(P) and (K) In roots organic soil

I recently got some rooted clones on wednesday, 4 blue dream and 5 jilly beans, but a lot of them seem to be lacking nutes, phosphorus and potassium mainly, nitrogen seems to be doing completely fine, along with some turning leaves reminiscent of ph problems. I transplanted them on Wednesday into beer cups of roots organic original soil, and there growing slowly but they don't seem to be growing out of the deficiency. When I got them I originally planned on waiting 7 days of pure RO water before i started feeding, but noW I'm at day 5 and I really want to feed them some flowering nutes. How should I start introducing some phosphorus and potassium to them? Or am I just being too impatient? Also I'm running 24/0 light schedule wih temps from 68-80 and my humidity is ridiculously low at 16%. On a completely unrelated note how much does a cheap humidifier cost?

You may be being slightly impatient. If they were suffering as clones, it can take some time for them to fully revive themselves after being put in some dirt (longer than 5 days). Your using good dirt. You shouldnt need to give them anything for a couple weeks. It's already in the dirt, you may not want to mess with NPK levels yet.

I would just let them be, don't over water, don't give them nutes yet. what type of light?

If the damage from the difficiencies was pretty bad, they won't all of the sudden grow out of it. Cell damage is cell damage. It will take some time for new growth to appear and take over.

pictures would help...

im under a 1000w hortilux HPS, It wouldn't bother me if they were staying the same, it just seems like there actually getting worse.

They may need a bigger home. I'd get those in to some larger containers. An ACT would probably be advisable too.

I really don't think you're having any nutrient deficiencies at this point.

What kinda tea would you recommend? I'm kinda short on Money right now but I have a lot of roots organic liquid nutrients, and a few sample packs of dry nutrients and I was wondering if I could just make a tea out of that? The dry nutes have a huge list of ingredients with things like bat guano worm castings and chicken manure and the liquid nutes already have molasses in them. Think I could just throw some of those in with an air stone and get some more use out of them rather then just top feeding?

Those looked burnt, and locked out. over-watered, and overlit. Back the light as far away as you can, use straight water, and dont overwater.

Definitely don't think there over watered, I thought I was letting them dry out too much in between waterings. And the light is about 2 1/2 feet away from the tallest plant, think I should go further

I find things recover better under less light. 1000w hps hitting those things at 30in is too much IMO, at least for right now.

maybe try re-potting them. theyre pretty bad though. I'd almost just stop fucking with them, and go on as if they're doing fine. Just don't feed em nutes. They're burning.

Everyone is saying there burning but isn't this exactly what a deficiency looks like? The leaves literally looks just like what deficiency charts show for phosphorus and potassium deficiencies.

Also I just found this vicks steamer that's supposed to be used for raising the humidity in rooms to prevent congestion, and it raised the humidity to 30% butni wasn't sure if the steam blowing on the plants is bad?

This^. Your plant is not nutrient deficient, it's shocked as shit and a little burnt.

That's exactly what happens when you take a little clone with fragile roots out from under weak fluoro lighting (w/ little to no fertilizer), put it into a hot soil mix like Roots and stick it straight under powerful HID lighting. Been there, done that, learned from it, and it hasn't happened since.

Raise your light as high as it'll go, and give them water only until you see healthy new growth. Raising the humidity will also help slow the burning by slowing transpiration.

Good luck!

Stay away from RO water!!!! Use your tap water. It contains vital minerals needed by the plants. FORGET pH in soil. Believe me it's a non-issue unless you are in a hydroponic environment. When you water, thoroughly saturate the soil, then let it dry out. Over-watering isn't about how much water you put in, (excess will run off) but how long the roots are allowed to remain wet.

Plants work in mysterious ways... Deficiency doesn't mean the nutrients aren't there, just that the plant is having a hard time assimilating them.

An analogy... What you did was the equivalent of putting a dozen extra-spicy chicken wings in front of a baby just starting to eat solid foods. Food is there, baby is hungry. It's hard for a baby to eat when her poor sensitive tongue is burning, just like its hard for your baby clone to eat when it's poor sensitive root tips are burning.

Those deficiencies your seeing are a result of the nutrient lockout. Too much of one thing was, or not enough of something causes other micros or macros to lockout. You can't just add nutrients at this point. As that just throws off the ratios even more, and furthers the lockout - nutrients are not available. It's not that they're not there

If it was truly planted in RO dirt, and watered with reverse osmosis water, you shouldn't need to do anything else but just keep feeding It water. I'd use a little cal mag though.

i think there's more to the story though. It just looks like he hit the clones with full strength Nute solution in tapwater.

You never said what you are using as a light source.

with all due respect, your opinion on the use of tap water - you should keep to yourself. I approached this In another thread you had posted something similar in.

The fact that RO water doesn't have micros, IS WHY WE USE IT. We add the micros ourselves. Good quality micros made for high quality gardens.

Come on man... Tap water, take a look at your city's water plan.

What Dub says is true about nutrients locking each other out. I have no idea what RO dirt is, but I reiterate stop using RO water. If you are dead set on using it, most definitely get some cal/mag into the equation. And dont feed anything for a while. Your Roots Organic dirt should be able to sustain the plants for a good while. That 1K light could very well be overwhelming them. 1K lights are BEASTS!! Try a Good Floro fixture/CFLs for a while and see if that helps.

I'd have to agree with dub, tap water contains all kinds of chemicals used in water treatment. Flouride, shit loads of chlorine and chorinamine, lead..... all of which are toxic to plants and humans. And to top it off, our government is so corrupt you never know what other nasty chemicals they throw in there without telling us. I swear I've felt even more like shit everyday, since I started drinking my local tap water. You really should never use tap water unless your tap draws directly from a privately owned well. I'm gunna start buying drinking water from the grocery store from now on. Rain water is perfect for plants and humans though. I'd be feeding it to my plants and drinking it, if I lived in a state where it actually rained.

it costs $1.25 to refill a 5gal jug of RO water in front of almost any local Grocery Store. ~$125 for a 5-stage RO filter on amazon or ebay. ~$15 for a bottle of Cal-Mag that will last 2-3 grows at least, and another ~$15 for whatever other micros or stimulants you wanna add in there.

A full 1500-2000ppm diet. You added everything to. You know (for the most part) exactly what's in there mineral wise. You know it's made for plants, and not made to sustain the harsh realities of tap water in a urban infastructure.

Sure add 500+ ppm of city regulated water into your 1500-2000ppm nutrient regime. See what happens next. Enjoi

we're way off topic now, but this is important


btw, RO dirt = Roots Organic dirt

I'm originally from Key West. The majority of our water there comes from Miami (and it's horrible there) and gets to us through 150 mi of the Fla Keys aqueduct. THAT is some fucked up water. That I would not use under any circumstances for anything other than bathing. I hear that SoCal is pretty bad as well, being alkaline as hell.
I'll not get into a dispute over the toxicity of municipal additives, however I have proven quite satisfactorily to myself that my tap water here in E. Tenn is perfectly fine for my plants. I stopped having any problems with deficiencies, most notably the Ca and Mg deficiencies that decimated my first 2 grows, since reverting to tap.
Hell, even rain water (here at least) has WAY elevated levels of sulphur dioxide, nitrogen oxide and a veritable HOST of other pollutants, besides being acidic as all hell. Maybe rain water in Montana or the outback of Australia is pretty pure, but not many places on earth any more have that luxury

Dub is right in the essence of what he says. I just don't get THAT anal anymore (I used to be), I just figure that at some point I hit a point of diminished returns on my efforts. I still make my own soil rather than use the native soils here in the mountains since after having it tested, I found heavy metal toxins in it from several different locations.

But we are way off track here, sorry for the diversion. OP, Try Epsom Salts!
