I opened up my tent today and saw that my leafs are turning a bit lime colored and some with brown spots is that some sort of deficiency?....I'm growing them with Fox Farm soil...Using the general hydroponics trio set currently at the aggressive veg regiments along with Cal Mag silica rapid start nitrogen algen extract I PhD it down to 5.8 the temp in my grow room is 74 degrees and humidity is at 45% with 3. Fans running top on top and one on foot lol with a mars hydro 2000 watt quantum led at 75 percent capacity...what could it be and how can I fix it ....please help?
Whats that on my leafs?

How close is your light ? Your temps and humidity are low. It looks like it may be a combination of things negatively affecting them. One could be light stress and the others are definitely low temps and humidity. Did you feed because your soil ran out of juice or did you just start feeding just because? What ppm/tds is the solution you are feeding at ?
I drained it all out to avoid root rot and checked it and the Ph was 6.1-6.2 roughly
What do you suggest...I fed it today cause it was feeling light...i gave it some compost tea at 6.5 ph and ppm if under 1000....the runoff came at about 6.1 to 6.2....should I cut those damaged leafs?

If it felt light then it likely needed to be watered. Watering and feeding are two separate things. I was asking if you started a water soluble nutrient regimen because you noticed deficiencies as a result of the soil running out of nutrients or just because? Also you didn't answer my question about the distance of the light. I see in the last picture that it seems to be pretty high up. Was it always that high up? Did you increase the intensity recently?
Should I cut off the leafs that are dying out to avoid wasting energy and nutrients to them?

I would focus on fixing the problems first instead of cutting and possibly stressing the plant even more. Try lowering the intensity of the light even more to see if the symptoms subside. I recommend lowering down to 25%. To me it looks like light stress more than anything but equally important is that you fix your low humidity and low ambient temperature. Your leaf temps have to be low since your ambient temperature is 74. Those 2 combine equate to low transpiration rates.
Here's how they looked this morning....I turned down the light to 25% and turned on the humidifier

First glance that looks like unhappy roots.
Either too cold or too wet.
Put your thermometer at pot level to take a reading.
Not seeing any leaves that should be trimmed.
What’s your light schedule?

I got it on 24 hours but bout to switch it to 18 6

My leaves did the same thing. I turned down the light and it kinda helped. So I raised the light. That fixed it (but it took a couple days to effect). I even turned the light back up after raising it.
I was using the TSW2000 (really only 300W).

Light stress can look that way but usually affects the tops mostly.
Yours looks more systemic as all the leaves are affected.
Unless you had the lights just totally slammed down on the pots.
I’d still check the temp down at root level, and also try the recommendations that seemed to work for the others.
Also, when you say “felt dry”, the pot should be ultra light. Surprisingly light.
A small root system in a large pot cannot handle saturated soil.
Good luck.
I'm thinking it was the fact that I added half a millileter of nitrogen to my nutrient mix to up the growth that it was a bit excessive...my lights for a good min were down lower but I saw the leafs change after my last nutrient mix....I usually feed 3 times a week water nutrients and compost tea...
I raised my light and fed it some compost tea sunday....Wednesday is its next feeding considering the pots light
By any chance could it be a nitrogen deficiency or toxicity?

Deficiency...because your pH is too low
