help a brother out!

hello everyone my plant had a a change in color around the tips of the bottom leaf. it was fine yesterday. its 16 days old, i give it about 1 cup of water/nute mix a day. theyre on a soil mix from local garden store. the edges started becoming soft and yellow and droopy. thanks.

One should feed nutrients in the germination stage and start feeding at reduced rates in the seedling stage. one should be more concerned with "root" development in the first 1-3 weeks of development - use a good root stimulator (Great White, ect). You could have the start of "overfeeding" your plants - consider flushing for 5 days - then start to feed again. Good eye !!!!!! Nutrients used?

Honestly it could be a lot of things. But I would say its a combo between overwatering and nute burn.
On a plant that size I wouldnt even be using nutes personally. Amd really wait for that soil to feel light when u pick up the pot.

thanks . I used some local french nutes from Platinum Nutrients. today the same leaves are a bit worse the yellow keeps advancing, ive stopped watering and feeding entirely until the top soil is dry and feeding it water. but i also noticed black gnats flying around in my growbox, are these fungus if so what can i do about it?

If they are really small and black/grwy then I would say fungus gnats. Another sign of over watering. Your pot should feel light when you pick it up if it needs water.
Looking At dryness at the top of the pot isnt a good indicator.

Thanks bro, it's day four since the yellow tips and now my 3 set of fan leaves have yellow droopy tips. I haven't watered thinking it might be overwatering and no nutes cus it might be nute burn. Still see a few bugs flying around. Does it look more like nute burn or fungus ? advise?

Burn

Ya I agree she looks burned.
In most cases that ive seen firsthand (not only in cannabis) fungus gnats dont really do too much damage. Your going to have more damage caused by the thw soil being soaked enough for the gnats to thrive.

The laevae do feed on roots but they prefer to eat rotting organic material. That said if your roots are dying from jot having enough o2 cause of overwater then the larvae will be all about eating those dying roots.

Any advise on what a can or should do?

TBH I would treat as a combination of both. Cut down on the food and water and treat for the gnats as well.
Either way, you are not really 'adding' anything to the soil, just giving it a rest.
It should pick up as it doesn't look as bad as some others I have seen..

btw. I've found that most of my gnat problems came from buying soil from outside suppliers, so I tend to divide it up into smaller bags and put one in the deep freezer for at least a week. It kills all the flies and their maggots. I repeat it until all the soil is treated, then seal it up good for my next grow. Just my own method.
Best of luck.

Good tip. Will try it on my next plant ...cheers
