Mold on roots??

Can’t tell, but it kind of looks like it. I bet if you plant them, they would be fine as it may be tricoderma

High there, my fellow growers, of course I have taken into consideration all of your help, from each single one. Yes, I have elevated the pots and indeed, they are not touchin the water at all. I was curious about the white puffy stuff, but actually thats just Mycorrhiza! I got scared first, but it is the fungi, that was inside the advanced nutrients piranha solution, that I have used in the beginning of the grow. It's in symbiosis with the roots of the plant and actually strenghtens them. Of course, the roots, which have been air pruned, do not show the signs of the fungi, since it's dead matter. I have compared the pictures on the net, with me looking through the microscope. It's the same stuff. Alas, please do not involve me in your little beefs here haha I enjoy all of your comments and advice, take them in and apply the tips in the best way I can, of course it won't be 100% copycat, that's why you people thought, that the roots were still sticking into the water. The pots are too big for the driptray and thus, are elevated on top of the tray, instead of sitting in. Maybe it's a designchoice by the manufacturer, because these weren't cheap, but I had to buy some quick, There is 5 to 6cm of space, between the edge of the pot and the bottom of the dray, on top of the one that is provided by the air pot. Next time I will still put the bottom part 1 row upward. Thank you for you kind help and consideration. Happy growing and get back to rolling joints here!

Not sure if that is mould usually see brown coloration, why don't you get some hydroguard!

Did you follow the directions or advice I gave last month for this problem? Sucks its moulding, spray it with some peroxide and kill it off them get more air under them pots, refer back tot he suggestions I made in this answer growdiaries.com/grow-questions/52697-roots-growing-on-the-tent-floor Good Luck!

I just ducked back in here since I saw someone else had put in a comment .... and that happened to be you! This page doesn't act like a chat page, unfortunately... even if you tag someone, they're not notified... You still need to get the pot permanently off the floor - just lifting it up so it "dries" is not going to do it.... how long do you hold it up? 1/2 hour? Hour? Roots have a casing on them that will keep moisture around it so while you may THINK they're dry, they probably aren't... Find a couple pieces of wood or something so the bottom of the pot is permanently off the floor. As for them turning lime green - you're not feeding them anything but calmag?! They're starving and need some regular NPK nutes at the same time. In the future, it will be good if you could link your diary to any question you may have... it's easy to do, just go to your diary and at the bottom of the page there's a box where you can ask your question... asking from there automatically links the diary and it still puts it up on this page (but it still doesn't act like a "chat"! - If you want to actually chat with someone, there's a little paper airplane icon in the bottom right-hand of every page... just search for a grower!) Good luck... get them off the floor, and for heaven's sake feed the ladies! :-D

Yes, I do pick up the runoff and let the roots dry immediately after watering, so they do prune themselves, that's why I was wondering how in the hell that white stuff appeared on there. About the lime green, you and other fellow growers have been right, i had a lockout due to a pH of 8 in my water. I have since then began to bring down the pH of my water to 6.5 before watering the plants and have cut the fertilizer by half until the (I think partially) lockout has been treated, I'm not to keen on flushing my plants.. Scared of overwatering and killing them off right then and there.

This is an airpot, yes? You've got to elevate your pot so it's not sitting on the ground/floor - the air will prune the roots back but they've GOT to be exposed to the air! Good luck! (Now what's going on with the "lime green"??)
