Light bleaching or nutrients issue?

Noticed that the bud closest to the light (led sf2000) was starting to turn a lighter color, so I raised the light up.
I thought it helped but now there are purplish blotches on some leaves as well.
In 4 gal fabric pots, fed with FF big bloom half strength every other watering.
It's only has happened to this plant and branch.

What's the strain?
All you feed them is FF big bloom (0 - 0.5 - 0.7) nothing else? If so it may be to the point it needs more
Yes, started giving them that couple weeks after flip. The soil is 30% Pro mix 4(peat with amendments) 30% FF Ocean and 30% Recipe 420
I was feeding them FF veg and kelp extract in veg.
The strain is Hindu Alien (alien dawg x afghan)

Alpha hit it on head. Big Bloom isn’t a “ blooming amendment “ it is a micronutrient source for the medium ( soil ).

You need to give it a full bloom nutrient ( tiger bloom or other )…. Plant is starving. Plant is cannibalizing itself ( fading leaf / lack of nitrogen / pigmentation ).

Got it!
I'll pick some up today.
Thanks

If you are in soil - home depot sells Dr. Earth Flower Girl dry fertilizer. It is an option for you. A literal tablespoon or so scratched into top soil
Sounds good. The more I read I feel like I'm going to go this route for future grows.
Less bottled nutes more scratched in organic dry fertilizer and top dressing. Really want to try and reuse soil, I can see it becoming quite expensive.

Update
Picked up the Tiger Bloom the next day and gave it a half dose. Seemed to help a little, at least slowed it down it seems. As you see it is still slowly fading.
My questions are, will the leaves ever turn back green, should I increase the amount of TB and also should I be worried about those yellow sugar leaves that have now been engulfed by bud, rotting and starting mold?
Thank you everyone

Tiger Bloom allone doesnt have enough Nitrogen. Its totally wrong to lower Nitrogen in flowering.

In flowering the plant needs a small amout more of everything up until the last 2 weeks before chop.

IMHO and from what Ive read from places doing tissue samples, a 1-1-2 ratio is optimum.

I use Master Blend 4-18-38...15.5-0-0 Calcium Nitrate, and Epsom Salts. I much prefer getting my Nitrogen/Calcium, and Magnesium/Sulfur from Calcium Nitrate, than Epsom Salts, than any other sources, unless Im doing organic.

But regardless of nutrient source, balance is key, and you basically need as much Nitrogen, as you do Phosphorus.

Also if you notice Fox Farm blends both Tiger Bloom, and Grow Big in flowering. Tiger Bloom alone isnt enough nitrogen

I also dont believe in changing from aveg formula, to a bloom formula. Just give them a balanced feed from seedling-flowering. And all that other stuff they, and many others add in is just a money grab, and makes it way more complicated than need be.

If I was doing organic, and wanted to reuse soil. Living Soil is the way to go. Ive also used Peruvian Seabird Guano, both high nitrogen, and phosphorus formulas. Calcitic and Dolomite Lime in a 2/3 calcitic to 1/3 dolomite ratio. Kelp, Azomite, Bioactivator. A small amount of 0-0-52 Potassium Sulfate.. But Living Soil is much easier to reuse.

Thanks for all the useful info.
This first indoor run has only a few more weeks to go. But I will definitely use this chart for future grows. I'm reading up on Living soil.

Ive seen this before a few times and no, you wont get green leaves again. Imho this is light burn in flower, it kinda looks like the leaves go into senescence. It will still harvest and yield ok

I think you might be right. The leaves haven't died, they are just yellow now.
