They're 2.5 weeks old... FFHF should be good for a month unless you're growing something vigorous. GH is ok (I love it, in fact) but go easy... Like @RGWD0202 said, 1/4 strength and go from there.

I gave them 600 ppm, thinking the browning might be due to a lack of nutrients. I should have done more research before adding the nutrients, as I may have burned them on top of the original issue. The other plants are doing much better than this one, but they are also starting to brown at the tips. I'm not sure what the problem is. Do you think I should add Cal-Mag, or should I just water them and wait it out?"

I would think of the soil is getting close to being depleted then CalMg would be fine, but start with a light solution. Can also foliar feed, but usual precautions apply.

If it's starting on the tips you're burning them, not a deficiency. Chill with the feeding for a bit.

Way more plants get killed by love than by neglect! Less is definitely more sometimes!

Good catch! I didn't, um, catch that part.

And you're learning a lot, under stress... Zoom out and breathe. Make notes, and keep moving forward.

It started before giving in nutrients just gave the nutrients 2 days ago

You mentioned earlier that you pH'd your water ... What's your water source? What is your water source's pH and EC?

Hello, it would also be advisable to have a pH lower than 5.5 or 6 because these minerals are the first to stop being absorbed when the pH is high. The irrigation ph is always better at 6.0, no more.

Been watering with 6.4 -6.7 ph tap water left out overnight with a bubbler in it to declorinate the water

I've been watering with tap water that has a pH of 6.4-6.7, which I leave out overnight with a bubbler to dechlorinate it. Not sure what ec is to be honest or how to check it

How would I go about keeping the soil pH around 5.5 to 6 would I just water with a lower pH like 6.2 or 6.0?

Tap water has a much higher pH for human consumption. It is not a good option, you have to lower it with a lower ph acid or lime juice or vinegar until you get that value 6.0, only with that it will improve everything.

Yes I have been adjusting my water to around 6.5 pH before every watering my water out of the tap is 8.1 ph

Soil pH is also 5.9 - 6.0

So your water straight from the tap is...

My bad I miss read you post about the water pH before any adjustments the ph is 8.1 to 8.2 the ppm is around 200

Your water doesn't need any cal/mag from those numbers imo. It's way alkaline so you're doing great lowering the pH but that 200 ppm is likely the result of calcium carbonate already in the water. Chill with the calmag for now until you actually see a calcium deficiency.

Better 6.0 or 5.5 to water always at ph 6.3 or 6.5 the soil is raising the ph. It is also good a good watering with mineral water of bottle.

I'm confused lol if it's not cal Deficiency. then what could it be may have some nutrient burn from the early feeding but the browing started before the 600 ppm feeding and after is when the tips curled up

Last week, I noticed some spots appearing on my autoflower at 2.5 weeks old. Initially, I thought it might be a nutrient deficiency, so I added 600 ppm of nutrients. However, three days later, the condition seems to be worsening. I’ve been watering with pH-adjusted water, keeping it between 6.4 and 6.7. I also have two other plants in the same area, and they only show symptoms on the tips of the leaves on some of the lower branches.

I am seeing same on some of mine but only on the leaves facing the lights ,I wonder if they are to close

Pre mixed amended soils like FF are frequently to "hot" for young plants already, especially if they're watered a little too much. Like I said in my original post, it looks like a pH fluctuation issue, not calcium.
