Flowering nute feeding

Hi guys

Plants starting to pack some weight now. Just trying to figure out the feeding on this one. I’ve been following the nutrient instructions (but giving only half the dosage)

I have noticed tips turning brown but at the same time bottom leaves are kind of yellowish.

Im struggling to identify what nute should I reduce and what should I increase to have them balanced. I know the tips won’t recover but want to give them the best feed possible

Can anyone help me out on what sort of deficiency are they facing?

Info for the grow are

Growing wicked monkey Auto flower (plant 1) dream berry auto (plant 2)
Coco coir with 30% perlite
50-60% RH
1000w viraspectra LED
5.8 PH

1.2x1.2x2 grow tent
6” exhaust fan (off most days)
1 little fan

@Purosuco. Looks like they’re getting hungry for p and k
When they start forming buds the requirement for potassium and phosphorous goes up.
If you could bump those it will help with the yellowing leaf and purpling stems.


@Oldguy and how about the burnt tips?

Should I worry about it?

@Purosuco. Not really. Just keep an eye on them after bumping the feed.
They won’t green up but should stop progressing any further.
