What does this look like, expert opinion please, 2nd week flowering

I am going not my 2nd week flowering and these brown spots have appeared.

A little background info, my plants have struggled with nute burn for a few weeks and starting to get much better but now these brown spots and yellowing has appeared. What would you do to remedy the situation?

I usually water when the soil is light and due to the chemical burn have not given nutes for about 2-3 weeks but slowly starting that back, also the whole time I added water only it showed signs of nute burn still IE yellow tips

looks like it need mag.. look at my journal and look at my girl 2 weeks into flower and i got the same.. give them a lil mag with a sligh normal BLOOM feeding meaning more p-k and a lil n.. good luck.

this is a calcium def like ^^^^ said you need to buy some cal/mag or magne cal+ and add it on your next feeding

i have come to realize the epsom salts are almost mandatory when starting flower. the deficiencies show up around week 2 or 3 usually.

epsom salts are 100% magnesium so wouldnt cure a calcium def where as magne cal+ or cal/mag isnt they are your best option

Thanks for the responses guys! I will put that into work!

Yup- that is a cal-mag deficiency- not nute burn... Give them a shot of Super Cal-Mag or Earth Juice Micro-blast etc.... right away!
