Help Plz! seedling leaves are drying at the tips and curling

Sounds Good.
Looking forward to seeing some serious root development on those JF's so you can up the nutes.

oh yea same here..cant wait to see what everything looks like in a week...2 weeks and those JFs should have roots coming out the bottom i bet..

Ive done some reading and it looks like the nutes I have tend to give alot of work on maintaining appropriate pH levels...sucks...think i should switch nutes?...Alot of the products I have are really good Ive read but I am thinking about changing the base nute to something else...maybe something organic...I know youll give a good honest opinion mammath...anyone else?

when you use hydro lica /clay balls as a secondary medium it is very easy for the the seedlinds to dry out,untill they have a reasonable root structure.! If your leaf tips are turning up at the ends then your issuies probaly come from PH!!!


PEACE AND LOVE!!

If your base nutes are from advanced then do not worrie.

The additives are are not absolutely nessesary.

What the diference between a strawberry grown in the ground or the tank!!

do you think i should flush my system with a no nute solution for a week? and just foliar spray my bigger plants? Do you think that would help stablize my pH a bit?

From what I've read, now that you are recirculating your PH fluctuation problems should improve.
Have they?
Also, do you mix your water/nute solution separately and then add it to your master res? This is supposed to help with PPm and PH flucts'.
As you know I don't run one of these systems. With my 'run to waste' hydro set up I use Canna Nutrients and they are fucking fantastic, never have any deficiencies, ph, or ppm probs.
Canna is designed purley for MJ and it contains a perfect blend of all elements.
But a run to waste system is totally different to what your using, and a lot simpler.
I know Canna make a nutrient specifically designed for recirculating systems, 'Canna Aqua', sounds like the shit you need, maybe you could look into that. Heres a link >>>
It's still a 2 part mix but it is all you will need, no supplements or additives are really required to get great results.
You could also look at making the nutrient aspect of your grow even simpler buy using a single part nute such as 'Flora Nova', I've heard some good reports about it.
Alternatively, you could put post a thread in the hydro section and ask for what is the best nutrient to use in a water farm.
I'm sure that sort of question should get some interesting feedback for you.
I've also read that these water farms run a bit out of wack when the plants are small and it works best with bigger plants.
Hope you get it sorted.
I don't think you should look at running just water and folia feeding.

well im for sure going to look into that canna stuff...i think they have that at my local hydro store which is convenient. The recirculating upgrade has helped tremendously with making all the pots have the same ppm and ph as the res. Still though the pH rises very quickly and I have to tweak it about 5 times a day to keep it between 5.6 and 6.2...Yes I do mix my solution seperately in 5 gallon ozarka drums and i measure everything out perfectly and pH it after mixing to 5.6...I think tonight I am going to flush the system because even with the low ppm I have right now it seems I have some nute problems with the big plants..im guessing a mag def..So yea im gunna run a flushing solution for an hour and then after put a new nute solution in...the flushing is supposed to release the nutrient bond between plant and system by removing accumulated fertilizer residue. Hopefully this will solve my problems and i can start over fresh..

Two of the three arjans last night started showing some brown spots on one or two of their leaves...one of them was not effected and looks better than ever somehow...i think its magnesium def?

Yeah, check out the Canna gear, I swear by it.
You would think that with all those supplements your plants wouldn't be deficient in anything but considering your low ppm and fluctuating PH you maybe locking out some elements too. Your still in a OK sort of range though.
Adjusting PH 5 times a day must be real hassle.
I don't think it is a Mg or Ca def' but its more like the result of some burning from the folia spray or a combination of the spray and heat from the light. Hard to tell from pick but that's what it looks like to me.
How often have you been spraying them?

Do you have good air circulation? Sounds like the plants are heating up. Back off the lights and make sure you get good airflow. I also try to rotate my pots a few times a day

its not the lights...theyre 2 and a half feet away which should be good and the plant closest to the light has no burning...I also doubt its the spray because i spray during the dark cycle and the ppm of the spray im using is only 300 ppm which is 150 ppm than the directions say online for my size plants...I dn they look a bit better and greener over night but mag def says it the leaves can still appear very green...i dn im gunna flush the system and start fresh. Flushing it should help get some of the old fert build up out of there so I can cross that off the list. Im was usig VHO by advanced nutrients for foliar spray...im now using this stuff even advanced nutrients haters like called revive( look it up)..that should take care of any mag def if thats even what i have..we will see in a few days...as long as they keep growing and dont die im not to upset..

it might have been circulation actually...the humidity has goten to about 55% and our humidifiers mist was closer to the 2 plants that were effected...i pointed the oscilating to blow constant on the light to cool the room down but that made the air more stagnant...it could be some of the leaves could not breath because of the vapor from the humidifier so some of the chlorophyll may have died from that? thanks for that idea xavier...maybe that was it...im flushing my system with flora kleen anyways right now..

Sounds like you've figured it out. Air circ' and humidity plus sparaying could look like that. Revive is good shit I believe, so looks like you've got all bases covered.
Keep us posted.

plants are looking ALOT better and the roots have doubled in growth just in the last couple days its insane...it night time right now but ill get some pics up in about 5 hrs or so

Here are some new pics...the new growth is looking better..ill get some root pics up soon...root mass almost doubled in 2 days it seems like

What do you think about upping the ppm?
They all look good and hungry.
Your going to have to juggle this for the time being because the haze needs more nutes and so do the JF's, but they may need different amounts.
What are you going to do?
Lets see those roots Wiz.
I say up it to 300ppm and that's a happy medium.

yup the haze for sure needs more nutes...im gunna make up a new solution in a day or 2 since a just made this one...probably with a ppm of 300 maybe 250 and ill continue giving the haze foliar sprays to make up for it. Right now the ppm is at 180.

Some root growth is goin on...you can see that topping these plants helped keep them shorter...think they look a little bit yellow or not as green as they should?

They're big enough to handle a lot more ppm. Roots look good.
Hows ya PH probs?

dude the pH is much more manageable now... i still adjust it about 4 times a day but i cant complain..with the water recirculating all the bucket pH's are the same as the controlling reservoir..im keeping it between 5.5 and 6...sometimes when i wake up and come check it will be as high as 6.2...

Yea I think they arent as thick and green as they could be because theyre always hungry for more nutes...especially nitrogen probably...should I double the ppm with the next solution or make 1 batch at 250 and one at 500 and gradually bring the 250 ppm up with the 500ppm solution that ill have in a 5gallon container off to the side
