is this nute burn or normal? PLEASE HELP

i am 3weeks 4 days in flower i have cut back on my nuets useing botanicare pro bloom
soil any help please thinking of just giving them water for the next few watering

A little burnt but they look real good. If it persists flush 'em. do you ph your water?

no i buy 10 gallons of ro water from the machine thats about as far as i go did not have that much money but i think it is R.O water

http://www.amazon.com/General-Hydroponics-pH-Control-Kit/dp/B000BNKWZY/ref=pd_sim_misc_6 you may want to ph your water your in flowering they may suffer from nute lock out here's a link to a good ph tester it if you got some old books you may want to trade in do it with amazon then you could buy this just a recommendation

If your using ro water you should be adding cal/mag to it otherwise you'll end up with a def. I'm on my phone so I can't see the pics good enough but check that out.

Definitely get a ph pen, you can get them for cheap. Checking PPM would help as well. They have a little nut burn for sure, you can tell by the tips. I sometimes run mine high and the tips will burn, but yours is further into the leaf. Flush them GOOD, then start with half nutrients. You might want to lower them after that. They are looking good other than that

I agree.

#1 and worth a rep for saying so, GET A PEN!!

#2 calmag!!

#3 see how the tips have that brown-ness? When you get that and only that, you fed them JUST RIGHT. You were close, back of the feed a bit and as mentioned, flush if you see new browning.

#4 Rep lilB

You do not always need to add cal/mag if your using RO water that would depend on the nutes you use, i see no cal/mag def in your pics so the posters who say you need it are wrong. I use RO water and have done for a long time and suffer no cal/mag def, with good base nutes you dont need too add this stuff. Ease up on the nutes mate they are a little burnt other than that there looking good.

That's the thing with cal mag though, you never need it till you need it,lol. I always add during the stretch regardless, not a lot but it's in there and the issues don't come. A little preventative feeding if you will,lol.

Thats true, better to have it and not need it than need it and not have it. I have some just incase but rarely if ever need to use it. I use AN sensi with ro water and have never needed to use cal/mag even AN say you wont need it even when using RO water with sensi. Also think certain strains are more prone to cal/mag def, ive been using hesi for a short while in my coco grows and had mag def once with one particular strain when using ro water the rest are fine.

wow thank you guys i slushed them with just water today going to let them chill for a couple days and start on a reduced feeding thank you agion

I think the sensi is the key. I've never run AN but that would make perfect sens(i) lol Good luck Chronic, let us know how you make out

get a ph pen.
