4 weeks old - Mg or Ca def?

[Timboy5]

I've been giving them 100ppm of Magical adding Liquid Karma until 200ppm then adding Pure Blend Pro until 400ppm.

This happened within the last 24 hours on plants that were transplanted.

I had them in keg cups which I know now are too small for plants. In the future I will be running 1/2 gallon starters.

Here is a picture of my healthy ones. Looking like they need a little stronger mix of nutes but I am so afraid of over fertilizing them

pH has always been @ 5.8 run off is 6.4 not sure how much that matters.

I am trying my best and it is frustrating to not have them grow right.

Another pic of all the transplanted / sick ones.

Don't look to bad lower leaves will yellow... Ur new growth looks good that's what's important.." I wouldn't worry if I were u and def won't want to up the feed yet... Just lettem go if the yellow gets worse and starts goin up the plant its time to make a stronger mix

 

[Timboy5]

Wow thank you for the fast reply.

I am running 0.5 scale too so 400ppms in my opinion is plenty for them. I will not up it.


Thanks again for the advice.

It looks to me that you are using soil. If you are you are watering at the wrong pH levels. You should be pHing your water and solution to 6.4-6.8. You are having pH problems. You are giving the right amount of PPM. Don't listen to the guy above me. Your leaves are not suppose to turn yellow in VEG.

The blend is primarily coco so I have been using a 5.8 ph

Well if that's the case then your run-off is in line but your feed is slightly low for coco going in. It works out though because your feed is fixed in the run-off.

FFLW is soil and you state that you are using 60% soil. FFLW out of the bag is 6.4 - 6.5. So it is normal that you put in a pH of 5.8 and it comes out higher. Eventually it will come out lower and then you will start to see more problems. It is confusing that 60% of your medium is soil and 40% is coco because soil is supposed to be at a higher pH than coco but coco is still supposed to be at least 6.0 if not higher. The pH of your run off is where I would want to be and I would be nuting at 6.4 as well. I still believe that your problems stem from your feed solution being too low.

I agree I added the coco because I've used it before and found it to be too light of a mix.

So my next watering will be 6.4 ph. Should I stay at the 400ppm?

100ppm magical
300ppm pure blend pro

and just skip out on the Liquid Karma

I didn't realize FFLW was soil I assumed it was coco or ignorantly assumed it did not matter.

Just come back from the hydro store. I planned on doing these in hydroton w/ ebb n flow tables but based on the problems I am having I purchased some Ocean Forest instead and will be running these in soil.

Thanks for the help you saved me a lot of trouble.

50/50 mix FF / LW - #1 pots
Ph in 6.4
PPM in 100ppm from tap then 1ml/gal Roots Excel and 12ml per gal rhizotonic ending ppm was 150.

ph out was 6.8
ppm out was 700-800

Wish me luck

Nice I like FFOF! I nute my FFOF at 6.8. I like the run off to be at 6.4 though. It comes 6.4 out the bag in my experience. FFOF has plenty of nutes in it already. You don't need to add any feed for about 2-3 weeks depending on pot size. Just add water.
