I'm running an diy aeroflo rip off and having problems a couple weeks into flower. I've been running 2 part base with several additives, mainly just hammerhead anymore. I'm having a hard time deciding whether I'm starving my plants of something or over fertilizing .
Details are I run the rails at 3 minutes on and 3 minutes off or so, I tried always on but that flooded my rails due to some clogging from roots.I run a nutrient/additive level anywhere from 1500 to 2000 ppm according to the bluelab guardian. I also run a two part in veg at a level of 1600+ without burn so I can't see this being burn but I'm afraid to take it up much over 2000 ppm. see photos for issue I'm having, as I said it happens a couple weeks into flower.Thanks.issue1.jpgissue3.jpgissue2.jpg

how about a few more pics of those sad girls in the third pic. the first pic you have there they look fine maybe a little leaf curl because they are sensitive to the nutes or the ph is a tad off. the second pi looks like some old leaves that dont matter anymore, but i can't really tell from the pic.

Over fertilizing, leaves are curling down w/ burnt tip. Advanced Nutrients is one of the worst when it comes to salts in there fertilizer. Not that there is anything wrong with A.N. just be careful & go easy. Looks like your girls could use a flush.

I'm voting burnt:!:Your ppm is really on the high side for me:-P I've never go past 1200 or so :oIt could be salt build up~do you give it a little flush when watering or feeding:?:How's the ph of the run off:?:I have the feeling you might have both a ph fluctuation with high ppm cause by a build up of salts in your growing medium:clap:I think fox farm is more likely to burn especially the tiger bloom and the grow big their real strong and you mix it by the tsp where when I use Advance Nutrients I measure by the ml~

Yeah that third photo is one thats about to go into flush so it may be half assed normal . I'll get in there in a couple hours and dump yet another expensive res full on the yard( should be a healthy lawn, bud candy and all :/). flush with clearex and run nothing but base sensi 2 part at 1200 ppm or so. I've already been thru this actually I think but I didn't flush with clearex, only water. Thanks for all the advice people, I'll post update sometime possibly if it clears up. Also I have been having ph swing down, which is totally opposite of what I usually get which is a drift up.

There really is no growing medium, I'm using a diy aeroflo ripoff in 3 inch netpots(some with nothing but neoprene inserts, some with hydroton in the netpot), as I stated above I am having a drift down in the ph for some reason but I usually stay right on it and adjust daily if not more. I just put this system into operation and am thinking about buying an ebb and gro and tossing this aeroflo type design.

Looks like you're running two strains, and in order to keep one fed, the other will be burnt, and vice-versa.

Most likely the reason your pH drifts down is because your ppms are too high. They are uptaking a disproportionate amount of water in ratio to nutrient uptake......

A teaspoon is 5ml. Never heard the type of nutrient you use dictates the standard of measurement you use. I for one would really like to see some of these plants you use so many things on.:clap::clap::clap::clap::clap: And brain cells do regenerate. The process just slows with age...

Ok I've started a flush with clearex, I'll let it run for a hour or so then dump that shit on the lawn. I'm still having a hard time understanding how a plant that comes out of veg at 1600+ ppm is gonna burn at 1800 or so ppm in flower. Sounds like I will just need to wait and see if a lower nutrient level does the trick.

Most associate nute burn with Nitrogen. Phosphorous and Potassium burn and stress plants also. Even at 1600ppm with your flowering nutes I bet the levels of both are much higher than they were in your veg nutes.

No matter the cause any damaged tissue will eventually become chlorotic.(in the canopy and foliage) Thats why once an issue is identified and hopefully addressed you pay attention to new growth and the area affected too see if you have headed the problem off or if it is continuing to spread...

Yes I suppose thats true but I'm having leaves go from totally green without any sign of burn go yellow almost overnight. I've flushed and backed nutrients and additives to 1000 ppm. Lets see what happens.

I should have asked this early on since its really what threw me off, this is my first experience with this meter. a bluelab guardian has 3 different readings for nutrient strength, 4 actually if you count cf. ec/cf , tds and ppm.I know theres only one true reading and thats ec , all other readings are based on that. so my question would be what should the ec of a nutrient be for a flowering plant?

handle? do you mean the curling leaves? Good question and I really don't know the answer .I've cut back nutes and think I agree it was a user error and I ran ppm too high. Thanks for the help.
