Having a problem in hydro after pruning roots

I am running into the problem have tried everything cal mag just plain ro I don't understand what happen it started after pruning the roots ph is 6.0 any help would be appreciated ph pen is blue labs nutrients are gh cal mag was fed every other feeding

Why you pruning roots?

No space in 5 gallon bucket

What do you think this is from?

Ah.... Well I have no experience with root pruning or what effects may occur. She appears to be a monster for a 5 gal bucket. IMO.

What concentration of nutes, temp, humidity, light source?

I have cut back to ro water ph 6.0 I'm ftrait water right now flushing I hit it with alot of calmag no change now feeding just water for a day nutrients
Are flora gh nutrients temp 74 humidity 50 if I give it any more then light feed seems to burn the plant general hydroponic nutrients

Light source and intensity?

What nutrient, what strength, lights, temperature, humidity and medium would help others to help you.

Fwiw It looks like nutrient burn but that's just a guess without the details of your grow?

no need to prune roots in a waterfarm. do you have enough light to flower that huge plant?

Agree, no need to trim your roots.. 11 oz , under 100 days.. Read the first 12 pages of this thread..

what EC/ppm are you at? and does it drop daily? and you're sure your pH is accurate ?

you must have to fill that waterfarm twice a day as big as it is.

Once a day I clean and put new water and refill nutrients it using ro with ppm at 750 and added calmag ph 6.0 ph does not fluctuate

does your ppm fluctuate? it should be dropping each day

I'm starting to think I might be light on micro nutrients

have you looked for bugs on the leaves? you probably can't see them with the naked eye

I will look with jewelers loop
