Death is consuming my plants... help

Ive posted 3 times about this problem and no matter what i do i cant fix it. . Heres the scoop... FlordiaGirl helped me on one of my previous posts because he had the exact same problem using the exact same nutes..... that being Pure Blend Pro grow. Please refer to that post.. good stuff:

https://www.rollitup.org/marijuana-plant-problems/75536-yellowing-leaves.html

Anyways, that was three weeks ago and since then ive given them NO nutes, and flushed them 3 times... the last being a week ago when i also changed the soil to faxfarm ocean mist or something like that. I flushed in my bathtub using tap water, if that matters im not sure. Obviously the problem is not solved. After carefully examining, i thought the leaves look like a zinc overdose.... which doesnt make sense to me because i flushed them and there not getting better. The plants are in soil, 18/6 light cylcle, and im embarrassed to say they are about 3 months old now. Also my book does not say how to treat excess Zinc and at this point i have no idea what to do. I want to look at this from a new perspective since i tried 3 diffrent things over the past 6 weeks and nothing seems to help. Any suggestions? Im willing to try anything at this point because i know if this is not fixed soon i will lose the plants. Ive seen the process.... death starts from the bottom up, blackening the tips of the lower leaves... the leaves then turn yellow and eventually fall off.

Thanks for your help

Not an expert, but what is the soil pH and the pH of the water you are dropping into your girl?

I would wait until the soil dried out, go to walmart and get soem fish emulsions, and use them strong. Thats what i thik I would try first.

what the hell are "soem fish emulsions" and how do you propose they will help?

AGAIN, answer the pH question before this goes anywhere.

and next time you want to post a suggestion, explain why so we don't get dumb questions asked.

this is my third time growing and up until now ive never had major problems.. and i never paid attention to pH. I have no idea what the pH is but ill check the soil and my tap water and get back to you guys.

oh man you dont check your PH. I am no expert but that has got to be one of the most important things you can do for your grow medium of choice. You say you never checked your tap water before in other grows, well your water table might have became more acidic or more alkaline. Either way i would put a stack up that if you got your PH in the range of 6-7 in soil preferably 6.5-6.8 then you would experience a huge turn around. What about chlorine and nitrates etc.. do you atleast leave your water sit out for 24 hours to let chlorine evaporate? I use drops in my water to rid it of chlorine and excess metals etc.. like what you would use in a fish tank. Good luck, i would def get that PH right bro.

ohh thanks flordia girl... that does make sense. not your fault tho, im the dumbass for not checking pH. I will get the pH of the soil and water tommrow since i have no way to do it now. Ill post back and hopefully i'll figure it out b4 its too late. Thanks for all the help

yeah, PH is vital.

I use this PH meter, it's cheap, gives two decimal point accuracy +/- about .01, and you can easily calibrate it before use if you have some PH 7 solution and either ph 4 or 10 solution. they are both easy to find and cheap.

great item, but i gotta go stright to the hydro shop, i cant afford to wait for the shipping.

yeah once you get that PH in check you will be straight. But still like the last post said don't give too much nutes, b/c my ph is on point in my grow but i still burned my babies by not starting them on low dose. Good luck, and your like me i cant wait for online orders i just hit up the hydro shop. Thank God we have one right
