Is this nute burn?

Hi All new grower in the midst of my fist grow. Growing in FFOF. Strain is Northern Lights from nirvana. Day 50V just started using the fox farms nutrients 1/3 of the recommended amount every other watering. My temps are great 65 lights off 75 lights on. Humidity is super low around 30%. This week i started noticing some brown spots and yellowing on the lower leaves. Looks like its become worse and now some higher leaves are getting the brown spots. Any help would be appreciated. Edit: adding a few more details. My tap water PH is around 8 we have a well. The run off ph was about 6.5 when i last checked. THis plant is growing under a 600 watt MH

No, it's not nute burn, it's a calcium deficiency.

What type of water are you using?

Do you have a cal/mag product and how about worth castings?

I'm just using my tap water. Its well water. No cal/mag product just the fox farms trio. Soil is just perlite and ffof no worm castings. Any recommendations?

anyone?

i sencond what crab pot saying you need to start giving light nutes with some cal mag plus, remove old yellow and damaged leaves they not coming back will just cut light from new growth ( get it done )

Cool i the cal mag is on its way from amazon. I've read some places that say dont remove the leaves. Is there any issue if i leave them?

Joejoe gave you good advice...

I don't remove many leaves myself but I would definitely get in there and remove all those yellowed, deficient leaves ASAP. Usually, when growers are talking that they don't remove leaves, the leaves are either healthy or the plant is already in flower. In this case, they are only going to block light from the healthy leaves and bud-sites/buds.

If you can get worm castings, they would make a big improvement and get your plant ready for flower. You would just need to top dress with about a of 1/2" castings. Actually I would mix the castings and FFOF at 50-50 and top with 1" of the mixture.

Thank you guys! I removed the yellow leaves tonight and the cal mag should be on my doorstep when I get home from work tomorrow.
