Is this mold?

[CanGroIt]

One more question. Could this be strain-related? Could this "auto-blueberrry" just be smoke-and-mirrors?

It's definitely not the plant or the strains fault.... It's operator error....

10% bleach - 90% water makes for good cleaning....warm water.... Clean every freaking thing!!!

Come to think of it, the only thing that was common to them besides the space was the nutrition with calmag. This happened within about 24 hours after the roots hit the solution. The common ingredients in both were calmag (8th recommended dose), which I was using so that I make up for the lack of it in the RO water, and the bat shit in bigbloom and the rain forest soil. Could the calmag or bat crap have been contributing factors? What is the ideal start solution for hydro? Is big bloom ok? The total PPM was only ~170 in hydro and about 50 on top of the soil. (last one because of the calmag)

Besides cleaning everything, what else could I do to prevent that disease? I'm going to go hydro bubble bucket/aeroponics/fogoponics in a brand new grow tent next.

Could the calmag or bat crap have been contributing factors? ----Doubt it....unless given at a strength too strong for the size of plant.... Seedlings in soil should have everything they need in the soil for the first couple weeks or so before having to supplement the RO water with calmag....again, this depends on the soil....


What is the ideal start solution for hydro? ----250 - 350ppms in a balanced nutrient mix....

Is big bloom ok? ----It should state on the label of the bottle if its ok for hydro....

The total PPM was only ~170 in hydro and about 50 on top of the soil. (last one because of the calmag)

Besides cleaning everything, what else could I do to prevent that disease? ----Powder mold is brought about from excessive moisture.... Plenty of air exchange should keep PM away....

I'm going to go hydro bubble bucket/aeroponics/fogoponics in a brand new grow tent next. ----:thumbsup: on the brand new tent....however I highly recommend you do a successful soil grow or two before jumping in to hydro.... You should have a solid understanding of how nutrient uptake is effected by environmental factors before going hydro.... And soil is much easier to deal with when you get yourself the right soil to begin with....

You mentioned rain forest soil....which brand exactly do you have???

Just a quick side-shot here! If you are convinced your problem is "mold", I would hedge away from a hydro grow! Due to humidity and control! Just a thought! pr

>CanGroIt: You mentioned rain forest soil....which brand exactly do you have???

Sunshine Advanced Rain Forest.

I think my main problem was air circulation in very small space (30x30x13). The duct work on my new tent should take care of that problem. Humidity here where I am is almost non-existent and the powdery mildew occurred when my RH was around 30% in soil with minimal watering of the plant in the dixie cup! Another thing I might skip on is the CFLs in addition to the 90W LED. I thought that more blue spectrum light would be good but that only compounded the heat and lack of circulation problem.

I'm going to do some heirloom tomatoes on my aeroponics/fogoponics grow first on next attempt. The system is almost built. These designer seeds are WAAY too expensive to trial and error on.

Post the strain you are interested in and what your are looking for in your medication. Ask which seeds are best for a first grow. There are many very well experienced growers here that may help you choose a "fool proof" (almost) seed. Good luck, I prefer homegrown anything as to store purchased! pr

Even if you could salvage it , it would be useless. Mold deforms it after a while. As it did to 32 of my babies in 1 hit. trashed em

The auto blueberry I'm doing in hydro has developed the same white dust with droopy leafs and yellowing after a couple of weeks. The roots look beautiful. The temperatures got to about 85-88 for about 6 hours so it's probably a source. The white powder smells like cheese.

I tried the dishsoap/baking soda/RO water/vegetable oil spray to remedy the white dust and hopefully it will recover but I can't tell if it will help.

Does anyone have any ideas or suggestions?

The PPM is about 200 and Ph is 5.8. I adjust the Ph on a daily basis.

And the humidity in your room is? You will not kill powder mildew or grey mold until you control the humidity. And forget the baking soda , if you to use a bicarb type spray then utilise *potassium* bicarb , it's a bit more efficient than sodium bicarb...........


Look this up....SNS244 , get some. If you still have it after that your next solution will unfortunately be something heavy such as Eagle 20.

Here is my advice. Shelve the soil and nutes you have. Buy a bag of fox farm ocean forest and some seedling mix - sunshine mix 4. And use that. It is just so easy. What strain are you working with again? Get something that is easy to grow this time - just about any kush, big bang, lemon skunk, something that will be forgiving. That was the key to my first successful runs b/c god knows those poor plants never should have survived let alone produce significant product! Perhaps you have good chemistry skill but otherwise, hydro is going to piss you off. Screw it up at any point and you will end up with a bucket of slimy roots. If you go hydro do lots of reading! Keep with it. It just takes a bit of perseverance.

OP...reread this ^^^^^^ , and then read it again. It's excellent advice. Don't even *think* of hydro until you can control a soil grow,

E-indoor
E-soil
E-specific medium - coconut fiber, fine bark
CSL-Soil type/brand - Sunshine Advanced Rain Forest blend - flushed it before planting
SCL-Anything you have added to the soil - RO water with an 8th calmag bringing ppm to 78 from 10
runoff pH 6.5
E-Water source -RO water
E-Source water pH - 5.5 (increased it with ph UP to 6.5)
E-Age of plant 10 days from seedling
E-Type of fertilizer - calmag supplement only
E-Rate of application (if hydro, this is your PPM number, preferably after each component is added) - with watering, once a day mist, and then once every two days mist of 1 inch of the top soil
E-Lighting source and distance from plant 2 daylight CFLs ~30 watt each 10 inches away, 90 W LED 15 inches away, enclosed in mylar walls
E-Air temperature (both day and night if you are running a dark period) 75-82
E-Air % Relative humidity 50%
E-Lighting schedule 18/6
E-Type of ventilation your room has - 6 inch fan around intake and carbon filter exhaust

Bring you temps down a bit 70-76 and bring the RH to 40% and see what happens. And ditch the coco for now. When you go to soil keep it simple.....and **make sure you don't overfeed**.

Do you have a fan on these plants? Remember that you need not only ventilation you also need air movement , get an oscillating fan if you don't have one..
