What's wrong with these plants?

Hello everyone i have a issue i am seeking help on, i am a beginner grower and i am wondering why a few of my plants have the same issue i have provided the images below in hopes that someone can help explain or resolve my situation. a little insight i am currently in week 6 of flowering my temperature is a steady 70 degrees Fahrenheit i use aptus nutrience. the photos below are two plants same strand GSC

Looks to be nute burn. People need more info if you want help tho, nute schedule, PPM, PH of the runoff if you can test it.
I would say to flush them immediately with a very light nutrient solution, as it helps dissolve buildup better than pure water, use at least 2x the volume of the pots of water. You should have a ph meter or strips to test your water too.

i start my nutrient feed around week 5 of flower i use a 45 gallon bucket to mix all my nutrients and a sub pump to water, i water each plant for 3 minutes, when needed which is every 3 days or so the ph level is 6.0 or 6.5 everytime i flower i am using happy frog soil, and heavy 16 as a NPK

i time each plant that i water for 3 minutes i use a sub pump and a gardenhose

Yep, you have more yellow pics here than info but from what can be seen it looks like all the makings of nutrient burn. If you are a new grower that almost guarantees it.

....and no, the last thing it needs is more nutrients added to it. Ignore that crap above. ^ Those burnt leaves wont correct themselves. Flush them with 4 or 5 times the size of the pots with just plain water and learn from it....Less is more.

How big are your pots ? Do you feed them every time you water?


try feeding them once a week.

dont do 4-5 times really its a wast and ill have som1 jump on here and go no its not lol go 3 10 ltr waters will do just fine do it over a period of an hour or more so water with 10 ltr wait for it to drain and repeat 2 times after that let it dry out then start with 1/2 nutes and work your way back up to full nutes

They are just burned due to excessive nutrients.. I would skip a week of food. And lower the dose.

or what mr cloudydays rekons if u need to water just use water

Listen to the guys saying nute burn. I bet a dollar you went heavy on the bloom.

Nothing but water for a while.

being in fox farm i would just use straight water till the end of harvest any ways looks like u have 3 or more weeks left

should i start cutting off fan leaves? which ones do i cut? or should i even bother cutting them?

just let them fall off

With GSC you ease them into your feedings. Half my rooms GSC for over 2 yrs and i saw that same thing my first two runs. I figured out she likes to be fed gradually from the beginning and she'll reward you with some of the healthiest looking colorful fan leaves. She also reqiures more cal-mag & N during floweing then any other strain.
