plz help my plants are dying 2 weeks into flowering

there 2 weeks in and now there dying i was underwatering them but i fixed that and the yellow leafs arnt from nut burn or overwatering so wut could it be plzz give some cheap cures plz low on cash at the moment..

We need more information and better pics. Lights temps medium food strain ect ect. Take it out from under the growlight too for pics. I can tell yah one thing they look hungry.

hey dont look all that bad but ya more info would help to narrow down possibilities. maybe that tin foil is creating hot spots for one...good luck!

I totally agree with the tinfoil, you will cook your plants, use milar or white plastic, or panted wood for that matter as long as its white. White reflects 100% of light many reflective substitutes are expensive and reflect less then 100% (98 most of them boast) but white is way cheaper and like i said it is 100% reflective of all light colours and it never reflects heat which is always an issue in indoor growing, especially in small places. Black by the way is the essence of all light, it absorbs all light waves and thus is 0% refelctive.

i might add flat matte white reflects better then gloss(shiny)

im useing a 150 watt hps sun system,superthrive with mira grow flowering food kinda cheaped out on nutrients but money is a issue ,it stays 75-80 in there all the time fan on them constant on low,12-12 lighting,holes through out the buckets for proper drainage , no bug problem from what i can see either. plz any suggestion i love my babys i dont want em to die.

Certainly agree with this.

your babies have some kinda bad N deficiency, and little P deficiency. what do you have to feed them with? if miracle grow or some commercial stuff, if so then only use half strength every other watering. good luck

I would say your problem probably has a bit to do with the miracle grow nutrients, these are not designed for the specific needs of weed plants. Since you are in flower now you should be transitioning into some kind of bloom food from the grow food, instead you are using the same n-p-k ratio throughout the plants entire life cycle which is not what it needs. The yellow could be due to a N-nitrogen defficiency, or it could be from not having enough p or k,( which are needed more in flowering, and less nitrogen is needed), what is the n-p-k ratio of your plant food?

Edit: I just looked at your second set of better pictures, and i would say it is mostly an N deficiency which you can tell by strictly yellowing, this will happen in the begining stages of flower and throughout, because they get less light and less nitrogen, you can keep them on by adding more nitrogen. and it may be missing some micronutrients and minerals that wouldnt be in the miracle grow nutes.

just buy anything that says bloom on it. well atleast for now.

the n-p-k ratio is 15-30-15 i think

That explains the yellow, if you want more green and less yellow try a nutrient with an npk ratio where the first number is the highest, which means them most nitrogen.
