Leaves can't figure it out (noob)

[Choksondik]

Hello, little description of what am I doing: strain is autoflower dieselryder she is 33 days old, its in 3 gallon pot under 400w hps. Soil is Biobizz Light Mix.
I didn't use any nuts until I saw (last week) that bottom leaves are turning yellow. I added little nirvana bloom and some sensi grow part a 3-0-0 part b 1-2-4 but it didn't help. Its like spreading to whole plant.

Is this calmag? Can't tell from other pictures I found on this forum and other sites.
Ooh and water is tap around 6-7pH(still waiting for pH meter I ordered from china for more accurate measuring).

TY!!

How much are you watering, how often? What kind of soil? Lights? Temps?

I'm leaning towards over watering.

 

[Choksondik]

I did mention soil is Biobizz Light Mix mixed with 30% perlite and light is 400w HPS. Temps are 27-29c/80-84f. I test soil with finger about 3cm/1.2inch in. If its dry I water around 1L per pot.

 

[whitebb2727]

You did mention. It looks like a combo of over water and it is hungry. Give it some more grow. It needs some N.

 

[Choksondik]

Ok. So should I add calmag also? From pictures above looks like N but then again it looks also like Mg and Zn....

You need to get your pH in check. "tap around 6-7" is about a 15/20% deviation. The slight yellowing was because she was hungry and by the sounds of it she was due to be hungry. If you watered with tap at 6 pH the nutes pulled it down to low 5's maybe even sub 5 causing lockout. Get her fed with properly pH'ed food. Furthermore, don't look for dead leaves and spots to recover much if at all.

Also, when you say you added "a little" nutes, how many PPMs was that? Until recently I did old school pinch here, a touch there...maybe a little shot of this a smidgen of that...It makes for a stressing grow for both of us. Now that I have a $35 PPM meter and feed to collective recommended dosages, I am learning just how heavy handed I've been with nutes over the years. Look into a TDS meter along with that pH meter. Good look my friend.

411PPM with nutes. Can't check pH atm .

 

[Choksondik]

So its not getting any better. I check pH with test strip its around 6-7pH after nutes and 409ppm. I didn't add calmag yet.
