What causes these burned leaf edges

[suckabusta]

Any ideas on what this might be? It seems to effect only the permitter of the tent.

Currently wk 4 of the HSC blueberry muffins. All organic, using Gaia green amendments. biobizz heaven and top max, mammoth p, and sugaree once per WK as per the instructions on the bottles.

I'm using the AC infinity Evo6 in a 3x3 set to 50% which should be 250w. Temps and humidity have been perfect.

I feel as tho it's light burn/the mylar reflecting light harshly along the edges of the tent. Is the light possible too big for the tent?

I top dressed them about 6 days ago using the Gaia bloom, once tablespoon of Gaia 444 and some worm castings

Tent seems healthy otherwise.

3-4 weeks into flower? My opinion is potassium def, let some others chime in though

Could be cal def as well, but looks like potassium to me

Could also try backing down the power a shade if you’re maxed on light height to let them recover a bit

Could definitely be possible, I'm hoping the amendments take effect within a few days.

Weird that it's only a long the perimeter though.

Def a potassium issue. Burnt edges/serrations, tip burn that creeps and the tip curls up with some necrosis and trippy colors. def signs of potassium def. Also looking like she wants some phosphorus. Purple leaf petioles and leaf attitude (curling down). Could just need some more p and k (they start wanting more around now) or she may be having trouble accessing it. Can get locked out by too much calcium, ph, etc. If you have been feeding light and just top dressed, I would suggest she’s a lil hungry and let her eat with what you’ve added. If those potassium signs start spreading rapidly tho, pretty good chance of lockout.

I think it might be calcium you have some browning going on with your tips too not 100% sure

Could be potassium too

If the rest of your tent isnt showing sign of light stress i doubt thats your issue

Ca is immobile and deficiencies will generally show up in newer growth. They also are not using a shitload of it by this point. Not impossible, but I would bet on some p-k issue. Be careful if you add additional ca. it is antagonistic to potassium and can aggravate a k deficiency if that what you’ve got going on.
