My leaves are starting to get yellow!

One of my plants is starting to have this problem and i cant find out what it is!

Nobody knows what it is :/?

First off, are you feeding them anything? What is that medium I see there?

Because they need to be fed, or you need to water less...if you overwater seedlings then they will start to look washed out...but they might just be hungry...

Well I answered my own questions...you either are feeding them, or overwatering, because I see that your leaf tips are a tiny bit burnt..so space your watering more...as in let the pot get totally utterly feather light and then water with whatever nutes you want to give in a small dose...then allow the pot to dry again...as the plant gets larger they need watered more frequently, but the plants will grow way faster if you wait for the pots to get super super light before you water...

Also what's the ph of the soil?

Well i fed them 3 days ago and it first started to appear alittle bit yesterday and today it just seems to be getting worse :/. I don´t know what my PH since i don't have a meter,

Ph is your problem. The plant can't absorb the nutrients, your ph should be about 6.0-6.7. Just go buy ph test drops from hydro or pet store and test the run off water from soil when feeding.

Possible light bleaching/heat stress. How close to the light are they and temps?

Isnt there anything i can do without getting a ph meter? because its still getting worse :/ also the lamp is aleast 3-4 inches away

Like I said go to the hydro or pet store and buy ph tester drops it's cheap.

Leaves also taco-ing so prob high temp & low RH as well as overwatering or PH lockout. If the soil is too wet then the drowning roots can't absorb the nutes.

Please get urself a PH meter and start the feed at 1/4 strength every other watering. Waits for pots to lighten up.

Picture of the whole plant would be good.

Don't do that.Yes it's good to know the ph, but don't test the run off from the pot.What ever your soil ph is, that is what it will stay.

I grow at a 7ph
