Need help figuring out what going wrong with the one. My ph is in the right range and tds on third week of nutrients and is at 800 ppm.

Do you have any pictures of the leafs in question? Always post pictures in natural light.

Maybe try to cut the flash on your phone while taking your pictures.

What nutrients are you using?

@Myfriendis410 @Nicky @Watt-Sun will be able to help.

I’m not seeing anything that is of great concern. I’m also not familiar with that line of nutes. I’m sure someone will be along shortly to give you a hand.

@Covertgrower @MattyBear @Mark0427 Would y’all happen to have any advise to help a brother out?

I agree with @spyonyou I’m not seeing anything of major concern. I also haven’t heard of those nutrients before

There was leafs with darker spots that I had cut off already but the leafs in the photos are barely starting to gain the same spots I cut off. It’s a new line of nutrients I don’t believe it’s been out long I am at 80% of the recommended strength. Between the 2 plants this one is more droopy. Just hoping she’s ok🙏🏻

How far below net pot is the liquid level? Are you running a rez? What is liquid temps? What exactly is the TDS and PH of nutrient solution? How much air in the tote?

The water level is right at the bottom of net cup. Not sure what Rez is I’m a newbie to growing lol sorry? The TDS is currently at 900 now was at 800 when added nutrients currently now at 100% opps. I added nutrients to recommend tds for lotus chart then adjusted ph to 5.5. I have to 5 inch air stones in tote which is about 2.5 gallons in volume. Water temp is 72.7 room temp 80.1.

You need to have about 2” between the netpot and the water. That will help with any dropping you may have.

A res is a reservoir which some folks use as an external water source pumping water to and or from the tote you have your plants in.

Water temps need to be around 68 degrees. Much more than 72 and you’ll stand a chance of getting root rot.

I’m not using a res all the water in the totes is pumped to top feed and ok water level to high got that I will lower it and what about the water temp how do I get that down?

You can get away with just air stones once your roots extend from the netpot, provided you have a strong enough air pump. I just use my air stones to water. The water will splash up into the pot with no issues that I’ve seen.

Using top feed, you may stand a chance of problems with the stem if water is getting on them.

An option for the water is to get a water chiller and use the pump to circulate from the tote to the chiller and back. It’ll take just a little redesigning. :+1:t2:

How big is your tote?

The tote is fairly small only holds about 2.5 gallons

I did have the top feed to close to the stem as well I moved that farther back.and will lower water level Can I put the chiller in the tote with the roots? The plant is starting to show more signs of spots I mentioned in previous post

I’m sure you can grow in something like that but I do believe you will face a lot of challenges. Plants have a tendency to drink a lot of water. 1 gal per day… (each) and more.

If you can do a search on you tube on growing in dwc you will get a ton of advise.

What is up with the stem on this girl. And the spots on the leaves tho. I leave atleast 1 inch between bottom of cup and water level.

Idk I was hoping someone could tell me why she looks like that? Stem and spots? Trying to pin point where I went wrong with her cause my other one don’t look like that. This one popped before my second one so it sat in the humidity dome a little longer than it should have. That’s the only thing I can think of that I did different.
