days later when you lift the cups up and they are EXTREMELY light. Wait at least 48 hours, and probably closer to 72 if you can stomach it. Water in the morning.

Yea, I tested the pH of EVERYTHING and it all seemed normal. The first picture isn't mold, I was kinda buzzed and started crushing the perlite in my fingers .

I do believe it's a humidity issue because as soon as I took the wraps off of some other cups, the plants started doing the same thing. I'm going to repot in 2 gallon containers and devise some type of humidity dome and see if that helps.

Also, other than a humidifier, what can I do to up the RH? I've already got bowls and pans of water setting out to evaporate.

I don't water everyday, every 5-6 days actually. They've only been above ground 2 weeks and I've only water twice so far.

get clear plastic cups, put a small hole on top for air circulation and put them on top of your plants.
In 2 weeks TOPS they should be fine without them.
Might look down for a day but should bounce back.

In they are too big for a plastic cup use whatever you have that is clear and you can punch a small hole through.


lowering air exchange will raise the RH but can cause heat issues.

Well let me add this, when they first sprouted I had them in the party cups wrapped in saran wrap. I didn't take them out of this until they reached about a week and a half. As soon as I took them out is when this started happening. There's no way I'm going to be able to keep them under a dome the WHOLE time they veg.

they toughen up.
after mid flowering you can go as low as 5% RH and be golden.

try lowering the air exchange volume and see how it goes. watch the temps.

Thay are gettin rootbond time to tranzplant......

If you;re going from nearly 100% humidity to less than 50, you're probably shocking them. You need to lower the humidity slowly otherwise they collapse like that. For example, I use a dome to get seedlings and cutting on their feet, then after about a week I leave the dome slightly off, then more off, and finally after a few days I just take it off, and they never wilt like that. They are used to having humidity in the air, so they are probably not transporting anything to the leaves to toughen them up yet. Try putting humidity domes back on, and get them used to the lower humidity slowly. I guess I'm a humidity dome fool...

It kind of looks like over watering, but if you're watering nearly once a week I doubt that's it.
