Yellowing leaves

So this is my folirst grow on day 25 of flower and getting some slight yellowing to my leaves..just curious if this is normal or I have a problem? 4x4 tent vs4000 light lights on temp avg 82 lights off 72 6inch exhaust fan running 24/7 and oscillating tower fan also running constantly...I'll post some pics after work

Well you’ll get more accurate responses after work. Whole plant pictures please.

Also some info on nutes, watering amount/frequency would help

They are getting tap water set out for 3-4 days prior to watering ph 6.4 to 6.6 temp a good 72-74 feed then water twice before feeding again. They are getting about 2 litres every 3-4 days

Container size? There’s no need and no benefit in leaving tap water out like that.

5 gall9n fabric pots...and doesn't tap water have to sit out to let the chlorine evaporate?

“Yellowing” is a very subjective term round here.

Pictures are needed….sometimes yellowing is just normal and sometimes the answer is you should asked for help a month ago lol

In full veg. a 5 gallon should be 1 gallon of water/feed every 2 to 3 days. You should also be feed water feed water. Your starving the plant of food when you water twice before feeding.

OK thanks for the info my amount of water seems to be enough I use a pump sprayer to wet the tops of the pots then wait 10-15 min to water slowly until I get some runoff

This was my girls on 5-28 very little if any yellowing except for plant in back right corner, it was overwatered when young and never fully recovered

How much food? What kind? Just bloom or grow?

Using gh flora series trio and feeding amount according to their chart

Did you stop all nitrogen in your feed? It looks somewhat starved for some (not a lot) of nitrogen in flower but you never want to go nitrogen free till towards the end. That maybe due to feed water water. Rotate feed water.

No didn't completely cut nitrogen out still getting like 1.5 or 2 ml of flora grow with each feeding

I wonder if they say to use just bloom now? What is the bloom NPK ratio?

As 420 said you want a little more N in your mix. You can always cut grow and bloom together to custom feed your plant! So want more N some want less, yours wants more. Go 25% grow 75% bloom

Ah… what are the NPK ratios of the grow and bloom? Maybe needs a little more?

How many ml of bloom? I dare say you just need more grow. I’d try 2.5ml.

But tbh the colour is still great, just don’t want it to fade too soon at this stage!!
