Problems wont go away - Nirvana Chrystal Mothers, 2.5 Months + Pics

[booblebob]

Hi everyone, I have yet to post my grow on this board but my plants are not doing very well right now.

I bought some soil to start the seeds of these mothers in at the local hydro shop and they told me it's great , pH balanced and all, I can't remember the ingredients though.

The were started under some CFL's in a little cupboard with adequate ventilation, after transplant to 4 liter pots they were moved to the veg/flower closet under 2x400w grolux in cooltubes (only 1x400w in veg)

During the first 2 weeks they looked normal, I was watering with plain pH6 r/o water but the runoff was terrible- ph 7.4 - 7.6. I knew this is going to bite me in the ass soon. Due to space constraints I could not transplant into coco right away.

After starting the feeding with GHE Nutes (Lucas Formula) at 1/4 strength, 1/2 etc.. Nutes were still being locked out even though I lowered the nute solution pH to 5 or 4.8 and also 5.5 but nothing really made a diff. Runoff was high, plants were paling out and growth slow.
(This solution was diluted for soil)

High salt concentrations led me to flush all the plants but the plants didnt like it too much, especially the small B52 not pictured. It did remove some waste matter which is good though..

After transplant from 1 liter pots to 4 liter pots there was a huge recovery and green growth but then an even greater decline, this brings us to the pictures below. They are now being fed by drip in a recirculating system, full strength Lucas Formula @ 1.3 EC (0.7) The lights are on 24hrs and the drips come on twice for 13 minutes.

Weak plant, you think it's ok to clone it when so weak?

Any help would be appreciated.

hey bobble, your plants aren't looking too bad at all mate.
they are just lacking some nitrogen. I've heard the lucas formula contains enough nitrogen but maybe you want to try the original feeding plan to see if the added N will help in vegg.
It is is flowering that the lucas formula will have any effect if at all.

Also, I would not recommend switching from your soil medium to a hydro medium like coco.
That would give you so many problems you wouldn't know what had hit your plants...

One more thing, those plants are going to end up 3 times the size of those plants... You are going to have some jungle man. So imagine that plant twice as tall, then 3 times as tall, if your unlucky it will grow even taller... and bush out accordingly. Do you even have the space for that?

yes like black stated you do have a nitrogen deficiency going on

i have heard good things and bad things about lucas formula
some people swear by it some dont
but honestly nothing works for all plants

well it can but not all 2 plants take stuff the same (strain)
some require different care

so if you have different strains together and havnt grown them together before you will have problems

which is why you want one strain in a hydro system, unless you have grown the strain before and know they can take the same amount of nute requirements

you need to add some more nitrogen to your system
those are going to get huge when you stick them into flowering

call me way off base here, but those plants look like they're in far too small of pots for their size. what size pots are those? i notice that you have what seems to be one pot on top of another? it definitely looks like you've got several deficiencies and N looks like the worst. this could also be due to how root bound they must be in those pots. 4 liter seems like a very small pot for those plants (2 feet?). i would look at 5 gallon (18ish liter) pots. the fact that they cheared up when you xplanted to bigger pots should be the first clue. then they filled those pots and choked out again. also, cutting back on your nutes if they're rootbound will do more harm. i would suggest you try and transplant one and see what the roots look like. it also looks like they might be getting a touch too much water.

i personally dont like recirculating with soil.

peace

as a quick fix, assuming the dirt is dry, i would do a good flush, followed by a full strength general purpose GH flora feeding (2-2-2). people say this burns plants but it's never burnt one on me yet.

peace

Thanks for the responses,

The plants arent root bound at all and they will not be flowered either, so pot size is not a problem. Roots can be trimmed.

They have also been flushed already and right now they seem to be perking up. We will see how it goes I will keeo it updated

i hate chrystal from nirvana ,weakest bud ive grown too date.

 

[BruceLeeroy]

every time i hear of someone trimming roots i cringe lol. irrational perhaps, seems like some serious stress to me :/

I would start with your medium pH, if your pH is to high or low you will get a nutreint lock out causing your salt build ups. no matter how much nutes you feed your plants they wont be able to use them if your medium pH isn't in the right range certain nutes are not readily available. Limestone will raise your pH and peat moss will lower it.
