Hello so the soil is ffof in 3 gallon pots . He's been using GH trio at 1/2 strength week six in the feed chart every 4 days . Is this a pH problem or a too much food problem? Hes been checking the pH every watering . He's using well water .
Thanks

Fox farm’s soil is so easy to grow in just don’t add nutrients for 3 1/2 to 4 weeks just water- silica, Epsom salt,recharge etc.The soil will do the all p.h testing crap you shouldn’t have to worry about growing this weed
 
Here's an update . He quit feeding and just giving them water now .

He was feeding with GH trio and it seems like that's when issues started happening. But no more well water

High EC well water can often lock-out other nutrients, causing deficiencies. IIRC, FFOF loses its 'charge' by about 4 weeks into flower (which also tends to be a challenging time no matter what as the plants really have switched into their 'flowering needs' for nutrients by then. So this may be a 'perfect storm' of things coming together.

...I wouldn't stop feeding altogether though, with a switch of water, I'd start working on feeding again and dial that in. I didn't love Trio...it was fussy and leaves too much chance for variation in what you're doing...I moved to GH Maxi and it's been easier to dial things in.
 
Update . Looks like one is getting burnt leaves. The light is a the right distance. I'm thinking it's the well water .

What y'all think about city water ? Just let sit over night to dissipate the chlorine?

Thanks !

A couple of observations from an amateur. Take it with a grain of salt. These last couple of pictures are telling me a possible two things. Those are either nutrient lockout, or heat /light stress. Reason I say possible light stress is because the under growth looks pretty good still. seems like all your problems are on the upper branches. On the other hand (could be the photo) but your leaves are looking super dark green to me which can indicate too much nitrogen, which might tell me you might be too heavy on the nutes in general and salts are creeping up in your soil. So one of two things Lockout or light burn. Again take that with a grain of salt but I've had both and they both look very similar and a lot like yours.
 
i would take some of that bottled water and check ph/ec. then slowly water until you get some good run off. check that run off, I wager it shows rightly high EC and low PH. If so i would flush them out proper, then start back feeding with 1/3 to half nutes. With run off tests you will at least have some idea how your root zone looks. Or look up how to do a slurry test, that will give you the same info. Knowing is half the battle
 
250 ppm is high for base level water before mixing nutrients. A the issue becomes high PPM in water is heavy metals which hurt the overall usability. Even if you’re careful to only add to 700-1000ppm that base water is still heavy.

75-150ppm water if it’s well or tap in my experience. Anything higher is risky. Obviously lower is awesome I just can’t find lower than 75 from tap or well. Only clear caught rain in good catches.
 
Thanks a bunch ! Next go around he's gonna switch the water to something better. Well water is some nasty stuff haha !
