Week 7 of flowering and need help!

Hey all, first grow and in the home stretch but need some help! At week 5 of flowering my plant took a pretty quick nosedive 5 days after watering with Epsom salt and molasses. I think I may have overwatered during this feeding, watered closer to a gallon rather than usual half gallon. Starting from the top of my plant leaves started to get brown spots and quickly spread to the top 2/3 of the plant. Prior to the watering my plant did have burnt tips which may have been nutrient burn.

At this point I'm not sure if the damage is really bad nutrient burn, zinc deficiency (damage started on younger leaves and in between veins), or something else. The photos show the damage. After the initial fast onset damage has started to slow. Since I'm hopefully only another 3-5 weeks away from harvest I just want to get her hobbled across the finish line.

I'm in soil and I'm feeding Neptune's Harvest Rose and Flowering about every other feeding at a ratio around 1.5 oz per gallon. This may be a bit much but I nutrient issues in the middle of veg and Neptune's is hard to burn with. I'm just not sure why it took such a nose dive after watering with Epsom salts and molasses. Hopefully I didn't make an incredibly newbie mistake. Any thoughts?

Additional info, my temps range from upper 60s to low 70s. Prior to incident I was keeping my humidity around 55%, but shortly after the damage started to show I lowered it to around 40-45% to try to align to VPD better but I think I bumped it too low. I've set humidity to be closer to 50-55% now.

Hey, is this your first time watering with epsom salts? also why did you feed her the epsom salt?

Man there is so much to unpack on this - You know there are easier ways to kill a plant jus sayin.

You kneecapped her right at mid flower , right when flowers are moving into later stage flowering and weight gain.
Whatever Frankenstein idea about Epsom salt and syrup did it nasty - torched / photosynthesis in leaf definitely affected .

Im betting this will give up the ghost or give you budlets at end or sooner.

Over fed and under watered the entire grow
Sad really let it finish
Btw explain the idea of feeding with molasses’s?
Cause I don’t think it is used for the way you think
Maybe flush it all and start over
Not want you want to hear I know
Just sad

I thought I had read about upping magnesium during flowering to help in bud formation. I can't seem to find anything on it now so looking like I had a brain fart.

While I agree with what you're saying, it doesn't really help me out much. I dug myself into a hole, I attempted to research on what specifically went wrong before posting, and now I'm asking for input from others more experienced than me on how to salvage her.

No more ” additives “ …. Just a simple bloom nute fed to her once a week so she can pull what she needs to work thru.
Simple ph of feed mix if liquid or a tablespoon or so of Dry fertilizer ( like Dr. Earth flower girl ) .

The idea of molasses is that it feeds beneficial bacteria in the soil to help with bud formation during flower. If it's over fed would you recommend a flush this late into flower? I'm honestly trying to decide which would do the least amount of harm, letting it ride out or putting it through the stress of a flush?

Being a new grower myself, take this with grain of salt (sorry bad pun).

Cannabis is very resilient. Give it some time and let it pull itself out. Don't give it anymore stresses. Best thing us 'newbies' can do, is simmer and let it do it's thing. Depending on how much salt you gave it of course, too much yeah I might flush it.

Don't worry dude, we all make mistakes on the firsts grows. This reminds me to my own first grow, my plants were also fine before I hit week 6, my problem was that I was not watering till runoff while using chemical nutrients, among other stuff.

What kind of soil are you using? Did you mixed it yourself or is it a bagged soil? How much epson salt did you use?. Molasses do feed the microbes in the soil, I used to use molasses before, you can use them every now and then at a rate of 5 ml of molasses per 1 liter of water, if you want.

You guys talking about the Epsom and molasses.

Big 6 in one cup. Bio-Righteous, Mykos WP, molasses, and yucca in another. And Epsom in the last one. I gotta water, but I'm procrasinating.

Doing less is more is a big take away from this first run! I really felt like I hit my stride as she went into flower and then I got a bit overzealous and messed up. For not using a net I'm super happy with the shape of her just using LST. Lots more to learn for sure!

Overwatering didn't do that. How much epsom salt and molasses did you use?

Base nutes until they're done. Start focusing on your next grow and don't make the same mistakes.

Good luck going forward.

It was a little less than 1tbs/gal, what I've used for pepper plants in the past. Definitely lessons learned for next time :). At this time point I'm going easy on the nutes to just get her across the finish line. My biggest concern is the rotting going into the bud or mold. Hoping she finishes up closer to the 10 week mark rather than 12+.

Appreciate all the replies everyone!

1.5 ounces of 2-6-4 per gallon is CRAZY imo, I dont think you based this upon a measured approach with a plan.

Ime, that is 5x to 10x the dose it should be given! Your feed program created this. Magnesium added without calcium and iron in mid flower also is a risk if you dont know your situation clearly.

So my 2c is way overfed. Look at feeding charts and the amounts...1.5 ounces of that is like adding PK boost every other water!

Remember you can always use less anytime your using something to fed start out with half doses and go back later add more if you find fit...good luck to you...what's your style of growing coco or soil? Bottle fed?

The instructed amount is 1oz/gal. I agree what I was feeding her was too much. I had some deficiencies prior and got too heavy handed trying to fix. I was watching for signs of nutrient burn but the plant went from having slightly burned tips, and I was starting to lower dosage, to just looking ravaged in a matter of days. I feel like something in the Epsom salts/molasses really accelerated something that caused her to crash. Probably the lack of calcium/iron you mentioned. Really appreciate the info and feedback!

I'm using Ocean Forest this run but may look to switch to an organic soil mix next run to try something different. For nutrients I'm using Neptune's Harvest tomatoe/vegetable for veg stage and then rose/flowering for flower. It's not aimed at cannabis specifically but friends and I have had great success with it in gardening. Once I figure out correct feeding I think it'll fit my needs going forward. If I wasn't using it for gardening I'd go with something more cannabis specific.
