General Hydroponics Nutes


okay so at first i thought it was a sulfer def. so i lowered ph and added epson salt.
that didnt work
so then i thought it was an magneseum def. so i raised the ph to 70 and added more epson salt(well Mag Amp by CES witch is derived from epson salt.)

and now i have no idea none of that stuff helped

So what do you guys think

well she really dont look bad - you could remove all those leaves (and you should)

looks like N def - but how far in flower are you and what are you feeding (besides the brand) how much per gal of what nutes etc

 

[c4NN4daze]

Hmmm. How old is she? This yellowing occurs when the plant is close to harvest. There are other reasons as well but set that aside. Just give her a good flush. And when you said the pH was at 70 I am thinking you mean 7. Bring the pH down to around 6.4 or in that area. pH pens, testers, ect. do wonders. Could be over nute'n too. Some strains do wonders with no help from anything but soil. More answers and thought will come for ya. Happy Harvests. CD

like stated from above shes looks ok, just looks like she needs a little more N during her stretch. i take it she got alot bigger during it. i dont think its over nuting as i dont see any brunt leaf tips. do you have a cal-mag product? if your in soil keep your ph around 6.1-6.5. no need for the ph swings. next time you run her use ur same feed but add 5-7 ml of cal-mag plus. make sure she is nice and green before you put her into bloom.

Gh

What's your ph like?And,what medium did u say u were using?I guess I missed that.IMHO,I've always had some kinda def or problem using gh.just my 2 cents. Peace,fuzzy

fedding GH with lucas formula at about 1300 PPM right now and im in week 4 of flowering

week four of flowering. as for the ph... if you have a magnesium def. you want to raise your ph to 6.5-7.0 because magnesium is not really available in ph's lower than that where as with a sulfur def. you wan to lower your ph to below 6 so that it will be more available to the plant. Im positive its not over nute.

I do have a cal mag product from botanicare but if you have to much calcium in your soil it can block out the magnesium so i try not to use it when what i think is a magnesium def. surfaces.

im using soil..

 

[jansjukebox]

Id say it's some nitrogen defencie. I don't use that brand in specific, but I find that many brands pump up the phosphrus more and don't give enough nitrogen into flowering. cal-mag is best absorbed by plants at a ph of 6.575. Also the lighter green color of the leaves says she wants more nitrogen. Other than that she's lookin real good!

 

[motherlode]

I wanted to know how many ml's of micro and bloom are you using?

 

[CoreyB760]

6 ml of micro and 12 of bloom

maybe ill add some more micro next feeding. see if it is a nitrogen def

 

[motherlode]

6 ml of micro and 12 ml of bloom = 1300 ppm?

its been awhile - but that seems high ppm for that much nutes

when I ran the lucas dealio I would run 9 and 12 for the first 2-3 weeks of flower (depending on how much stretch) and then 6 and 16

I think thats right - Id have to dig out my old comp to double check for sure

yea i also add some cal mag(botanicar) mag amp(CES) also some humic acid and drip clean (home and garden) and my ppm meter has a .7 conversion witch makes it higher than a .5 ppm conversion meter, so that could be why it seem high.

and that is some good advice i will try the 9/12 formula thanks for the info +REP

 

[bobby-o]

bro thats not a single deficiency.. That is so clear what is going on your deficient in N and P... The yellow of the leaf indicates N shortage and that purple petiole with the dark blotchy almost fungal looking growth is a P deficiency.

 

[motherlode]

might want to try a flush first - doesnt seem like you should be that deficient so you could be locking out

 

[DaPurps]

This on one plant or all of them ?

Root Aphids ?

Assuming you are not locked out... Sounds like you know what you are doing. If no pests and not locked out they are hungry.

 

[CoreyB760]

no bugs it is a completely sealed room... i think im going to flush and then hit them hard with some nuts high in N and P

 

[Jalisco Kid]

I have seen a ton of infestations in a sealed room. If you feel they are locked out why are you going to hit them hard with nutes. What is your run off ppm? Why feed them hard till you know if they are eating? Think of your plant as yourself,if you do not feel like eating you want somebody to cram food down you,or would you like a nice tonic to help settle down your internal chemistry? JK

 

[motherlode]

JK is right about flushing and hitting them hard - you will shock the shit out of them

I should have explained myself better - when I said flus in this instance what I really meant was flus them with a 1/2 strength solution until the ppm is about in the 700 range

this will still leave them food but will wash away the built up salts that are keeping them from feeding

just flushing with ro until there is no nutes left will shock the plant and then if you hit them hard with P K you will fry them

less is more

 

[f1ydave]

the plant looks fine, its a lower leaf, trim it and move on.

 

[CoreyB760]

well i read these last posts a little to late to consider them...

but i will say the yellowing has stopped

i flushed them till the runoff was 300 ppm then nuted them at 1400 ppm with GH lucas formulat but i tweeked up the micro and bloom a touch..

the plants are taking it well i have noticed a lot of dence new growth on some and some not so much BUT the yellowing has stoped

thanks for all the impute guys i would rep your all if i could
