Plants 3 Weeks veg - Wispy New Growth - Stunted , help plz ...........

Looks like a minor Mg prob, along with nitrogen toxicity. COULD also be wet roots. Is there good drainage?

Hey jack , yeah drainage is pretty good and i have watered less than i normally do with soil as i was warned about the amount of water the cellmax cubes hold , i'm not sure if the roots have reached the pot bottom as yet as were transplanted 2 weeks ago, but what i can see look ok,
I originally thought it may have been the canna jiffy pellets i tried for the first time, i noticed clones and seedling roots struggle to break the mesh walls , i have reverted back to root riots, its just these 3 plants and it's winding me up!

I use jiffy pellets all the time without probs, so I doubt its that. I'll keep an eye here, lemme know. What ya been feeding them thats different from the last time?

You wont waste space nor energy just run 2 cycles instead of one and get an extra delayed harvest. Wasting energy and time would be bring back those clones to live given most of the apical stems are gone. Point taken about the blurt, not needed. I should have made my point clearer. Plants in that state for a perpetual grower are a no go. That's from my point of view, I'm sorry I missed yours.

Yeah all good no worries , my point is i dont want to put them in bloom as they will produce nothing in that state and will take up needed space , i dont really want to cull them , if turned around G-Bomb yields well and it's 4 weeks veg time lost but they can only stay were they are another 2 weeks....

I used some MG feed at the start as i ran out of Vitalink , reading the label on the Mg container i may have over fed and it's 6% N , could this cause that much stress Jack ?

What about vegging the clones for 2 weeks? maybe they do better than these. Lol I always argue about this kind of things with my partner.

The veg room they are in now , is awaiting clones that are in square pots and fit exactly in the space , they need 2 weeks more propagation , they cant go back , or stay , only forward into Bloom , are you getting the picture now

Ok , here are the follow up pictures , i uprooted a smaller plant and checked out the root ball , it is pretty healthy if you ask me , this plant was wisping and is stunted also,
thanks for looking,

I'm no great diagnostician but my guess would be Mg or Fe related. This is a great resource with a diagnosis chart on pages 6 and 7. http://landresources.montana.edu/NM/Modules/Module9.pdf

you have the room in flower put them in and see how they recover there does look like n toxicity hold off feeding and water sparingly they may bounce back not give the full amount your used to but not a total loss

Thanks for looking in Gastanker / Robert ,
i woke up today and i am not 1 to be defeated and i thought i must cure this today or at least discover the problem , so as Jack suggested i went over everything as i have been really busy of late with other stuff, anyway i am such an idiot , i have made a real nooby ERROR!! ,
Over the last few weeks i have changed my medium to Cellmax rockwool cubes and Hydroleca clay, using passive hydro , so to sum up , half my plants are in Soil/coco and the rest in Hydro medium ,
like a fool i have been feeding the Hydro medium plants with the Soil nute formula ,
I am guessing Hydro nutes have the lime etc micro nutes in them to compensate for the soiless mix ????????

is this my problem ???? it's the only thing i can come up with ????

Well I asked you about PH but you told me you had a vast knowledge

Blurt again ??
I did not say i had vast knowledge , "i use a ph neutral medium and rainwater i believe i replied ?

hahahaha can't help it!, if your growing hydro "stable" is a very narrow term to use friend. So your medium is most likely too alkaline right?

lol,
I dunno i'm not sure , as they are only 4 weeks old clones and only fed twice , i just do not do anything wrong ever , i follow the book always , so im guessing the nute i am using which is for soil , is not putting the micro nutes etc into my medium, so they are being fed as though they are in soil but they are not , so they are totally missing stuff!! i am a fool, this much i know , i changed medium and not nutes.

I don't think is the missing stuff but the nute buffering rising the PH. Maybe just a thought

Yeah maybe ,
Nutrients are clearly labelled seperately for hydro , soil , or coco,
I am assuming that Hydro nutes have everything in that you would normally get from soil such as limes, sulphur etc ?
am i wrong ?

When checking all sites for Cellmax grow cubes , every single 1 is saying use a Hydroponic Nutrient ?
what you think Maps ?

That's right, but it'd explain an unbalance diet not those severe symptoms IMO. Good thing is now you know how to treat.

Oh those are hydro plants? If you are using the same nute solution/water for both soil and hydro and if those are the hydro plants it could very well be a pH issue. Hydro runs much more acidic and is much much pickier about pH - soil wants less acidic water but is extremely forgiving compared to hydro. If you are watering with a pH 7 rain water and then adding basic nutrients it could easily be as simple as a pH problem.

I don't think it is the nutrients themselves but it could be possible. Water soluble nutes work for both hydro and soil - non water soluble only work for soil (but shouldn't hurt hydro plants - just won't help them as much).

Oh god now i am unconvinced i have solved the issue , They are in hydro medium , but i am only using a passive setup , feeding to the saucer , Gastanker , if you had to chose 1 , would it be underfed or overfed , i have already destroyed the worst plant , Fed 1 at half strength and left the other just flushed, to compare the 2, fook my head hurts.
