Help, I think my girls are in trouble

S= Grown:(:( in Soil
E-indoor
E-soil
E-Fox Farms Ocean Forrest (with ~ 1/2" of perelite at bottom of pail)
CSL-Fox Farms Ocean Forrest (with ~ 1/2" of perelite at bottom of pail)
SCL- added a little perelite to the FF Ocean Forrest
SCLR-3way meter (stick into soil)
E-Reverst Osmosis
E-~ 7.0
E-~4 weeks in flower
E-Type of fertilizer
E-1-600W HPS ~3' PLUS 2x 180W LED (each LED is SUPPOSED put out 3 watts each)
E-~70 degrees with lights out and ~ 85 with lights on
E- light schedual is 12/12
E-Squirrel cage

(i use a little Cal/Mag, Duece Duece, Bud Candy, Humbolt Bloom, and a lil Gravity)
I water ~ every 4-5 days with nutrients every other watering
My babies are showing some problems signs of (I think) PH problems?
PH of soil seems a bit high 7.4-7.9+
I flushed last week to drop PH of soil down (dropped to ~6.5 but is back to 7.4-7.9+)
any and all help would be greatly appriciated,
Thanks

Looks to me like a low ph issue, not enough soil in the bucket, and possibly overdosing.

CalMag and Bud Candy are redundant. Ditch one or the other. Personally, I use unsulfered molasses. Cheaper, equally effective, and widely available.

Deuce Deuce and Humbolt Bloom are WAYYY heavy in potassium. It will raise ph and restrict nutrient uptake.

Gravity, from what I've read, is a powerful additive of unknown ingredients. (kinda like Superthrive, I guess) Word is to slowly sneak-up on a maximum, as it can kill.
Being a patient, I would much prefer not to add shit of unknown origin or ingredients. Drug interractions, hormones or steroids and heavy metals are just a few of the things I'd prefer not to smoke.

Are you using a hydro nutrient (and additives) and following hydro instructions...in your soil...?

Soil feeding should be a weekly thing, usually. Did you get the directions from the bottle, or from the website? Always go with the website info. More up-to-date, and bottle instructions can often assume you are using ONLY that nutrient. The website usually gives you a better idea of plants weekly needs.


Meerry Christmas. :thumbsup:

if you ph is that high add some dolomite lime to the top of your buckets, this will drop you ph even more, I dont think Fox farm mixes theri products with to much lime other wise you would see it. I have seen people adding lime to theri bags of fox farm so I think this is your problem. However having never uses foxfarm soil, but I heat its good, I can not realy tell you about the soil.

But Lime sold at the same place you got the soil they sell it and usualy mix it for you they should have asked, if you buy just 2-4 pounds or so, even lesss you should be set, just put it on the top soil and hopefully you ph will go down. the problems are coming from nute lock out a ph of 7.5 and up is way to much I am suppriesd they are not hermied or dead, but it is a weed and will grow almost anywhere.
next time you know, add dolomite lime to your buckets before you add a plant, not the first time I have seen this.

one more thing for plants that small yo might wana try smaller buckets, it is realy easy to over water with a massive bucket like that, I usualy say bigger buckets but thats when your growing trees, for plants that size a 2 gallon pot should be enough,

rule is 1 gallon container for every month of veg.s then add a half or 3 quater to the flower.so for you a 2 gallon bucket should be more than enough. 3 gallon if you want to be safe, I see you have only half the buckets filled but smaller buckets will give you a smaller foot print int he room, means you can put more buckets.

I agree with RT.

Although, I think he meant to say your PH is high, not low? Correct me if I'm wrong.

M.S. jus' said;

"If you ph is that high add some dolomite lime to the top of your buckets, this will drop you ph even more,. . ."

That is quite incorrect.
Lime, is alkaline and will raise your PH.
That is exactly the opposite of what you wish to accomplish.

High PH >7 is alkaline.
Low PH<7 is acidic.

Clear?
Excellent, carry on.

Aloha, Y'all

Yeah. Too used to putting my fingers on 'auto-pilot'. But I was pointing out that the potassium raises ph. (not usually a good thing, especially if overdone)
Adding lime would compound an alkaline condition.
Excessive potassium increases pH

Do not use hydroponic nutes in soil, unless the nutrients specifically say it's for the dual-use. Use the proper feeding schedule, regardless. Watch for redundancies. (an act or instance of needless repetition)

My :twocents:

With RO water you loose micronutrients particularly Mg, and Ca. Cal/Mag is a great replacement or the ole Molasses routine.

But you should first repot those if at all possible. I think they are root bound, N overdose which is more because of nute imbalance/lockout with all the K you are giving them. So if it were my plants I would flush them and then repot.

ahh you guys are right, lime raises where sulfer lowers, so she does have somehting else factoring in becaeu the soil would not raise ph that much. i am goin with the flush, to get those salts out, on this one.
