honestly no, i dont have a calibrated meter. i am basing this off the chart on the back of my nutrient bottles. it makes sense that i have a toxic problem because of the high ppm. will final phase be a good thing to flush with. thats all i have. by biting the bullet you dont mean harvesting early do you? thanks a lot!

next time around, run 2 reservoirs and run 1 half str nutes and the other full and then you will know.

from the link,
if it was a K tox you would see signs of mg,mn,z,fe, and ca defs, not the clearly matching K def that I have linked already.

i just feel that at this ppm, a def is unlikely, but you could be very correct. im not saying youre wrong, im just not sure. dont you agree that a def. at this concentration is unlikely? or no? this is my very first hydro grow. im going to continue flush and use the time to figure out which direction to go.

Hey bud here are some pictures of a clone of mine going from a bad hydro environment to a good one only big thing I changed was R/O water and went to 25% nutrients.

is there a chance that it is a nutrient lock-out caused by the high ppm? i was also pondering this idea. also, how long should i flush for?

You're in hydro don't flush at all, just do what I told you to do. Change your res and put 25% nutrients from the recommended label instructions for your growth stage. Your PPM is way to high quit splitting hairs, go get R/O water your plants will thank you.

i know this 1 all to well, fucking advanced nutrients man, ive been having them probs with hydro. havnt seen it with the 1 dose a week additve style feeding with soil.

fucking i used 3 part, big bud carbo load, sensi zym, and like 1-2 dose of voodoo thru out the whole grow. that was all i used from them. and i didnt have 1 problem with it.

since ive been messing around with alot of the other additives they do. i have the whole fucking line, most to which are sat there turning to un usable salts (gone off) which just fucking burn the fuck out of my weed every fucking time now. and to tell the truth, i cant even be fuckt to send the bottles back, you know what the fucks that. its my plants i care for. well it just burn the hell out of them runnin at no higher then 1.6 EC, my plargon grow has some soil shots and stuff which i have been happy with using the AN with

but for fuck sake, what is up with it on hydro? i ran 2 nft's next to each other last time, 1 nft was feed with more AN additives, the other nft was left on pretty just base feeds. both ran at 1.6 EC 5.8 PH. i have all the testers and shit, and was growing with CANNA before advanced nutrients even came out here

now my crops with just 3 part, big bud, sensizym, carbo load were fine, no problems. just read that shit. the 3rd times a strike

couple pics. my current tree of life grow on nft feed with advanced nutrients 3 part line, additives and all that BS. i aint seen no shit on my nft plants like this before, until i used the advanced nutrients line of additives. sure its not 1 product for another. thats the last time.

dutch master maybe?? but i read i thing in a grow mag, with the main dude from dutch masaters saying the name "dutch master" is a piss take. there australlian. i mean come on.

house and garden for me i think. im not sure yet. but im fucking the AN additives off.

these are pics ive just taken. tree of life is a lovly strain (haze genitics from pukka seed) its just burnt and stunted now AT EC 1.6 WTF.

heres the closet thing to AN support homies. hope ya dont mind my post

Hang on a minute... U dont have an e.c/cf/ppm meter? Im an organic soil grower but i learned to grow using flood and drain hydro. That statement just sets alarm bells ringing in my head... How the hell do you know you are running a ppm of 1600? To the best of my knowledge without an accurately calibrated meter your true ppm could be way off from your "estimated" ppm that your basically guessing from the nute bottle... You have no idea of the ammount of dissolved minerals already in your tap water, u NEED to test this before adding any nutes, sorry i dont do ppm i know e.c, so if say yr water e.c is 0.6 and u require an e.c of 1.6 u need to add 1.0 of nutes, then adjust ph. my advice would be get a meter as a matter of urgency and find out what yr dealing with.

also are you keeping yr res at the optimal temp? Temp fluctuations will cause ph fluctuations. Constant low temp will stunt growth and can cause lockouts, constant high res temp promotes root rot and other pathogens and will quickly make yr solution anaerobic(oxegenless basically) which i believe can cause symptoms like your leafs rolling and curling under kinda like overwatering in soil when excess water becomes anaerobic around yr roots...Is yr res kept bubbling with an air pump and stone to keep it oxegenated or aerobic? What type of hydro system is it?
