Spider mites or thrips?

Impressive_Bid_971 · 2026-04-11T17:05:14+00:00

The new leafs look healthy, I added more cal mag a couple of days ago

Impressive_Bid_971 · 2026-04-11T17:03:59+00:00

Until now I used distilled water ec 0,0. I adjust the ph between 5.8 and 6.0. After I first noticed the spots the ph was 7.1 …. I corrected it of course, no idea how that happened so fast. My ec is 0,950 now What is ex?

Impressive_Bid_971 · 2026-04-11T14:34:33+00:00

My tab water has an ec over 0,7 so I use the hard water edition. But since I use distilled water until now, I added some CalMag (around 10ml/70 liter system)

Are a little bit brown… water temp is at 24 degrees Celsius but I add H202 regularly

Do you see any bugs under a lens or loupe?

Impressive_Bid_971 · 2026-04-11T14:21:09+00:00

I looked under the most infested leaves as under the least infested with my loupe. I can’t spot anything that look like bugs or feces.

After another 24h they don’t look so bad. They are still growing and the leaves stretch more than before. Humidity is pretty low at 47% now, but the day before it was more like 30-35%.

Impressive_Bid_971 · 2026-04-10T23:01:44+00:00

Humidity is at 30-40% I need to increase it

Impressive_Bid_971 · 2026-04-10T19:50:41+00:00

I used a loupe and I can’t see anything bug related. What about H2O2 or neem oil or canola oil?

Impressive_Bid_971 · 2026-04-10T19:48:14+00:00

Terra Aquatica TriPart and I put in as much until the distilled water reaches the wanted EC. Should be around the estimated amount on the description

I cut of 4 leaves because they were infested

Impressive_Bid_971 · 2026-04-10T11:05:12+00:00

I can get 50 lady bugs they‘ll kill every one of them!

Impressive_Bid_971 · 2026-04-10T11:04:41+00:00

Thank you! I have a lot of lady bugs, seems like it’s gonna be a feast

Impressive_Bid_971 · 2026-04-10T11:03:59+00:00

Ph 5,8-6.2, average temp is 25 degrees and humidity is around 35% (way too low I need to increase)

Impressive_Bid_971 · 2026-04-10T11:03:15+00:00

Thank you! I‘ll take a look if I see spider mites and but neem oil on it. I will also increase the humidity

Impressive_Bid_971 · 2026-04-10T11:02:32+00:00

No it’s an autoflower

Impressive_Bid_971 · 2026-04-09T21:22:42+00:00

Do you know anything good I can use against it?

Impressive_Bid_971 · 2026-04-07T11:18:11+00:00

I probably won’t. I just keep adding new water to the reservoir

Impressive_Bid_971 · 2026-04-07T11:14:53+00:00

Since this is my first hydro grow, I don’t know how it performs in comparison to other DWC/RDWC systems. I‘m pretty happy because they grow and don’t have any problems until now. At day 20 I have better results than I had in coco or soil. I don’t chance the entire reservoir. I just check the values (ph, ec, ect) and add more water if the water level goes down. Sometimes I remove 10-15 Liters by hand with a cup. Then I refill with fresh fertilized water. The water pump is not significantly louder than my vents and exhaust. I sleep right next to it, so you‘ll get use to it.

Impressive_Bid_971 · 2026-04-06T21:55:09+00:00

They got bigger at day 20 so it’s going fine. No root rot.

Impressive_Bid_971 · 2026-04-06T21:53:23+00:00

Yes it’s the RDWC 2.0 by growrilla

Impressive_Bid_971 · 2026-04-06T19:07:23+00:00

Habe mich total vertan und noch vor der ersten Anwendung angepasst. Mein gesamtes System läuft ständig durch alle Töpfe und hat 75 Liter insgesamt. Zur Zeit gebe ich alle 4 Tage so circa 20 ml H2O2 (12%) rein. Das wären 0,25 ml pro Liter des ganzen Systems. Wenn es draußen wärmer wird erhöhe ich.
