Same Discoloring Every Time I Hit Early Flowering

[OrionTheHunter]

The details: White widow auto in 5 gallon bucket of Happy Frog Soil, 24 hour LED, temperature is 77 constantly, have soil pH of 6.5.

My past three grows, every time I hit early flowering phase my leaves at the bottom start turning yellow from the base and this then slowly creeps up the plant. Is this as simple as nitrogen deficiency? I was of the opinion that N deficiency started at the tips but this starts at the base of the leaf.

I attached some pictures and would love some guidance-I’ve checked the guides here and elsewhere and can’t tell if it’s Nitrogen deficiency, lack of magnesium or what.

Have you fed them anything yet?

Seems like @n adjustment to environment. Bet it recedes quickly.

Keep your nitrogen up and use epsom salt when you flip I use it every third watering in flower it helps with flower production and nutrient uptake the yellowing is probably from lack of nitrogen and the crispy look is the mag the Epsom salt should clear that up

Nitrogen is mobile, maintaining N to the growing tip at the cost up to dropping lower leaves

Some occasional Tiger Bloom every other watering since flowering started a week ago. Nothing else.

That's not much nitrogen, which is what they appear to be having issues with. They use a lot of nitrogen in early flower, there's a lot of new growth happening at that time.

You may want to consider using something like this the next couple feedings to help green them back up: https://www.homedepot.com/p/Alaska-32-oz-1-qt-Liquid-Fish-Emulsion-Fertilizer-5-1-1-100099247/100131259

Thanks. I have some 6 4 4 grow big from Fox Farms, think that’ll work? Can grab some fish stuff but obviously prefer to use what i have first

Sure, that'd work. Lots of people use the veg/grow nutes for the first couple weeks of flower and then gradually transition to bloom nutes. There is a lot of vegetative growth still happening during the stretch
