Nutrient Burn?

I went from seedling nutrients 1/4 tsp per gallon to mild vegetative 1tsp per gal with General Hydroponics, and the plant seems to be being nute burnt, so I flushed and lowered nutrients. I am growing in a 5 gallon dwc Bubbler filled with 3 gal of water now with about 1/2 tsp of flora micro, 1/2 tsp of flora grow, and 1/2 tsp flora bloom. Im growing in a tent with a 450 watt LED viparspectra and small fan blowing.
It seems like the plant is nutreient burnt, but IDK this is my first hydroponics grow. Any advice would be amazing!

are you measuring pH and EC/ppm?

I'm measuring PH at about 5.7 and I used PH Down, but did not check ppm. Im not sure exactly what ppm is though.

2.5mL of each might be too much for only 3 gals water.

how do the roots look? healthy and white?

EC or ppm measures basically how strong or weak your nute solution is.

for a plant that size, i'd go for something like 0.3 to 0.5 EC.

and you also have to measure what your water EC is too. RO water is 0 EC but well or tap can be anywhere from 0 to 0.5 Ec which you have to factor in as well.

I think they are healthy. They are just beginning to get through the net pot.

That could be the problem because I'm using tap water.

that could def be it. your tap could be high and then adding nutes makes it even stronger.

i'd pick up a EC meter ASAP.

and maybe think of switching over to RO or distilled water for the time being. it makes hydro a lot easier if you know there is nothing in your water besides what you put in it.

I'll have to pick one up. Thanks for the help!
