IMO what I see has nothing to do with lights....could be wrong but unlikely....for some reason to me....stuck in my head....is your plants arent getting flooded or not draining out....something keeps telling me that is the culprit....kinda stoned so....but to get a complete meltdown like I am seeing....reminds me of what my tomato plants look like through winter when I havnt watered in like a month and everything gets all contorted and the plant starts to consume itself

and yeah what exact nutes are you using...any additives...the lineup....
also have you checked your ph meter against calibration solution....I hear its new but always make sure it is calibrated
PH perfect AN should be 5.6 ph

Fml. Just took this pic of the roots.
Please tell me is just dirty from the hydro stone sand mixing with the water and not root rot View attachment 558857

On an unrelated note-youv got a crackin set up there Danny.once you work it all out and dial it in youl be filling that space up with buds regularly.

Another suggestion.id go atleast half my grow in soil that way if you have hydro problems atleast youv got a decent half crop.
soil is very forgiving compared to hydro.

Shit no.no rez for soil.just pots n soil.unless u want to put it on a dripper because you dont have easy access to your grow.
just pop the dirt in the pot,pop in the cuts water and off you go.easy peasy lemon squeezy.no need to worry about ph(not too much anyway) root rot,rez,pumps,filters or anything.it practically grows itself in soil.true the yeilds arent as good but atleast youl get a harvest.iv grown in soil nearly 15 years and never had a room turn fucked like yours...until i tried hydro.then i had the same problem as you.i ended up useing bleach in my rez water and then i thought "fuck it" and pulled em all out and put in soil.back to basics as it were.
keep it simple mate.

all that dust leads we to believe that those rocks werent rinsed well before use
those roots def do NOT look good at all....its really early in flower so if things get worked out quickly they might survive but I believe your yield will suffer as a result
I to believe that anything over 1k ppm's is to much unless it is a strain that calls for it...every strain is differ and most strain do well between 700-900 range and NPK is good in veg with something like 3-2-4 and bloom 2-2-3... JMO good luck

yeah those roots dont look good unless your res is the same color lol.idk about all that stuff your using but i do think you should start with calibration of the meters as someone said.then i would dump that mix asap and go back to your old mix and ph to 5.6 to 5.8 and only run about 800ppm total with something simple like the heavy a & b plus maybe a lil calmag and maybe that regen a root .also i would bump your rh to 60%.how many times a day does the system flood n drain?and does the res have good oxygen/bubbles? what is your res temps?be nice to get the res to 65f at all times.what did you use nute wise during veg that had them looking good?maybe next run keep that veg mix going and just add a touch of pk boost 1 x a week.but all these dif bloom boosters being mixed these days is crazy,totally whacks out the npk ratios and most times lowers yields or causes other problems.my best hydro plants were always the lower ppm runs of 700 to 900 ppm.i had marginal success at 1400 and above.frosty,yes but yields were lower.
check those meters and dial that ph down a bit
