Leaves real yellow (pics)

[ZKJ]

Hi i had a bit of yellowing leaves but just fed them water incase was nute burn (on tips) but now after mire nute feeds they have turned all yellow.mainly the bottom leaves. I am not sure what to do.flush soil or keep feeding nutes.i just fed them nutes because it seemed to match up with nitrogen deficiency.and that said feed nutrients.but not sure if i just made it worse.so thought ild post a few pics and see what you guys say.any help appreciated (the first pic was first signs the other pics are todays state)
Just wondering should i not worry that much and also will it stay like that even if problem is sorted or will they go green again.
At first thought was either light burn or nute burn so raised light and fed just water quite abit to sort of flush soil.

Thanks

Problem: mentioned above

Medium/grow method: soil (biobizz allmix)

Feed: and supplements used: biobizz grow/bloom

water source: tap (left to sit out for at least 48 hours/always ph'd to 6.5-6.7)

Strain/age: vision seeds northern lights.not exactly sure as all plants are different age/forgot.trying to go off when plant is ready (trichomes not a time like 8 weeks)

light used: mars hydro 600w led

Climate: 20°c lights off 28-30°c lights on
(Just bought tent heater so will be consistant ttemps when it comes) humidty around 50%

Additional info: think tap water is hard where i am.and always done maximum of half the recommended dose on nutes.

It's common for a few bottom leaves to turn yellow but you have more than average so that could be a sign of nitrogen def.Also looks like a little nute splash on a few leaves but not to bad.I would give her a little higher dose of nitrogen,with added cal/mag 1/2 tsp per gal at every watering.The lower yellow leaves will not come back so just remove them.After you feed them try and spray plain water on any leaves that may have got any nutes on them.

Thank you i will remember the spray thing and will have to get the nitrogen and cal /mag. Also how should i remove leafs cut them? And right by end of leaf or by main stem

Thanks

Just use a scissors or sharp knife and cut them close to the stem.No need to buy nitrogen just use your veg nutes.
