Yellow/brown leaves and drooping

Hi, this is my first grow at 4th week of veg growing Nirvana Pure Power Plant and i ran in to some problems at second week with the ph being too high. I think i fixed it after a transplant and i've been checking the runoff ph and it's at about 7 or less. Using the ghe drop tester.

The plants have always been a bit a droopy and now the leaves are turning yellowish/brown at the tips. Some say i'm overwatering, but i usually try if the soil is dry at 2 inches deep before watering. Could be that the bottom is still wet though dunno.

-Temps: 80f

-Soil: A finnish brand recommended by some growers with 30% leca

-Nutes: bio bizz alg-a-mic and bio-grow. I gave them bio grow 2ml per 1,5l at 3rd week, but was afraid to give them more because of the problems.

Here's some pics:

Plant on the left is topped and the other one fimmed.

What do you think guys?

Yeah I've been noticing this with my baby as well I'm pretty sure its just a nute thing or like guy above me possibly over watering

Bump, new leaves got some brown spots too

im a total amatuer , but it looks to me like they have been overwatered (saggy) and that they have nute burn.
Flush them with just water. If you think they can handel it , put them in a bigger pot.
Let them dry out , and reduce the nutes ( maybe try half the recomended dose ) and then wait for them to recover.
