what did you foliar feed it and what nutes you using.

Humbolt vegetative and flowering additive 0-0-2 (golden tree) mix by 5%water nut solotion .
I did foliar 3 times but nothing happened ,it’s about 48 hours ago i did ma last foliar .

I just research and 90% sure it’s light burn from my Migro light.
This cob light is more powerful than i thought.
I was in 4/5 level of brightness by vegg.
Yesterday was taking to 6 .
It has 9 level of brightness and catalogue recommended go up 1 level each week up to flower stage is 9.
is it possible ?
I just put the brightness level to 1 now(6hours after starting a day light)
Also i was take it up by more 10cm by today(by the time light is get on today)

Not light burn. Looks like a Iron deficiency. Possibly caused by too much of some other nutes. Try feeding water for a few feeds then do a foliar spray with a complete nute formula about 1.0EC.

I have DWC (hydroponic too feeding) so as morning i reduce ppm around 300 and now more 200 .
I was around 1200 .i could see starting growth on some leafs by the morning

1200 is very high for this stage of growth.

This is not any hard and fast guide but is very helpful.

Seedlings, Early Sprouts 100 to 250

Early Vegging 300 to 400

Full Vegetation 450 to 700

Early Blooming 750 to 950

Full Mature Blooms 1000 to 1600

(this excludes the ppm of your water)

Yes there are a lot of guys push past this supposedly. But stick around these ranges and get bud.

Actually i can see the plant doin more well by lowering ppm now.
The issue maybe i was forgot to add grow nutrients by changing res to flower and after 1 day i add just 200/300ppm grow with was recommended feeding chart by the first week of flowering!!!?
Really I don’t think it going to lock the nutrients because i mixed them separatly and for first week chart
(3gr base ,3gr bloom ,2gr grow)
I was missing to add grow and my ppm was about 1000 .
(The recommended dosage 1100/1200ppm)
Then i add 200/300ppm only grow part to solution,before the plant seems bright green and praying for nitrogen.by the yesterday she was doing great.
Possibly I’m over ?!
(Dalkine420 nutrients)
Any idea?

Thnx budd❤
Put some RO water and reduce the ppm to 650.(so the plant hopefully can take out some nuts by the way.
Ph is 5.9 but im going to watch my ph by tomorrow and check going down or up .if going up is good things
I was on 1000 ppm by the vegg no problem at all ,i think the bloom part has more nutrients than I thought.

I mix my nutes light compared to manufacturers recommendations. I still find the PPM consistently higher than what the plants can actually use. That's the cause of my problems people get on RIU about .

It's best to use EC as PPM has different scales (64, 50, 70). so the numbers above are meaningless unless you post which scale. Regardless I have never fed my plants more than 2.0EC (= 1000PPM at 50 scale) *including* base PPM. 2.5EC (1500ppm @ 50) seems incredibly high.

Actually I’m reading alot about scales and already have 3 different ec/ph meters .
My last purchased is Bluelab combo which the manufactur also using same device on how to use the parts in YouTube channel.
50 scale is for US
70 for UK
But my bluelab also have all scales to conver.
But ppm for me is more fine than EC.
But trying to works by EC .will do some researching as well .
1ec:500ppm
0.5ec:250ppm
.
.
But every time i check out different devices they say different Ec as well.

Absolutely you right ,i read many tread and they recommend using (1/4 to 1/2)of the recommendation.
Also the plant seems to be more healthier by the time ...

I use EC and use a table to convert. But here nobody speaks EC.

My advice to people buying meters is to be sure to buy the calibration solutions with it, read the entire manual and to use it properly.

I prefer litmus paper to pH meters. Short range pH test strips.

Of cours you right
But most of expensive Ec meter are already calibrated by manufactur.
I have general hydroponic Ec/ppm calibrating solution as well as (ph10/7/4 calibrating solution )
Most important part on ec meters to keep it clean after each use by RO water and towel .
But belive me none of my EC meters showing the calibration solution as inform on the bottle.
The scales really confusing and i can not find any useful by searching .

people love to make things hard if it was up to me the world should use one scale and quit using several different ones depending on where you live or buy your products from

Dont know the kind you have but i have a 24/7 nutrient monitor made by cwp and it needs to be calibrated every now and again the cheap kind are cheap for a reason imo and I recommend calibrating them as well. They will and do drift.

If not I recommend getting some of the ph test strips to do use against the ph probe. If the probe reads 6.0 and the test strips show the proper color that is an easy way to see if your probe is on point.

I hope were talking about ph probes {i seen hotrod mention it} but ec meters should be calibrated or checked once a year I guess. I dont check my ec meter very often but the ph probe I check....Especially when I notice there has been a jump in my ph first thing I do is calibrate the probe or use test strips before BLINDLY going by the probe , jack up some plants doing that a few times.

Great advice with cross checking with PH drops or strips. With my BlueLab PH meter I calibrate it at least once a week, and leave it overnight in probe solution every couple weeks. That way it stays pretty accurate. With the BlueLab EC meter I clean it once in a while with a slightly acidic solution I make from water and PH down.
