MMSC16started grow question a year ago

Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

It's probably a Nitrogen deficiency. It seems like you are applying a bunch of nutrients, that can cause a lock-up, so as to say that there is enough Nitrogen in your soil, but there is so much more of everything else that the plant has stopped eating properly.

@TheGreenRanger Thanks so much for your response! I've top-dressed 1 TBSP of 4-4-4 (instead of 2-8-4) as it has higher Nitrogen percentage. I'll let you know how it goes over the next week! It's very mobile, I've noticed it spreading to the next oldest set of leaves. My concern is that there's too much Nitrogen now, and perhaps I'll swing into a toxicity, Very novice and appreciative of your reply!

Nitrogen deficiency or could it be nothing In the pictures you see some yellowing and small spots. I don't know if it's Nitrogen deficiency or not because it stays with those two leafs.

Starting to yellow So I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?

Advise to flush or feed in Veg Does this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? Th Is this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks
