SOIL pale brownish spots on leaves

Hi everyone,

I've been seeing these weird pale brownish spots on the lower leaves of my plant, there also drooping. does anybody have any idea what could be causing this?
I'm using a qb280 as my lightsource. the temperature has been steady at 23°C for the past week with humidity around 65%. they are in their fourth week now.
as feed i'm just using these organic tablets, that i've been using without a problem for the past couple of grows.
 
it's just organic.
It's this local brand a lot of people in the netherlands use, and i've never had any problems with it...
also only 2 of the 3 plants seem to be having a problem.
thanks for the reply's so far by the way
 
i've thought about that, but it seems weird that it's only affecting the lower parts.
I just ordered a ph meter, seems reasonable to check out that route.
 
If it’s not an living soil. You still need to monitor the ph even if you are using organic nutes.
Every plant is different, even the soil on every pot with the PH. And the buffer zone in the soil is also different.
Many people are lucky it all fits together. I had some grows where is all where good.
My suggestion is check the Ph in water and soil first.
 
It’s a good start to lockout that question- because a ph that is out of range it can‘t absorb the required nutrients, is actually pretty common with symptoms. And the first starter to problems.
 
I don’t think you have dificiencies. Because you write you are givinf nutes. When I read a little further on symptoms - phosphorus give that kind of marks if it’s missing it. But if the PH is wrong it can’t absorb the nutrients in the soil because of a lockout
 
I don’t think so, to be honest. I water with cal-mag in every water feeding. You live in Holland ? If the PH is on top - then I would maybe look at the cal-mag
 
Im usinor General hydroponics. But all my other stuff is CANNA and so next time I’ll be buying CANNA’s cal mag. But my plants are doing pretty well with GH.

I live I Portugal and are using my tap water, straight. As long as the Ph fits, you are going to be fine 👍🏻
