SOIL Nutrient burn or underfeeding?

[kushroom420]

Hey guys this is my second grow ive done after a few year break. And I still cant seem to keep my plants happy during flowering no matter what. I think ive done just a bit better since my last grow. My problem is my plants look like there is a problem. Now my problem is I cant tell if there getting nutrient burn, or if im just plan underfeeding them. Ive been giving them a bit more nutes this grow than compared to last and they seem a bit (by a bit, I mean only small observational things) better. But what do you guys think, I made a video and posted it on youtube. Hopefully that will show the two plants well enough, just didnt want to load the thread with 100 pictures lol.

But here is some info about my plants and how I water.

Grow room: Closet (2.5x8) (Split in two, veg and flower)
Growing medium: Soil
Pot size: 5gal
Lighting: 600watt HPS
Temp: 76-82F
Humidity: 50-55%
Light distance from canopy: 10-12~ inches
Air cooled hooded sealed off
Age since first buds: 5 1/2 weeks into flowering (Almost there!! )
Strains: 1 x Africian ZwaZulu, 1 x WiFi (White FireOg)
Soil PH: 6.7
WATER RUN OFF TEST: 1850ppm!!


I water with primary nutes one water, than secondary nutes the next, than keep going back and forth. (Primary, Secondary, Primary, Secondary, STRAIGHT WATER, Primary, Secondary, etc..., etc....)
I do water just plan tap water once and a while inbetween to try and help avoid salt buildup but I dont believe I do it enough.

Nutrients:
Primary - General Organics BioThriveBloom (2-4-4)
Last feed with primary was 1000pph

Secondary - MadFarmer mother of all bloom (0-52-32)
ZenGarden Candyman (0-0-? couldnt see last one was scratched off bottle)
Once in a blue moon epsom salt
Last feed with secondary was 840ppm

My tap water runs about 130ppm




Thank you everyone for all and any input! I very much appreciate it!

It looks like nitrogen deficiency.
Also i would like to suggest you to pass to homemade fertilizer. It isn't only a cheaper way to go, or a more natural way to do the things.. but scraps are also more forgetful. You can find diverse recipes on the web, with information about which and how to use the material you produce at home. They may have a lower quantity of nutrients, poorly distributed.. but with a drop of knowledge and initiative you can turn green and give your plant a happiness boost on her last days. And remeber, less is better! A plant without nuts can survive, yet an overfed one will most probably perish.

Thank you for your insite. Ill have to look into that! Its been a major problem both times, so I gotta find something to fix it! Really dont wanna give her any veg nutes right now but who knows? Any links to point me in the right directions?

You can collect informations from the ones you consider being useful. With these you'll be able to identify your problem and solve it by yourself, in case I've mistaken the problem.
+ I'd suggest bigger pots if you can aford them.
+ You should add some lime to the soil to lower the pH level.

Also the plant require different quantities of nutrients on vegetative and flowering stage.
Here's another guide from GWE which should help you understand the concept. Wish you good luck with your babies!

Lime raises ph of soil 😉.
