Can someone look at this leaf problem?

this showed up today, watered yesterday 6.6 ph going in ,1 tsp epson salts per gallon, run off was 7.2 ish for all 3 plants, watered phd 6.2 till I got them down to 6.7 or under. 18 days into flower

if your in soil ....slow down on reading the ph....its not going to help most of the time. SPECIALLY with runoff ....thats a waste of time and batteries. what foods? how much ? is that soil ? i would need to see the whole plant but going by that leaf only , the plant is eating itself already ....it needs food. If your using "bloom food" only then give her a big dose of veg food instead ....twice. ALL plant HAVE to have plenty of nitrogen throughout the whole cycle ....you just lower it towards the end.

Leaf septoria

General organics, bio bloom, bio bud, cal/mag, bio marine, ffof soil, feeding per the chart, ok so I’ll add some grow,
Bloom 2-4-4
Marine 2-3-1
Bud .5-0-1
Cal/mag 1-0-0
Grow 4-3-3
So I should add bio grow, at full strength 10 mil, for two feedings?

I’ll get a picture of plants now

yes , i would.

i havent seen their chart , ill give it a look see and be back.

i dont see why they got you using so much calmag but thats just an opinion. i have never used that line. ive seen plenty of good results from it though.

PICT of one plant

yea one full dose of nothing but grow.
are you feeding every watering ?

Feed, feed, water, should it be all feed.

Yo! Read up on leaf septoria. Or not.

shes hungry , i can tell you that . looks more like nitrogen only though.
onto leaf septoria... whats lights are you using ? basically im trying to figure how high your humidity is ?

edit: if your using hid and plenty of ventalation then you can almost rule out septoria.

Just hung a new hlg600, it’s at 26” humidity is 35. Temp 77 to 68 lights out

if your humidity has stayed that low then you just need to give her a couple feeding of grow followed by a feeding of normal followed by a feeding of plain water with molasses

and you'll need to keep a fan movin

Fan always , around the top of canopy, but going to get one that oscillates, what kind of molasses, and how much per gallon?

sounds like everything is good .... any blackstrap molasses ... grandmas is whats usually at the grocery. 5-15 mills per gallon ... it feeds the bacteria in the soil.

bio marine also feeds the soil. its a good additive

Ok , they fed, they love the new light, the smell has really kicked up,
Thx for all your help, I think yesterday I pretty much Flushed them getting the ph down, I’m not measuring anything out the bottom from now on, what goes in is between 6.5 an 6.7 , that’s what they get.

Lovin’ the light
