Help 1st time grow 3 1/2 week into flower

Anyone help my leaves are starting to yellow. I increased my bonicare bloom last week. Leaves look like there yellowing, I topped my plants with ffof a good three inches. Here’s some pictures.

how’s this look??

You need a bunch more phos and pat. Probably some cal/mag too. Should darken up after. Add it in slowly day by day. What are your ppms at?

When I test the water ph it’s 6.2 -6.5 but soil ph is more like 5.2 when I put the wand in the pot.

Need to get that way up. Roots need soil between 6-7 ph. Plant is not up taking nutrients because it's so low. Ppms is different though, but now that you mentioned the ph, that should be your main concern.

Do people feel veg nutrients e.g. nitrogen during bloom like 50/50 veg bloom? Im debating adding a less than 50% dose of nitrogen

Plant doesn't need much nitrogen during bloom. I would suggest doing some research on nutrients and when / how much to feed of each.

I looked at some feed schedules actually have 1/3 of the Nitrogen that is given during veg for the 1st three weeks. I haven't been doing that, I wouldn't have assumed top off was enough
