How close is the light

 

[DillyTrying2Learn]

Need way more info, what are your nutes, what's your EC/PPM, are you using tap or RO, what's your PH, are you checking your PH and EC often and recording what it is doing, that can help tell alot. Do you have any air pumps in the system, how do your roots look?

Ppm under 300 ph58.7 air stone roots look great bud sites dying new growth around it.

Also just flipped from 18-6 to 12-12

Check the suggested ppm on your nute manufacturer's feeding schedule. 300ppm seems awfully low compared to the few I've run.
I'd make sure the light isn't too close and you have enough air movement. Typically canoeing is caused by too much heat, in my experience. Raising the lights helps, and while fans don't reduce temperature they do help circulate the heat away from the area right under the lights and reduce surface temps on the plant.
My other rule for hydro is that whenever I have a plant struggling the water gets replaced and the bucket cleaned. While I don't think it will be a big help in this case, it's a good habit to form as it removes potential contributing factors to any problems you are trying to identify.

Do you have anything living on your leaves?

 

[JadedMarxist]

Looks like you sprayed something on them? And nitrogen def starting what is the humidity and temp of the water and air?

Also hard to tell from your pictures but it looks like you are starting to get the slimy snot looking goo in the roots its maybe curable but def managable. Thats a sign your water is to warm.

How do the roots feel slick at all? They should not feel slick or slimy at all!

Are you growing with a sterile res or are you using bennies?

You can easily lower your temps by getting a piece of white foam board from the dollar store and cut pieces and cover the tops of them black buckets your temps with drop a couple degrees C.
Warm water grows slime cold water wont because it holds much more oxygen which oxidises the bacteria before they can take hold plus more oxy for the roots

Bad time to flip solve your issues now to prevent self polination and seeds instead of buds shocking the plants while in flower , dont want a hermi

While I agree that cooler water holds more oxygen the effects are debatable. I had access to botanists and master growers when I worked at licensed grow ops and they told me that the cooler water/more oxygen pertained moreso to soil. Also, while you can certainly oxygenate the water it will dissipate fairly quickly as it tries to equalize with the air pressure in the atmosphere so you're going to lose most of the O². Most of the botanists preferred a higher feed temp, around 72°, to lower the viscosity of the sap in the plant to make it easier for the plant to move the nutrients through the vascular system. Because they were growing in hydro they said that the air stones provided more than enough O² for the plants so the higher feed temps worked better in their opinion.

They all told me that, for soil, better draining was more effective than oxygenated water for root O² exchange.

Roots look clean.

also, how and how often do you flush? i think that's the 1st thing i'd do is flush the shit out of them with plain water @ 5.8-6.2 ph and then start over with a fresh batch of nutes mixed @ recommended strength. it's usually recommended to flush every 7-14 days (i always err on the side of caution and flush every 7 days. it will cost me a little extra in nutes but it's well worth it in the long run imho) looks like you've got some serious nutrient lock out, whats your ph and how often are you checking it? are you using a cheap or decent ph pen? are you calibrating your ph and tds pens? very important to calibrate at least once per week (i calibrate mine during flush so that i know it's spot on for nute reset). this is getting long...hope it helps -peace-

Imho 1st prob is Too hot if hydro

 

[Jhinnovations918]

Are you running bennificals? Or are you sterile? Definitely way low on ppm for plant size and going into flower! What is the strain? What line and additives are you running? You are using tap so what is the starting ppm? I know what I would do but I need to know this first .

 

[ajpapenfuss]

Run ur nutrients a little lower than recommended
