Hi Stitch!
Hi kenned, I would say it is looking like nute burn with those high ppms with a 250 w bulb, or could be your hard water is locking up some nutes and causing those brown crispy spots, but I think it is nuteburn. 250 watts is not alot of light and when you read dosages on the bottles you have to know the manufacturers are running multiple 1K lights in their test gardens, so you need to dial back nutes to match your light output. The more light, the more energy to drive the plant's growth, the more nutes it can use to build new growth. The less light, the less energy, the less food required.
Let's see what Stitch says.
How's that stuff working on your thrips? I don't even know what it is. If you still have thrips then I can tell you whatever it is it isn't good enough. Spinosad (Monterey Garden Spray, etc) is a sure thing thrip killer. 1 application for me killed them all dead and never had another this crop. Completely organic and safe up to day before harvest.

Why are you not using the gh 3 part with the micros? Just a question.... I read from 10K that when you do not mix it right it can cause issues.......
What is the PPMS of your tap water?
In that first pic, is that the 250 watt hps above the plants? Those leave pics you showed looks like bleaching to me.......
What hydro setup are you running?
As for the tips in the first pic, yes that was from to high of nutrient concentration, the yellowing is from nitrogen deficiency which I would not bother fixing right right.....
You could have a cooltube or fan on a light, but if it's to close and has high lumens it causes bleaching effect to happen.
How big are these plants?
For ppm ranges to be 1100 and 1270
It looks to me to much for that size of plant, from the pic and the size of the leaves... I would put it to like 800 to 900 if the plant is under 3 feet tall.......

Stitch, his EC is 1.1 to 1.2 = 770 to 840 (on the .7 scale) or 550 to 600 (on the .5 scale)
that doesn't seem to be all that high - even for a recirc system.

He said his ppms was "my instrument ranges between 1100 and 1270"
Meaning his ppms are in that range.....
He is just figuring his EC what would be from EC to ppms....

First, is PPM the same as µS?`
the my tapwater is just about 850µS.. (i've been told that 1000 is ca. 1 EC..)
The plants are 80 cm high, but its scrog, so from the bottom to the net is 50cm and the rest is the tops.. (And theres nothing under the net..)
hmm, I kind of expected it to be light bleach, but nitrogen def...? I could get som nitrogen....?
I'm using the one part simply because I thought it was the easy thing to do..
The setup is ebb'n flow..
Yes, the first picture shows the cooltube and the plants.. They grew a bit more that anticipated, so they are a bit to big.. :S

K, the light is bleaching them even though the HPS is not strong.. it's still close and it's the lumens that is bleaching them.
Did you test your tap water with your TDS meter? That ppms you are talking about does not seem right, that is way to high and dangerous levels that is completely unsafe if that was your PPMS.
Is this tap water? You get your source of a water company?
You can give them nitrogen, but I need to know how far a long in flowering you are and how many days the breeder says the plant is ready for harvest........ 90% of breeders flowering days are completely inaccurate so you want to add on another 2 weeks from the harvest date the breeders say it is.....
So if you still have some flowering time to go 2+ weeks, add some grow nutrients that has nitrogen... if you are soon going to be harvesting in less than 2 weeks ( which it dose not look like it) but if you were, then no do not give it any nitrogen.... let it natrually yellow like cannabis does towards the end of flowering.

Okay, gotta flower them earlier next time..
I stil got like 3-5 weeks left...
Yes, the the tapwater in my area is not just hard, its very hard...
Do you think adding som grow-nutrients will be enough??
Is µS the same as PPM??

If I remember right it's another term used for scientific stuff and I do not think it's the same......
µS is measured in like lab terms I think.....
What brand of TDS meter do you have?
Yes, using some grow nutrients used for vegging can be used to fix this problem.
I would use not to much though, to much will cause stretching and delayed flowering.

my meter is Milwaukee, and I'm using GHE One part, Total grow and Total bloom.
I just added a little of the grow nutrients, hoping it will work.
The hydro system has a 10 litres res., and I'm usually just mixing half of both grow and bloom nutrients..

How much grow are you using of it?
THAT AINT NUTE BURN!!!
the LIGHT IS TOO CLOSE@!!
the first pic had a top that was 1/2 white from being BURNT! its growth was deformed like a burnt plant.
raise the light

I'm can't quite remember how much of the grow nute i've been using, but I think its about 20-25ml pr. 10 liters of water.
Well, thanks for all your help... Really great.
It seems like its just my own fault.. hehe..
So, the main problem must be too little grow-nutrients and the light too close to the plants.
I have added a little bit of grow nutes, to deal with that problem, but the problem with the light bleaching I can't really fix.
The plants grew too much, so i've raised the bulb as much as possible...
But I think that in the next grow I will use more grow than bloom fertelizer and flower earlier.
I simply got to begin to learn from my mistakes...

So a friend just wrote this to me, tell me what you think...
As you know,I have the same water as you (EC on 0.8),so you are severely underfeeding your plants and thats what you can see.
You need to step it up to atleast 2,maybe more here late in flowering.I had a good compromise around 2.2.
Remember you need to subtract the EC you have in your water from the EC your feeding with yes?
Also,the buffers in GH (I dont know what you are using) that I use first begin to work when you use enough nutes.

The only thing you are deficienct in is nitrogen, thats it. Feed some fish emulsion to fix that problem, as for the rest of the problem with the 2 pics of the leaves you showed; those are from light burn/bleaching.
Easy problem to fix as you raised the light up there, feed a little bit of nitrogen and you will fix your issue, your plants are being fed fine, just one thing you are deficienct in, and since you are not feeding them any grow..... the problem is obvious you are lacking nitrogen, or not enough nitrogen.

yes thank you Stitch!
I did get kind of confused when I read that, because the plants are doing fine except from the nitrogen thing...
Thanks again, great place to get help..!

This IS correct. 1000 micro-siemens (µs)= EC 1.0
therefore, his EC is 1.1 to 1.2 = 770 to 840 (on the .7 scale) or 550 to 600 (on the .5 scale)
Also - at 0.8 EC, your tapwater is pretty Hard! I'd consider diluting it with R.O. or as much water as you can get out of your dehumidifier.
And of course, Stich and digitalhippy are right - the white tipped bud in the middle of your pic is light bleaching from being too close to the light.
Oh, and at 6 weeks into flowering, I'd be REALLY REALLY careful about adding extra N to your feeding.

Yes, Dirt is right about the nitrogen, I forgot to mention that too much nitrogen in flowering delays it, so that is why I said to only add a little bit, half of what you would normally use in veg, or a little less depending on what you use to fix the issue.
Not only does it delay it, but it also causes it to stretch, so be very careful with how much you add; add just enough to fix the problem and thats it.
