Humboldt Nutrients Nitrogen Toxicity?

I have used this trio for about a year now always to have the same problem every time. Regardless of the amount of nutrients used, which is never very much, I always have a nitrogen problem..

I cant remember the exact times of the previous plants but it seems to be around the same time. I'm in the 3rd week of flowering after sexing an unknown strain (I seem to have a lot of these seeds) and it is showing the same signs as all but one strain that I had in the past with this set of nutrients (Grow, Micro, Bloom).

The strain that succeeded was a Master Kush strain that I still was able to pull half ounce colas out of from my indoor grow. Still wasn't as good as I hoped. I think that a lot of the problems have to do with the nutrients.

I'm always checking the ph after nutrients have set for at least 3-4 hours before checking it again and then feeding them to the plants it depends on if i'm lazy or not so I might do it the next day. I fed them weekly and if any think was looking like a possible nutrient i just fed ph'd water until the problem seemed to disappear.

So here are the details, because of the past nitrogen problems I have been SUPER friggen careful not to mess things up because I want the best as possible before I switch to a different set of nutrients.

I used 1-1-1 (ml) for vegetative because I also experienced quite a bit of burn using this set with any other measurement combo i used before.

I used 1-1-2 (ml) for the transition to 12/12 after 6 weeks of vegetative growth.

I continued to used this combo for 2 weeks before I noticed some signs of nitrogen problems.

I let it continue and and time I gathered run off water the day before I used nutrients it came to 6.3- 6.5 which honestly isn't far enough off to be throwing this basic nutrient set into this much of a heap should it?

so.. gave it about 2 weeks and just this week one day it looked pretty good and appeared to have stopped spreading.. but now it is continuing again I believe and I am about to flush it again I'm just really frustrated with this always happening.

Your probably thinking about 3 questions.

Do I know its not heat stress? - Yes, I have 2 Hygrometer's inside of my little tent I check and there always accurate. One has a digital reader on the outside of the tent so I don't have to look inside

Is What Base are you using? Soil- Fox Farm Ocean Forrest - 10 gallon pot

How do you collect your run off? - lift the plant over a plastic bowl then run off the off there is enough to test with the reader.

Digital Reader is checked bi-weekly with general hydroponics ph calibration.

I am aware this is not an organic set.

Please ask me any other questions you like, I am just trying to find out if any one else had the same problems as me with this particular combo or anything involving this nutrient set and soil in general..



Thank you in advance!

If you want to use bottled nutrients then dont buy an ammended soil...one or the other.Get some promix if you want to ise bottled nutrients,or something else not loaded with ammendments already.

Or and this is what ive done with ffof soil.

Feed just plain water ,dont feed any nutrients until you start seeing lower leaves start to yellow.This may take several weeks,ffof is pretty hot soil.

What temp are you running in your tent? What wattage HPS are you running and how close to your plants are the lights?

adding more fert ffof soil is one of the more common errors people keep making. the second one is taking photos in sodium light rather than white light. we can't see plant colors in sodium.
