dwc and drip system HELP

i used flora nova bloom formula on sunday and monday i added white general purpose fertilizer... is this fertilizer shock or poison?

i think the crop is gone?

ASAP Dump and flush. Use ~ 10% of fresh nutes for the flush. This flushes more salts off than just water.

If you don't know what you are doing DON'T

FYI, 3 years ago, I started out with DWC via Drip. I am not a fan of either. You want the top of medium dry. When you run into nutrient problems you have to dump the whole thing and start over. Check out my journal for hassle free ideasi

I did the dump flush and now am considering cutting off the remaining wilted leaves....

Start Over. Next time remember, mix according to the manufacturer instructions or even less. I run my nutes half strength and the plants still look good. The amount of nutrients a plant needs is amazingly small. Yes, I killed my plants with nutrients when I was a kid too.

How do the roots look, that plant looks 100% dead / sick

Yeah very bad burn. do you own a ppm? I am doing dwc 5 gallon buckets and check my ppm everyday just because I am paranoid and so far plants are looking amazing.

it also looks like it could be mold. Try throwing a piece of aluminum foil cut into a circle around the stem. I had a top drip hydro that went all bad cuz I one, used organic soil nutrients, and two got mold and algae all over probably because the nutes were not supposed to get hit by the light ever.

Foil it not the best reflector to use, use emergency warming blanket that can be found in walmart.

DWC water should never ever be hit by light...

I meant the leca rocks that could have some nutrient content on them because of the top drip, they look kinda white in the picture

yea must of been mold because the leaves look like they had mold. and there was constant light hitting the nutrients. Initially I made an effort to prevent light from hitting the nutrients but as I would change the water/solution it became a hassle dealing with the water pump cable and let the light heat up the water.

The roots look brownish, maybe light brown. Hopefully the nutrient shock will not ruin the plant.
What is the aluminum foil/reflector paper for? Are you saying put reflectors to prevent light from touching the water basically?

How do you all keep the water temp down?

Havent got a ppm meter yet, any reccomendations?

Yea I used a heavy amount of nutrients and the following day added multi purpose 15-15-15
