seedlings not growing..

[Mikell]

Well there you have it, I'll have to reconstruct my entire grow operation based on that statement

Tell me: If you induce 25% more dark period to a vegging plant = 6 hours, does the plant stretch and does photosynthesis cease ?

Yes, I've seen all the logic based arguments.

No, I'm not going to join in bickering that has been going on for years.

Something with more meat on it, por favour.

Hi rasta man

don't grow plants in clear containers the light will kill the roots..
but don't try and transplant them now they will break.

just get some solo cups and put the clear cup inside the solo and poke hole in both cups.

and like the other guys said. don't over water them!
#1 mistake of new growers. let them grow!

good luck!

 

[rasta man]

Did not know about the clear container thing when I did that...never crossed my mind that such a thing would matte... anyway. thanks for all info...think they are past critical stage for a bit..the one Black
Diesel is still having the problem with burnt leaves... nute burn the guys say...hot soil...thought I was helping...another lesson..guess I just keep putting water to her and eventually she will grow thru it if it doesnt kill... her sister, the smallest one, both now in the bigger pots, has come thru her tucked under leaf water stress stage and has straighted out her leaves..looks like she is going to be ok as well...oh yeah... still small but they are developing... the Mamba Negra on the back right is farthest along with her 4th set showing...they say to do the femming on there I think but Im not gonna be pinchin on her for a while ...the others are on their 3rd set..just an update on how they are doing.. thanks for advice.. just took them and put under the LED ..a few more seedlings popping from the bag seed..so put them under the fluro and put the fab 5 under the LED to get ready for veg in near future hopefully

FYI: I've not had a plant die from having algae on the roots(it's a mess to clean up however, so don't do it intentionally).... wrap the pot in foil... I'm vegging some plants in 64 oz peanut butter jars, I used masking tape and duct tape to 'obscure' the transmitted light. Blue masking tape seems to be the best.

IF, you have overfed the plant, you should 'flush' it with clear water until you get out the same amount of water as you put in, then do it twice more. (Observe when the new leaves get pale green/yellowish.... that's when to feed it again. Some phenos don't require as much nutrient as others, and will effectively be overfed. Feed with half the Nutes that you feed the other girls, and Carefully work up.

the peanut butter thing is cool..far as overfeeding, my mix I started them in was a little hot..I know , bad idea... anyway, just hoping she makes it thru...they are kinda little to be given much nutes I think... especially since I have a little in the soil...so they jjust get water.. I made a little tea this morning for one that was a little lighter shade of green than the others... just gave her a small dose...how long does it take a plant to show a reaction to something like giving her a drink of tea...if you happen to know

In a light mix like that probably no more than a day or two.... 12-18 hours in water.

If your light feeder isn't looking right.... don't wait.... flush her with clear water NOW. Young roots like that will die.

Don't love them to death!

If you just Have to do Something,,,, check the PH of your water.... then the PH of the run off water...

Oh, and try NOT to do what I did....experimenting is costly, if you are needing productivity.... I don't care, so I experimented frequently.

FYI on the peanut butter jars. I have plants that are approaching 2' tall.... with an airstone in each one....

Downside is at this size, they run OUT of water inside of 24 hours... doesn't seem to bother them though.

Had 8-9' plants in the GH last summer... in 5 gal. Homers,,, they were on a reservoir and a float valve to keep the water levels up in all of them. Have to watch your water PH, especially closer to harvest. I've had an AK47 that made acid 2 weeks before harvest.

That being said I'm guessing that may happen in Coco, and dirt as well. I expect that most gardeners don't check the PH of their substrate EVER.

 

[rasta man]

I have checked my soil ph and it looks to be 6.8...what Ive found though is that my homemade soil and such is turnin out to be not that easy... went with a super soil so would not have to mess much with fertilizers...decided more than one problem... one is mixing itself... dont think I did a good enuf job of mixing and there are pockets of fert. and when plant hits one its too much.. causing not only burn but lockout of nutes Im sure...plants grew slow..looked fine just short..lot of that was over nuted Im thinking..and now the sulfur colored spots with a manganese deficiency I think ...so Im of the opinion that perhaps the super soil is better left to those who are more picky in getting their mixture just right ...so I am going to go with fox farm stuff and try that as I am not having much luck with my homemade recipe... lesson learned...no bug problems.. only had the one gnat ..

 

[rasta man]

put them in these pots last nite... after reading about the manganese deficiency I gave them a good drink of water with epsom salts... hope that was correct...anyway.. have more seeds on way to start over in case these girls dont make it...

 

[rasta man]

 

[Bwanabud]

Could you shine a good flashlite on that plant, and take a couple more pics,,,,,so we can see a good color rendition ?

 

[rasta man]

dont have a flashlight.. see if this is ok.. pretty close to natural..

 

[Bwanabud]

I'm too tired to go back thru the thread

What PH water are you using, and what are the hi/low temperatures in the room ?

 

[Mike Myers]

Yea they definitely don't like something your doing, tough to tell by the pics but aside from the nute burn a few of the pics on the previous page kind of look overwatered. What size pots did you up-pot from and to?

 

[DarthFader1]

Also remember it will focus on root development first. Dont over water and relax peace sdd

This.

The first week or so is all root development then after that the plant will start to grow. Just water tiny bits at a time when the top of the soil starts to dry a bit. The key is always remembering the tiny amount of roots there are at this stage so just a little bit of water regularly is optimal. I always use a little 2 litre spray bottle for watering seedlings and cuttings.

After looking at those photos on the 15th man it really looks like you are overwatering badly. But u mentioned a super soil so who knows what is happening now. At first glance though they look badly overwatered imo

 

[2 Legal Co]

Rasta, I read a post that had manganese and epsom salt in the same sentence.

Not sure, but my epsom salts say magnesium.????

Also, I have NO personal experience with 'super soil', but I don't remember finding any dirt that had sufficient Nutes to last a full run(in top gear).

I used/use, peat and perlite to start seeds, watering with little to no nutes in it. And still have some plants show too much when transplanted into fortified soil.

And of course they will show little to no growth until they hit the wall of the pot.... or they are very happy. Some of the girls are quirky.

lol Your mileage may, of course, vary.

Mine varied so much that I went DWC..... ? It's all an experiment!

 

[2 Legal Co]

You May want to flush thoroughly with clear water and then let them dry down.

I did take the gnarliest looking one and , not having a clue as to what I was doing, put her in a pan and poured distilled water over and washing dirt away from roots...not totally but a lot...pretty scary but I thought she was gonna die anyway..put her in the bigger pot she hasnt died yet... never even drooped...hmmmm..but as most have said, the worst part was over watering and another read has led me to believe I had the led`s too close to the plant..although they never burnt, I guess it will stunt their growth.. so I have done all kinds of things wrong so far..thanks for replies...starting some new seed today..dont have the fox farm so gonna go with some promix and perlite with a little worm casting that I have had in the desktop oven trying to kill any little things that might cause damping off disease..gonna give it a good watering and not water again till its growing and leaves start to wilt from being thirsty... hahaa.. not really but close to that..far as the super soil, they havent really got to that.. I just put them in there..all their problems were before that...

sometimes what comes out of my mouth , or fingers, isnt always what Im thinking...wasnt trying to teach as Im not qualified for sure..thats just what comes out of my mouth... or fingers..manganese.. magnesium...fiddle faddle..when you get past npk Im pretty much lost..

Rasta;
After I hit the send button,,, I'm thinking, maybe there Are traces of manganese it too. lol

Freshly Baked this a.m....

P.S. For what it's not worth, I normally used 3 gals of water to flush a 3 gal pot. Unless I'm needing to up-pot anyway.

Stoner wondering; What if you added aeration to the soil/dirt/coco? Would it still be overwatered?

In DWC, the roots are Always sitting in pure water. Hmmmmm

Speaking for myself, I think my over-watering effect comes when I up-pot a smaller plant/pot to a much larger one. For example the other day I went from a 16oz cup to a 7gal smart pot and it has the effect of being over watered. I think this tends to happen if I let the plant get rootbound before uppotting and the roots get suffocated in a way. I usually let won't water them for about a week and keep them out of the direct light and off to the side and they always turn out fine. I don't recall this ever happening when I ran soil, but it has been about 5 years since I switched to coco.

@rasta I would prob follow 2legals' advice and do a nice flush and wait till they dry out a bit before starting a new regime. It can't hurt them. Basically anytime I get stumped on how I screwed up my plants, I do the same.
