Help! My plants look worse every day!

PICS TO FOLLOW

I really hope someone can chime in and help me out, this is my first time and while I look forward to many years of learning and hopefully helping others, I also count on this to treat my pain cant afford a total failure. The leaves seem to be spotting and turning yellow from the bottom up, the oldest leaves dying off first. It looks a little the pics Ive seen of nitrogen deficiency, so maybe I up the dosage of my nutes? Im at a loss...

At first look are they rootbound Maybe time to go to larger pots . A PH meter is your friend believe me .... We use the Bio Canna as well with great results. Remove those yellow leaves transplant to bigger pots and check your PH you will be fine .. That Rhizotonic is some great stuff as well ...

 

[JPinkman]

When they dry out from this last watering Ill try to check the roots. Is there a PH meter youd recomend for soil? Or should I be checking water or both?

 

[Jedthedog]

I have tried a bunch of meters and had the best luck with Oakton product details

 

[JPinkman]

Thanks!

First of all 4 wks is way to long to be in a solo cup.
This may be true that your soil has buffer agents and the like in it to control pH, but its a good idea to keep an eye on pH for sound mind as it is critical in maintaining a healthy garden.
Hanna and Milwaukee make solid meters.

 

[JPinkman]

Ok thanks guys. Ill get them into 1 gals asap and spend the day researching ph meters.

With the size of your plants it's most likely nitrogen deficiency they have a yellowish color and you're already getting yellow leaves and having to pull them is it starting from the bottom or from the top

 

[JPinkman]

From the bottom. Id already decided to up my nute dose for the next feeding, but that wont be for a few days

 

[Imhigh85]

Sounds like you have two problems nitrogen deficiency rootbound if you change pot and then start watering again it's very possible it will up your nitrogen level

 

[JPinkman]

Thank you so much. That is on my to do list for the day.

 

[Imhigh85]

If you have anymore questions just ask

 

[JPinkman]

Ill post an update once I get the work done. I was planning on adding bat guano to the mix at the 1 gallon change, should I still do this?

 

[Imhigh85]

Start with a low dose and move up very slowly don't want to shock the plants

I agree with what everyone else said. In addition, you have 13 plants in a 4x4x6.5 tent? You'll need FAR more room especially once you get them in say 2.5 gallon pots. Are you planning on moving outdoors?

Was thinking the same thing... 4 weeks in solo cups- they are rootbound for sure!
I don't worry much about ph with my soil and I also use gh nutes and calmag in my soil.
Paling lower leaves, to me, would normally indicate calmag deficiencies but as they are in tiny cups at 4 weeks, I just think they are choking to death.

Even if it's not the issue, it's time to uppot.. I like fabric pots myself and do 5 or 7 gallon. Just better to move them once and they will love you for it.

 

[JPinkman]

Will do. The box dossage is 10-20 mls/6" pot. I figure 10 mls should be safe for a gallon?

 

[Imhigh85]

When it comes to fertilizer that sounds like a lot in a gallon of water I'm only using three milliliters and that's one milliliter of cns17 one milliliter of Cal Mag Plus and one milliliter of pro blend tea and I can water everyday with it

I really wouldn't worry as much about nutes and upping them than getting your girls in the right home. Way too small for 4 weeks. All the bat guano and extra nutes if not addressing the actual issue. Get some good soil- doesn't have to be super $$ or fancy but organic is nice. Add perlite 70/30 and they will love you!!!! Then stay with light nutes for a week or two plus cal mag. I don't like premuted soil myself. I prefer to have more control over my nutes but really, good organic soil- I do use work castings but not sure if it makes much a difference.
They are choking in those cups though.. guarantee you have a knot at the bottom of those cups. That leads to either the roots being stuck in stagnet water at feeding or drying out when moisture is low. Low moisture is good if you have good soil but not if they are just sitting there exposed at the bottom of the cup.

Keep us posted and good luck!
