Cupping leaves

[Fantomlimb]

Here you can see how the roots sit in the Rez a little bit.

Ya I'm no expert but I'm pretty sure the roots don't like to be submerged. In DWC there is a gap between the bottom of the pot & the water line, yours has very little gap there. That's why I asked if you could drop the water level.

I had a NFT setup, I used to run it 24/7 (my pots drained completely) in hydroton, I switched my pump to 15 minutes on & 45 minutes off and that made a world of difference.

I don't know what else to suggest perhaps someone with DWC experience will chime in.

 

[Fantomlimb]

Yea there is very little gap between the grow sponge and water if at all. Water level can and will drop as the plant uses it. I could just forego filling it back up all the way. It’s been in this system for 6 weeks and and the droop is recent. I grew regular herbs in this before hand and didn’t have major issues until months into it. I had some fungal or green algae issue that killed my dill and I think started in on my basil, but I transplanted the basil outside and it has since flourished. I religiously clean the Rez every week now to prevent that and use the Hydroguard when before I just used the aerogarden nutes for the herbs.

When I was just using the aerogarden light, I had praying leaves but since I’ve switched to the Vivosun, they’ve since stopped praying. Never heard of NFT till now, that’s a really cool set up.

This grow is mostly a test bed to see how the aerogarden can handle a plant. I already had the AG and figured why not try it. For my next grow I’m getting seeds from a medical facility in state so I’ll know strain at least. Considering I already have the nutes for hydro, does anyone recommend a grow style for that one? DWC or coco maybe?

 

[Bob Loblaw]

I'm switching to coco and mega crop, just for the simplicity of it all. No more res changes, made a sloping floor to drain into a tray got fabric bags & now it's time for me to pick 4 pretty girls to take to that dance.

Ya I would let the level drop and see if that helps.

 

[Fantomlimb]

Cool thanks man. Yea coco seems super easy. Can I use these nutes for coco?

 

[Bob Loblaw]

I'm pretty sure you can use those nutes in coco, I don't see why not. I am a novice here to be honest. I agree with the previous posters your water temps are too high = lack of oxygen in the water... oh ya you've a bubbler, still hot water don't hold oxygen very well.

I'm hoping coco is easier, it was very hard to find someone that would ship it here. The stuff I did finally get feels awful heavy to me, I'll add lots of perlite I guess for better drainage.

 

[Fantomlimb]

Unfortunately I have no way of lowering that temp. I could try small water bottle ice packs maybe

 

[Fantomlimb]

Update for anyone still following. Some of my leaves seem to be torn or missing parts. And some of them have small white tips I didn’t notice before.

If ur pH fluctuates a lot sometimes it can cause weird stuff like that, u said it’s been swinging up to 7 pretty fast?

 

[Fantomlimb]

I usually check once a day, prolly need to do twice. Yes it swings. I’ve caught it above 7 rarely but it’s happened. Usually when I check it later in the day it’s around 7. Then again, that’s usually after I add water to Rez, could be the added water is raising it. Haven’t adjusted today even after water though, I did use bottled water and not distilled as I was out. I used Essentia water. So I just checked and it’s actually at 5.5 right now. This will be the first time in awhile that I have to adjust up.

 

[Fantomlimb]

2 drops of PH up and a quick rinse of the pipette brought it to 6.0

 

[Fantomlimb]

Slight tip yellowing on new leaves

 

[Stormblessed]

5.5 is good, especially if it’s going up by itself

 

[Fantomlimb]

That’s what I was usually doing. But since it’s been going down today I want a buffer for that

 

[Stormblessed]

pH is tricky because it’s not really right or wrong, all the nutrients r taken in best at different pH levels, so 5.6 for hydro is just as close to a sweet spot as there is, but fluctuations slightly up or down aren’t necessarily a bad thing

 

[Fantomlimb]

Could it be that I defoliated immediately after I dropped the flora gro concentration?

 

[Stormblessed]

Could just b a little stressed because defol

 

[Fantomlimb]

I’ll keep on eye on it next few days, thanks all.
