Thought I'd give everyone an update on the situation. Upon more research, I realized that the pathogen is systemic. Water molds(oomecyte ie pythium, phytophthora) are parasites and dig deep into the plant tissue. Even if I take a clone, it is infected and will not root well and eventually...

I was able to get a compound microscope and captured the 250x zoom of water dripping from a diseased stem. I am fairly sure this is a pythium or phytophthora Oomycete. A drop of sodium hypochlorite(uc roots) does kill it as well as UV light. They get around via water and can remain dormant if...

Looks like my problem is back. However I have some ideas on how to combat this. This is the same healthy root from last post which is 4 days ago. https://www.thcfarmer.com/threads/aqua-mans-method-to-cure-root-rot-live-systems-only.122252/ Upon reading Aquaman's thread, It occurs to me that I...

In regards to the cloner, no sign of pathogen attack. They seem to be growing well, at this rate I'm pretty sure they are drinking from the roots, thus taking in nutrients and will survive. Humidity was the issue all alone. I was going to toss these clones because they weren't rooting in 12...

I am finally on track. The problem all along was humidity. Daylight was 80F/80% and that caused plants not to drink from roots, hence lack of nutrients. Night time humidity was even higher at 80-90 and caused even more issues. Since adding a dehumidifier, I've kept the rh at 55avg 24hours. I...

I see what you're saying. I was under the impression there would be some type of buffering within the dry nutrient powder. What would you recommend? I used advanced nutrient ph down before, it is much stronger than the General hydroponics one. But I am now using this one from my local...

I got the replacement Ph probe today and what a difference! The new one will get to target very fast and is very accurate. The previous one could be an amazon knockoff or it broke after a year. A working one should be very responsive and take less than 10seconds to get to target. I checked the...

Thanks for the quick reply Aquaman. I will do what you recommend and give more watering in rockwool with 1.2ec. Would you water it even if it's still pretty saturated? My fear is the roots drowning in rockwool. This is the dyna protekt, I find that it just buffers the ph and makes the solution...

Apogee Sq-520 NFT recirculate res is 10 gallons, 4ml/gal calimagic, Jacks 321, comes to 1.7 ec 5.5 ph. I have been using hydroguard 2ml/gal for the last week Rockwool dtw, hand water from a 5gallon pail i'd mix, usually same formula as above. I do suspect a ph issue, in order to rule out my...

Hey guys, a little update. I put the hydroguard in it for a week(2ml/gal). I find that while they're growing some new shoots, but eventually they become orange and also get sick. They're also not really eating or taking up enough water. Before I used hydroguard, they'd all become brown and no...

I agree with you guys, light leaks leads to a lot of problems, I need to cut out some coverings and just put it on top of the collars. You guys got me thinking and I went over my old notes. This thing did start to happen sometime around when I stopped using hydroguard and went with the southern...

The RO water that comes out the filter is at .05ec and 7.0. After I put the nutes in, it's 5.5-5.8 ph

The Ph is kept 5.6-5.8 in NFT. It can get to 6.3 after a day and then I ph down to 5.6. For Rockwool Ph, I also keep the same going in. I checked the runoff and it does go up to 6.5-7.0. Based on the thread below, Dirtbag said to not worry about the runoff ph...

Hi Blue, I did sanitize everything, even took a 3 months break. res temp would be 75-76. The reason I am trying rockwool is because it didn't touch any of the previous pumps etc, I am hand watering them and find that they are also not too healthy which leads me to think it could be something in...

Hey all, been growing NFT low pressure aero for 2 year and plants grew big and strong without any issue. Problem started to happen 6 months ago where the rooted clones would become unhealthy and roots end up turning brown and dying. You can see strands forming between roots and eventually...
