Marijuana plant looking sick right before/after flowering full pics

Hello Guys new grower here.

I have this auto flowering auto berry plant
Should be around 1-2 week of flowering
250w hps light
Soil with hesi nutes
Temp Usually around 28c
Humidity usually around 50%

After and a little before flowering my plant looked a little more pale, some spots on the plant as well, some tiny brown spot.
Doesn't look like I have any bugs or fests.

Wondering if this is normal? Do this look like they are lacking any nutes? Am i doing something wrong?

Would love to hear your thoughts!

Hi....how often are u giving them a drink?

Usually every 3-4 days when the top soil is dry.
Usually around 15% nutes on "clean days" using purified water
Or around 30% with purified water ( ph around 6.5 )

They look hungry for a little N

Checked all options and decided to take them out of their pot.
Looks like they totally growned out their 3 gallon pot!
They are only ALMOST 1 month old ( from SEED! ).
Cutted an other 3 gallon pot bottom until I'll buy a 5 gal pot to replace it.
Adding almost an extra gallon for the meantime.
Crazy, but was this the right move?

I think they were just needing nutrients added. I grow much larger flowers than that in 3 gallon pots.

In a couple of weeks you will likely have the same thing happen. Be prepared to fertilize if you want big healthy buds.
