Please help with autoflower white widow

alright guys I need help I have a white widow Autoflower approximately week 7 to 8 flower I use Fox Farm Trio nutrients under a 2000 watt maxsisun LED temperatures have been a little out of whack meaning a little high I believe that I was also having lockout so I flushed now I am seeing this weird yellowing on my fan leaves and I'm not sure what it is please any advice would be great I have also been using Mammoth p and recharge intravenously when not nutrients

Don't shoot up recharge, too chunky.
My GUESS is magnesium, epsom salts. no idea how much to use

If you flushed all the nutrients out of the soil...and then the bottom leaves start to yellow...kinda tells the tale itself.


Feed the plant.

Those do not look like 7-8 weeks in flower. They look like week 3 or so before the swell

Also those burnt tips on the rest of your leaves are indicative of over fertilization. Nutrient burn. Youre probably just about to hit nute lockout. Dial your fertilization strength back

you washed out all the nutes, and nitrogen is usualy the first to be noticed, the plant is taking nitrogen from the lower fan leaves

Potassium deficient

I flushed about 2 weeks ago then I used quarter strength nutrients Fox Farm Trio I've been using recharge and Mammoth p days I'm not giving nutrients I was afraid it was too much light intensity or temperature and I have been feeding my plant full strength nutrient it is week 3 of flower I meant week 7 total

It just really confuses me because the whole Leaf does not turn yellow like nitrogen it leaves the center Green yet the leaf still falls off but yellowing edges and tips turn brown crispy

One more thing when I water I normally use one gallon of water it is in a 3 gallon pot I normally water using the entire gallon when I flushed it seemed like I may have over watered could this be a sign of over-watering

Here is mine 5 weeks today in flower, keep feeding nutes. Your another 5 weeks to go at least. And i am only using 45 watts

It is weird because it's supposed to be a 10-week strain and it is now week 8 week 3 of flower

Yours looks pretty good I got some G13 going to that looks amazing

Plan for plants to finish MUCH longer than the breeder estimates.

I think they meant 10 weeks for flowering

I’d say pick those leaves off and carry on as normal. A whole gallon for a 3 gallon pot seems extreme to me. I use a half gallon per each 5 gallon pot when I water. I always get a little runoff, so I assume that’s enough. I’m less than two weeks from harvest.

How should I use recharge and Mammoth p

Don't know much about pachyderms, but recharge, you just use between feeds or few hrs before a feed. I only use it a every few weeks. I do make sure to use it on seedlings early on though. Makes me feel like I'm helping

I've been using intravenously with my nutrients so I will give nutrients then the next watering I will give pH 6.3 to 6.5 with recharge in Mammoth p it seems like I'm having a nutrient lockout as my leaves are turning worse by the hour
