Dry Brown Spots on Lowest Leaves

Hey All,

I have some dry brown spots forming on the lowest leaves of my unknown bag seed.

Not sure if it's nute burn. My bet is on that. I watered her two days ago with 1/4tsp. of Big Bloom and 1/4tsp.Grow Big FF nutes. in 4cups water at 6.8pH 580ppm. Soil grow in FFOF.
Transplanted her about 1 1/2 weeks ago into a 3gal pot. Think I added nutes to the soil too soon considering it was just transplanted into a "fresh" pot of FFOF soil?
It's 36 days into Veg. It got stressed out early on from over watering and over fertilizing. I flushed and everything seemed to be ok.

Signs started showing on one leaf, maybe early yesterday, and by end of today it had spread to more leaves. Should I flush? Right away? Or should I hold off and wait until the soil dries up, so I can avoid overwatering?

I appreciate any advice you guys can give.

Thanks,

This leaf is the newest to be affected. Can also see(out of focus) one of the other leaves with it.






You can see the earlier nute burn/overwatering damage a little on the center leaves. I cut off the dead tips, but I haven't had any growth from those leaves. Instead a node shot out the middle of the stem below the leaves.

Most likely Nute burn. Nitrogen could be off or Ph fluctuation. You can flush ive done it before but it doesn't look to bad. Try to flush once it dries up more if possible. When i flush i put my pot in a sink and i do three flushes over maybe an hour or two period. Basically pour good ph balanced clean water nice and slowly all around the top of the soil wait until its finally stops dripping out of the bottom and repeat the process two or three times. Works great for me. You should be ok try not to stress it to much but def keep an eye on her.

looks like a calcium deficiency to me. try to add some calmag and always add a weak nute solution to the water on last flush that way you dont starve the plant

Thanks for the advice. I've held off on flushing for today and will see what it looks like tomorrow. The spots haven't spread to any other leaves or worsened the current the spots. I'm keeping a watchful eye on her, but I wonder, if it doesn't worsen is there any reason I should still flush? Regardless, the next time I water I will use plain pH'd water.

I bought some Cal/Mag just incase that is the problem. Are there any other signs/symptoms of calcium deficiency?

Appreciate any of your advice.

Thanks

Theyre dying! Just kidding, they look fine, besides the burn. Stop feeding. Dont flush, just run water and dont feed. Ffof is good soil. Id doesnt need anything with step up transplanting at normal times. When your a week or so from flip add some grow nutrients , when they flower step it up for the ppm and coast through it, taper off at the end and youll have a stellar harvest. Soil grows plants. Not bottles of fertilizer.

always good to see this guys advice

Thanks for the advice. Good reminder about soil growing plants not fertilizer. I'm a stereotypical first time grower, overwatering and over-fertilizing. Gardening is teaching me some much needed patience.

I don't plan on transplanting to a bigger pot. I'm growing in a cabinet with 3gal. pots. Should I just top dress some new soil in a couple weeks instead? Or can I just add certain nutrients to the soil to supplement?
