Im just goin by the grow books. If the leaves are spotting and curling the way mg deficient plants do, then it sitting in nute water isnt going to do anything. Doing nothing means lettin it sit in the conditions that already proved unworthy. At this point, like i said, i almost have nothin to...

Thanks man, if i flush later I'll use tap, and definitely nothing else added. Guess we'll see.

Im gonna keep tryin to save this one. Sittin in ph 6.1 at ppm160, with cool bubbly water, 68° temp, 45% humidity, 2ft T5 20 inches up, and everything else i can think of to make it happy enough to bounce back if possible. Other than the foliar spray twice a day though, and maybe flushing with...

The grow bible and a few other sources suggest nutrient lockup. Mg specifically. Said that until the roots flush and open back up for business, mg in a foliar spray would help. If my only two choices are to watch it die or apply expert advice, im gonna go with apply expert advice. No offense...

Thanks for that. Image saved and link bookmarked. Is switching to soil an option to save these? Also its gotten this much worse since yesterday

I knew I'd gotten that number from somewhere. Just looked it up and it says 5.3 for cuttings in the rooter. I just upped it to 5.8. The other stuff: As far as cutting the leaves, every single tutorial ive ever seen on taking clones says to cut the leaves in half to slow down photosynthesis. The...

So, youre sayin that you cant identify the problem by the pics? Sry if i sound frustrated, but i dont have time to read a book right now. In hydro this shit happens fast. In the hour it took reading up on leaves and nutrient deficiencies and nutrient lockout, the plant got worse. I have the grow...

I have two seedlings at day 16. One started getting dark spots in between the veins on the leaves, starting from the tip and moving in. Now the second is starting it. Both have leaves curling up. When it was just the tip i tried cutting it off, since cutting leaves was ok to do with the clones i...

Is it possible to change the name of this thread? I'd prefer "How roots breathe", but idk how (or if i can) to change it

Before I answer, this "100% via DO" thing is somethin i read, NOT something i learned from any experience. Just wanna make that clear so i dont look like another repetitious lipflapper lol It's the culmination of asking a million times, then finally finding it while researching. I would guess...

Stuff like this is why I had to ask. This line specifically implies roots can breathe O2 atmospherically. Since asking this, I've learned they dont breathe atmospherically at all and get 100% O2 in water as DO, but I wanted to come back and show an example of misleading info. It's from this site...

I have two Black Dog seedlings from Humboldt Seeds, and one of them is growing oddly. It's first set of leaves got burnt tips that were snipped off. Nutrients were lowered to 200ppm low nitrogen. Second set of leaves were nice and big, but one is weird looking, with one instead of two lower...

My tapwater comes out at about 200ppm so only half of that 420 is nutes. Does that put me in the clear or should my total ppm still be lower?

I plan to use the venturi pumps on my second go around. Ive got two stones per bucket but found these tiny venturi pumps on ebay for just under $5 each so i want to put one in each bucket in addition to the stones

That sounds about right. I just flushed the cubes (actually just sat them in a pot of PH'ed water for a few mins) and took the rez down to 5.9 ph and 420ppm. One of them has had some root growth since yesterday, so not as worried today as i have been the last few. Thanks man.

Damn dude youre pretty salty for someone on a site for helping others lol i like how you didnt give me feedback but instead told me someone lied to me (i told you i read the info on THIS site) and then try to bitch at me for jumping someone else's thread. Did you forget that you were on my...

While im here, can someone review my setup for me? Water is ph 5.9, ppm 600 (combo of flora series micro and bloom), temps are cool. Water level is like a millimeter beneath the cups. Roots barely pokin outta bottom of cubes. Growth has seemed like it's been on pause the last few days but roots...

I just ordered seeds from abroad for the first time. Im in a southern state, here in the US. I wanted Black Dog from Humboldt Seeds, but they dont ship locally. Spent a week reading reviews of seedbanks before I finally decided on Linda Seeds. I opted for stealth and to keep them in original...

Ive got a few Black Dog seedlings that might be too wet. Water in homemade cloner is half an inch below cups, but the cubes stay wet from the splashing. I took one out for 12 hours to let it dry a little then rewet it. Theyve been on pause for days. I wanna say theyre gettin too wet, so should i...

I thought preflowers show around 4 to 5 weeks regardless of lighting? If so, absolutely nothing is needed except to look at the nodes up close. By the time any cuttings can show you, the plant they came from is already at least 4 to 5 weeks old http://www.growweedeasy.com/preflowers
