pH lockout?

[Dr Seuss]

What STRAIN are you growing? Bagseed
What was the establishing technique? (seed or clone?) seeds
What is the age of your plants? 20 days since sprout
How Tall are the plants? 4.5"
What PHASE (seedling, vegetative or flower) are the plants in? veg
What Technique are you using? (SOG, SCROG etc) n/a
What size pots are you using? (Include how many subjects to pot) 16oz
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) 2/5-FFoF 2/5-chunky perlite 1/5-worm castings
What Nutrient's are you using?How much of each with how much water? 1tsp/gallon of black strap molasses
How Often? *Knowing the brand is very helpful* when it's dry
What is the TDS/EC/PPM of your nutrients used? no pen
What is the pH of the "RUN-OFF"? ~7.1
What method of pH test was administered? Using Strips? pH pen?
How often are you watering? when it's dry
When was your last feeding and how often are you feeding? n/a
What size bulb are you using? 2-42 watt CFL and 1-23 watt CFL
What is the distance to the canopy? ~2
What is your RH Factor? (Relative Humidity) 35%
What is the canopy temperature? 74F
What is the Day/Night Temp? (Include fluctuation range) 68-78
What is the current Air Flow? (cfm etc.) 2 small comp fans for lights, one large for plant section
Is the fan blowing directly at plants? kinda
Is the grow substrate constantly wet or moist? no
Is your water HARD or SOFT? hard
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Tap at first, now RO w/ just molasses
Has plant been recently pruned, cloned or pinched? no
Have any pest chemicals been used? If so what and when? no
Are plant's infected with pest's? no

I'm thinking it's a pH lockout b/c I was using tap water with a pH >7.5. I have since bought gallons of RO water from the store and have been mixing in 1tsp/gallon of molasses and adjusting it to ~6.4.

I haven't seen this in my plants before so it's kinda disappointing. There are more pictures on the second link in my sig.

Thank you in advance to any and everyone.

My plants look similar to yours. I too thought it was a pH problem, so I flushed my plants with distilled water and I'm now watering with distilled water until I can get a reverse osmosis machine.
Im using pH up + downs to keep the pH at 6.5-7 with nutrients at a quarter strength.
I just flushed a few days ago, and just watered today with the quarter strength ferts.(Bio-Bizz line)

Only time will tell if I did the right thing tho I guess.

Your plants need food man, they can't live off of black strap mollases........ your temps have to be kept stable, the purple you see on the plants is from your temps being kept cold, phosphorus is lacking from the temps and from it being not available to the plant.

now RO w/ just molasses

Since your using RO water, you must be supplimenting every watering with micronutrients. RO water has removed nearly everything from it. Your plants are very hungry and your starving them.
You need to feed them weekly.....
and since they are 20 days since sprout; have they been in this mixture since sprouting?

They need fed man, so get a feeding regimen going, get some cal-mag/ earthjuice microblast/catalyst/sensi cal. An one ofthose will work, EJ microblast lacks calcium.
You can also add a little lime to the top soil to help with lime/magneisum so all you would need is earthjuice microblast or any one of those others......

one will work fine, but as for the other nutrients you need to get a grow fert like capncrich is using, you don't have to use biobuzz, you can use something else....
You have access to a hydro shop?

im no expert, but that looks likes something other than "needing to be fed"
but i could be totally wrong...
They just look like there is a little more wrong to em than needing a feedin

 

[KABBAGE]

PH is a bit too high and as stitch said, they need something other than molasses. I personally only feed molasses in flower - molasses is used for carbs and Magnesium - 2 things that arent very useful in veg. It could possibly be an over -Mag. issue.
Regardless, Im with stitch - if nothing else, get some B-1 into those hopeful bitches..... I prolly would try to get them back to life before ramming a bunch of veg nutes down their throats. So mild feeding of possibly some Grow Earth tea, B1 and/or Hygrozyme/Sensizyme (some sort of enzyme product) This would help your plants recover faster.

 

[Dr Seuss]

I transplanted them tonight, they were slightly rootbound. Mixed a 5ml/gal PBP and 5ml/gal LK, adjusted it to 6.5, and watered them with that. I'll let you know how it turns out it a day or two.

Yup, totaly agree with ya there m8!

Dr. Seuss, the pbp amount is fine, but the LK may be burning them, given the fact you just transplanted into fresh soil, normally depending on the kind of soil, you should wait at least 2 weeks before feeding them.

"Mixed a 5ml/gal PBP and 5ml/gal LK" - sometimes I talk for nothing....

I appreciate your input.

The hyrdo store in my area closes earlier than I could make it down there today, and they're closed on the weekend. So I just cut that half, 2.5ml/gal of each... The only nutes I have are PBP grow, bloom, and LK. Would it have been better to just give them tap water at ~6.5?

 

[MynameStitch]

No your nutes you have is fine for now, just the LK amount you gave was too much on top of the pbp dosage.

I feel ya kabbage, I know exactly how you feel; it happens to me nearly everyday man.
as for the pH get some pH down from the hydro store if you can, prefably GH

your using PH up AND down ? is this normal? thought is was one or the other ?

a learner .

 

[MynameStitch]

You use it depending on how your pH is reacting, it depends on your soil pH/soiless pH, if you have a high pH use pH down, if you have a low pH you use pH up.

This goes for your run off, not your tap water.
If your tap water is high and you water often, this will cause your mediums pH to rise, when that happens you have to adjust your pH to your proper pH range.

It sounds like to me libby, he was using pH up and down messing with his pH that caused his problem and his distilled flush is what fixed it, distilled mostly, if it is properly distilled, has low pH. He may have been using a soiless mixture which is why it ended up fixing his problem, soiless pH needs to be the range of hydro 5.5 to 6.3

 

[libby]

thanks for your reply mynamstch,are you saying you ph run off and not what your feeding/watering ?

sorry if my q? is not fully understandable

will now read your ph n pest troubles....(embarassed)


cheers!

 

[MynameStitch]

Hey dude, no worries don't feel embarssed. If you are running a soiless mixture you have more control over your pH and yes you have to worry about your tap water and nutrient pH more just like hydro.
With soil you have less control over it, where the soil is what makes the final count, BUT if you use a stable pH adjuster like GH, you can control the soil pH, because the pH adjusters last longer in soil and you can control the pH better.

DEpending on the pH of the soil, if you don;t have pH adjusters you can use home remedys and such or buy stuff like dolomite lime, oyster shells and other items like peat moss. Those are all good things to use to control your pH weather it needs to be upped or put down.

Bringing your pH down is harder than bringing it up.

 

[Dr Seuss]

Thanks again to all that gave advice.

11 days later.

The 1st plant pictured is on its 6th node now and standing only 7" tall.

 

[MynameStitch]

good to see them recovering

Hope we get to see some bud shots of them when they flower out

I will definitely comeback to let you know.
