Yellow leaves

[summerigrewup]

So im 4 weeks into flower. My babies have yellowing on the fans and colas. Called the hydro store they said I need cal-mag. I also believe I need to get some bloom as well. Yes, no? Ideas? They are in ffof. I tried epsom salt. Worked a little. Advice please.

hydro store is probably correct, yellowing of the leaves = calcium/magnesium deficiencies, OR your PH is wrong and its not taking up the Ca/Mg in your water...pics and stats to better determine

It take so long to upload pics from my phone but im pretty sure thats what it is

I'd just do a once over of your PH to make sure you are at a nice 5.6ish...I am making the assumption you are growing hydro of some sort since you called the hydro store

If you are doing soil, you want a PH of 6.5.

Be sure its not your PH causing lockout

I dont have a way to check my ph at the moment im broke but I can prolly get some cal,mag for now

 

[skunkushybrid01]

are you feeding NPK?

it is more likely to be nitrogen than cal/mag.

It doesn't matter if you get the cal/mag if your ph is what the problem is you can add all you want. Get a simple ph test kit and start from there.

not likely to be a pH issue.

he's in soil, pH issues in soil are rare... he has no money... the plants need food. i'd bet a simple feed from an all in one nutrient would fix his plants right up.

If a ph meter is cheap I can get it too. Wasnt sure how much it was. But I do have some ph up and down?

 

[skunkushybrid01]

spend your money in the right place... your soil will naturally buffer to 7.

all you need to do is feed them.

would you be so anal over any other plant? i bet you'd just use tap water and watch them thrive. cannabis is a big plant that needs food. buy some food. a pH pen isn't a priority.

Right people that think growing weed is easy, has obviously never tried. Kk im going to get some nutes and i also ordered a 250 watt hps that im gonna put them on when I get the nutes. Currently under 150.

ph issues are far from "rare"

i've grown in soil without any pH adjustment whatsoever lots of times and never seen an issue. at forums like this though it happens all the time as people try to explain away what seems to be almost every problem as being pH. Misdiagnosis is the cause of that... nothing more.
