14 different strains in the system, specifically to see which does best in the UC, but dumbfounded that several turned soooo bad soooo quickly.I am not really experienced with these kinds of plants or the UC to comment, so take what I say with a grain of salt.
Is it a different strain?
The water level was only slightly dropped to the bottom of the net after the roots too place. The water level was about half way until that time.It looks to me like over-watering. I would give it time and stop changing the environment it is already stressed enough. If the roots look fine give it some time. Plants are incredibly resilient and can bounce back quickly. Did you drop the water level 50% when you went to flower?
Foiliar fed with Nitrozime and liquid light/saturator through Veg. Once a week and flipped between the two.Are you using any foliar sprays?
I should note that these had two spotted mites. Not a horrible infestation, but enough to stress the plant. All mites are gone after a round of forbid 4f, avid, floramite 4 days apart through an automizer. Since flower I have not sprayed since I planed on introducing predator mites soon to ensure no bugs at the end.I would be spraying it with neem oil and a seaweed/kelp extract. They both contain hormones and resistances that plants can use to fight diseases. Saltwater kelp is a super plant virtually immune to all known plant diseases.
Its not necessarily the dissolved oxygen that causes fall out (fall out is when your nutrients revert back to being a solid from a dissolved solid). It is the over agitation of the nutrient solution that what will possibly cause fall out. bdand over oxygenation can lead to seperation in your nutrients. They breakdown and certain mineral elements become unavailable to the plants.
Nope. No signs of rot. Good white roots on every plant.Did the roots on the one u removed look brown and dingy or smell like a pond?
I do not believe so, everything was cleaned prior to use.your temps and ppm look good there has to be contamination from older equipment that ur using or if using all new equipment there is always a chance of bad bacteria being in root products like micoriza innoculants.
I don't think I have a problem with sterility. Dropping the water level sounds logical and a possible next step.for what it's worth I've had the same transplant shock and the biggest thing that helped is DROPPING THE WATER LEVEL below the 'step'. Just like you my roots looked fab' but everything drooped. All my parameters were spot on...nutes perfect etc..plus I'm runnin' ZONE, 2 addtional air pumps and 1200 gph circulation pumps in a 40".
Agreed, they look more like over watered then anything else.I finally just realized looking at the leaf pattern' they were being ' semi drowned ' by the water level. Dropping the water level appx 3" (or more )seem to make them breath better...air to upper breather roots...and within a day or two stuff took off. I've keep the level there the entire time. Cool since it saves me water, nutes and time refilling
So, the second AP-100 is in, but a single air stone in each bucket remains. The duty was simply split, with one side managed by one pump and the other side with the other.I also agree with UCme' about too about extreme DO/turbulence, nutes and precipitating minerals. I don't think it's wise to add sooo much action and 'forget about it'.
