Plant is dieing what can i do???

You probably just burned it from the nutes and it could also be the over watering. Its not dieing because the top is still green, if it was dieing that part would be yellow too! ALSO TRY CHECKING YOUR ph LEVEL.

ph is fine its in hydro bubble system so it cant be overwatered right? if you look closley the next biggest set of leaves that are green are starting to get a little yellow on the tips

To many ferts they are burned. Lower the ppm a bit and they should be fine.

flush the system, and try using some epsome salts, also adjust the ph if its not between 6.2-6.8, but most important get a second opinion before doing this. im still learning but thats what i would do. peace

Wait a minute hydro pH should be between 5.2-5.8. 6.2-6.8 is for soil.

right i keep it around 5.8 to 6 and so you think the top leaves will be fine also this plant is about 3 and a half weeks old if i flowered next week fri how much yeild u think i could get otta her.

Aww man very hard to know how much it will yield.

You can also use Horticulture Hydrated Lime to bring the ph up or down, just mix 1 teaspoon to 1 gallon of water.

5.5-6 (ph). 5.7 is ideal as it leaves some room for fluctuation in either direction. Make sure you test it daily, especially if your resevoir is 5 gal per plant or less. I like to use 10 per plant so the root environment is more stable. The plant looks ok though, i think its just old nute burn but to be on the safe side you should cut back some for a week or so and gradually build up again until you notice slight burn in the tips. This will give you a reference. Back off a little and your good.
