So I have 2 autoflower plants in the last few weeks of flower and 1 auto just starting flower. They are all in soil (mix 10% ocean forest, %40 Happy frog and %50 Aurora 717), 4x4 tent, Spectum king 402, 20/4, AC Infiniti exaust fan, 2 clip fans, 3g air pots & fabric pot. Temps 82°-72°, water when needed maybe twice a week. Have been doing Technaflora nutrient success box or whatever since about a month old, Did a flush a week ago because they weren't doing well, runoff ppm 625 and PH was 5.5 when I was putting 6.5 in, so I flushed until ph was 6.3 and ppm around 300. I've given bloom nutes thinking it's a phosphorus deficiency but then they looked nutrient burned with leaf tips browning, now they have stopped putting on weight/stacking buds and the leaves yellowing, spotted and most have red/purple veins even the green ones. What is going on!!? Thanks in advanced!!!

When I use ocean forest or happy frog I give no nutes during first 4 or 5 weeks of veg. Then veg nutes till i flip to flower. I use 7 gal pots tho.

So you have flipped to flower, but the plant still needs a little bloom nutes maybe low N.

Also could be calcium or magnesium deficient if you ain't been hitting it with cal mag suppliment.

Add cal mag and watch ph would be what I'd do.

Some smart plant guys on here might tell you different thi.

Yea I gave bloom nutes 2-11-8, and then they showed nute burn so I flushed a little bit not fully, like I said until ppm was around 300 so they still have nutes in the soil left to use up, then the yellowing, brown spot shit showed up. Idk man I cant figure it out
 
Yea it was in the nute regimen, I haven't given anything since the flush last week after the nute burn. Maybe I'll do a cal mag foliar feed see if it helps
 
These are the 2 closer to harvest with the burnt tips, yellowing and red stems with some necrosis spots

Basically I think you have a few issues ... definitely N and P deficiencies... but im guessing thats lockout related since you clearly had low root zone pH since it was dropping so much during watering... probably from salt buildups... not real familiar with Technaflora though so hard to say...

Was thinking leaf septoria but it just doesn't look right... dunno. Definitely remove anything with necrosis from the tent and make sure your root zone pH is under control... Your not gonna see any improvements in the already yellow leaves, your just looking for healthy new growth and foe the leaves to perk up

I'm not seeing the calmag issues others are but ... shrug?
 
Thanks guys, I just made a gallon with aggressive parts Cal mag and sugar daddy which is magnesium and sulfur, and some awesome blossom which is 2-11-8, I have it aerating now with the air stone so well see how it goes. The root ph zone has leveled since the partial flush so hopefully these girls can uptake all this good stuff I'm about to give them.

You really think it's a N issue this late into flower?

Its not that late. Breeder pack may say so but those buds aren't halfway yet. Maybe just about. You're at least 2 weeks of N behind.

I see PH issue all around. PH swung too far both ways maybe? Not sure.

You said they were starting flower?! FWIW, Best to keep them green right up to harvest and any seasoned grower will tell you the same.

Yeah except we move forward and learn with time. The A.C.E.(autumn color effect) aka The Fade produces superior cannabis. Anybody who stays up to date with science and technology, will tell you the same.

That is why Cookies hits the shelves 3 weeks after harvest. No waiting for nasty ass grass flavor and smell to disappear.
