Veins yellowing, lower growth looks worse

[Eriksan69]

This is something I’ve been fighting a while... ph is at 6.3 in soil, I had a problem with fungus gnats but they’ve cleared up a week ago and new growth is still doing same thing. I give flowers kiss once a week and if I don’t monitor ph it does like to rise to unhealthy levels. LST:73-78F and ambient temp sticks around 73-81. Light is HLG Rspec 600, it’s chillin 30” above canopy at 450W. I’m stumped peeps Strain is kush mints and these are clones. Thank you! (Unsure of my water hardness which I know sucks but I’ve no means of checking that atm)

Magnesium deficiency or nutrient lockout due to ph swings. Do you use a calmag supplement or epsom salts and gypsum?

I have not! But getting ph right was tricky for me, I’m very new so it did swing between extremes a few times.. that would make a lot of sense

flowers kiss is for foliar feeding, are you using it in the soil? you need a veg formula feed..
