Indoor Yellowing spotty leaves

[Think]

These are not my plants, I'm in week 6 but mine have the same sort of problem but only one of them are really bad. There is a lot of yellowing (which auto's are known for) but it's like the leaves or spotted with yellow and the tips are yellow and dry??

I'm following Tang's Feeding guide and I am using cal/mag what gives?? if someone can help that would be great cheers!

Rust Spots Are Magnesium Deficient
Yellowing like that is looking like Calcium and could be Nitrogen...

I say Boost your feed maybe
Also just because you feeding AN doesnt mean the soil is Ok
Which Brand Soil/ Medium Did U Choose

I thought rust spots was calcium and yellowing was magnesium.

Just because you use the PH perfect from Advanced, doesnt mean it will be perfect!! I use Advanced Sensi A&B grow and bloom and still check my ph. In fact, I am having problem on my current grow with the ph being to low in my oil. I am feeding 6.3 and my soil is lower, but in the 6 range and getting a touch of lockout. You really need to check your PH in and out!! to see where your sol is at.

I am using BioBizz and have been told the PH can be low in the soil so maybe thats it..

Hmm that's true! I am using BioBizz light mix which can be a bit low on the PH so maybe that's it!

Hi man i just saw some wrong information and had to chime in so i hope you dont mind. Sorry now but i have to make a correction. rust spots are a calcium deff and yellowing off with the Leaf vein staying dark is a magnesium deff. Hope you get it sorted man.
