This was by far the biggest plant I had and just recently the other one surpassed it and this one has looked quite sickly for some time. I was using 1/3 strength nutes then stepped up to 1/2 strength last feed, This has been going on for probably 2 weeks now and its just getting worse and also seems to be affecting how quick the plant is growing.

Pics and video included.

Save my baby girl would ya? :joint:

All help is appreciated!

Happy Growing,

Well the issue is nute burn, the reason is what we need to concentrate on. I know you probably gave the answer before but what is the medium? I know you have the FF trio nutes right? Ocalli asked a good question as well. I know your tent is outside...what are the temps in it? If it gets too cold this could cause nute lock out and cause some problems.

Love the video thing, and don't panic, the problem is not that far gone yet and for the most part, they are beautiful!

temps are in the 70-85 range. maybe high 60s some times. I water with a 7.2ph water (should I be adding something to those to lower the ph?) And I cant test it right now but tomorrow ill test the soil Ph, I only have the rapidtest ph tester for the soil and idno how accurate it is, but ill report back to yall tomorrow.

optimal ph is 6.5 to 6,8 so your deff getting a lil lockout for sure temps are fine try to keep them in around 70-80 all times

yup see this is where people fuk up so imma let u in on a secret it does and doesnt matter about water ph cause it does base off your soil ph optimal soil ph is 6.8-7.1 cause when i mix my nutes it drops my water ph from 6.8 to 5.5 but i dont raise it because when i add it to the soil it will raise the ph of my water feeding im giving ................but i also flush evey 3 weeks when in flower cause of high salt build ups from the high ppm feedings

ok, how many feedings have you given them in the past 3 weeks and how old were they when the burn first started?

lucky caught me just before i left

but what ya gotta do is flush with lets say from 6.5-6.8 ph water and flush with three times the amount of what the container is im willing to bet its a salt build up ph and lockout all in one you have all the signs

i just finished clearing mine up they were badd too now 1 month later 10x the size they where stinking to high heaven and budding

Looks like a slight Magnesium deficiency too me. plant3mg.jpeg

I doubt you have lockout or lockup, the plant looks ok otherwise. Bet your pH is just fine. Cannabis does fine in soil with a pH of 6-8, near neutral being optimal.

Magnesium (Mg) deficiency.
Magnesium deficiency will exhibit a yellowing (which may turn brown) and interveinal chlorosis beginning in the older leaves. The older leaves will be the first to develop interveinal chlorosis. Starting at leaf margin or tip and progressing inward between the veins. Notice how the veins remain somewhat green. The tips may also twist.
This can be quickly resolved by watering with 1 tablespoon Epsom salts/gallon of water. Try foliar feeding. That way the plants get all the nitrogen and Mg they need. The plants can be foliar feed at ½ teaspoon/quart of Epsom salts (first powdered and dissolved in some hot water). When mixing up soil, use 2 teaspoon dolomite lime per gallon of soil.

Dude i just took care of the same thing think you get lockouts due to wrong ph if he was feeding a 7.2 and his soil was a higher ph then hes gonna get lockouts which cause the defficiency ...........so he doesnt know his soil ph................ So how do you determine what the problem is without all info need ? You need more than just pics a doctor doesnt listen to your cough and say take this they do examinations of all facts to for a conclusion from what i see same as my prob lockout due to ph balance being off and salt buildups cause he flushed with high ph water so it high ph in the soil .........................................and there is sopmethin g not right with your chart you put up look at these shows hydro right/ soil left SO HE WAS DOING 7.2 PH CHART SHOWS RIGHT THERE HE WAS POSSIBLY LOCKING OUT N , P, Mr, Fe , AND B SOOO THERE COULD BE A HOST OF LOCKOUT ISSUES WE HAVENT EVEN SEEN YET OR CAN BE MADE WORSE BY ADDING MORE OF ANYTHING CAUSING EVEN MORE SALT BUILDUP ..............IM IN NO WAY SAYING YOUR WRONG BUT U DEFF JUMPED VERY QUICKLY TO TELL HIM TO ADD MORE OF WHAT COULD BE A POSSIBLE PROBLEM ..SOMETHING A PROPER FLUSH CANT FIX View attachment 1988358
THIS IS A HYDRO CHART

Plants are like 3months old but first month growth was stunted. Im at work right now ill do a home test but last time I did it didnt really help out went some weird color thta wasnt even on the scale. If its inconclusive ill go to some place that will test it, So since I only have the 7.2ph water availible, what do I need to do to lower the PH for the flush?

Oh and I see what your saying, so for flushing the 7.2 is an issue, but for watering its not since the nutes are lowering the Ph...Fuckin smart.
