Nutrient deficiency? Advice needed

[Spongebob420]

Sup guys, on my first grow atm and Iv ran into my 1st problem. From all the pics I've seen and info ive read I'm pretty sure its a calcium def. There's brown spots appeared on older leaves and theyre pretty theyre sides have turned under. Am I right in saying this is a cal def? The plant is a narcotic kush on day 13. Iv not started feeding yet signs of def appeared over the night. My ph has been the same from the start, 6.5 overall the new growth is looking good. Any help will be greatly appreciated.:smoking:

What soil is she in Spongebob..?

 

[Spongebob420]

Hey duggy, Bio bizz light mix soil

 

[Duggy]

I'm on a phone so not great for viewing pics. pH not usually an issue at this stage in lightmix. When I ran lightmix I was giving foliar feeds at this stage.
Do you have nutes..what size pot..?

Sup man, I have tomatoe food there I which I was going to use for vege, waiting on bio bizz nute try pack coming, was ordered a couple of days ago. The npk ratios on the tomatoe food are the same as the bio bizz grow. My pots are 11ltr. Thanks for the help

I'd make a feed at 20% strength and give the pot a good wetting once the biobizz arrives. What are you using for pH measurement?

Looks like she needs some feed to me. Give her 1/4 strength of the tomato feed with an extra 1 ml/L of CaMg supplement. How's your humidty in the grow space?

At day 13, it's too early for calcium def, Spongebob. Could be a number of things. Post a picture taken in natural light, otherwise we're guessing.

How are you measuring the pH?
