First Indoor Grow! Need some help please!

[soysaucee]

Hi guys its my first time posting here. I have done a few outdoor plants over the past 3 summers and felt it was time to try an indoor grow.
I'm growing (2x Purple Punch, 2x Mac1, 2x Lemon Sorbet, 2x Kush Cake)using LED they are currently 4 weeks from seed. They did very well the first 2 weeks then started showing necrosis patches along with what looks like bleaching to me. At 3 weeks I reached out to a grower I know he said they need food, so I started my feed regiment. Please help me id my issue, I have started checking ppm of feed and ppm of run off

Medium: 50/50 Ocean Forest/ Coco Coir
Temps: 73-80f
Feminized photos

Please let me know what other info to post

this is how the damage looked at 3 weeks

I'm thinking they need some up potting, but there may be other issues at play. Some of the soil growers, @013 should be able to help!

Hey Soysaucee,

Welcome to the forums at 420...! BTW’s nice plants!

I do see a combination of things. What’s your nutes? Are you using cal-mag? How often do you water?
Also what size are those containers? Are these autos?

Both ppm and ph of your runoff is useless, yes it’s gonna be high or off because you are washing nutes & find sediments out every time.... then if you adjust your input ph or ppm to change to output you really get in a circle jerk, don’t chase that rabbit. Think of runoff like Vegas... what happens in runoff happens & the numbers mean squat.

Your watering tech prob looks ok.... but to be certain those plants should go 4 to 5 days easy with no water. If you are adding water every day or two or three that’s not good....if that’s the case then we need to hook you up with Emilyas watering articles. This is for soil grows not coco... cause coco is different.... but for soil go hard on wet dry cycle in veg but in flower keep it moist at all times

I’ve got to jet before long but Rexer and this crew will get you sorted.

Also coco can help with drainage but it weakens the FF. At next upcan I would skip the coco and go long on the FF, coco is totally inert - no goodies for your roots to munch on. If these are final pots then it would help to know what size you’ve got? I think these are autos but either way that soil will run out of steam soon since the FF was cut with coco.

maybe remove the damaged leaves and see if the new ones repeat the same symptoms? If you fix the issue the damaged leaves won't return so that's at least how I wait and see if whatever issue has been resolved. Try remedy "A", remove bad leaves, wait and see if the other leaves repeat, etc.
It could even be something as simple as nutrients splashed on the leaves closest to the soil and burned them!

I gonna revise that - your watering tech prob looks ok.... but to be certain those plants should go 4 to 5 days easy with no water.

Ok thank you guys, So for my watering I wait until the medium is dry to water again, takes about 5 days
I am following fox farms recommended feed schedule at half strength, I am also adding (1ml superthrive, 2.5ml Terpinator, 1/2 tbls Molasas) per gallon, My PPM going in was 700 and PH 6.5. I have not added cal mag and I was thinking that was possibly the issue. I'm also concerned my medium is not draining well

I am going to removed damaged leaves and see how we go from there

also, your leaves won't stay the whole life of the plant and the older, lower ones will die and drop off at some point

That I am very aware of, this is just my first indoor grow. I have done a few out have just never ran into this issue and would like to figure out what's going on

Apologies I was mid edit and got tied up in another matter at home.

Hey - what size are those pots or buckets? Are these autos?

The containers are not filled with soil, for soil grows you want to use as much soil as possible, don’t compress the soil but fill it to the top.

No worries thanks for the help!, they are in 2.7 gallon pots 50/50 soil/coco, left about 2" room at the top
they are not autos, they are fem photoperiods

Ok upcan but not for a while, get them healthy as ever before next jump, pure FF no coco.

should drain unless not enough holes. Tilt or prop each of pots at 45 degrees angle for 5 minutes to see if it’s still holding water.... best of luck Soy!

see what else comes in here too

What's up guys so 6 out of the 8 plants seem happy and healthy, but my 2 purple punches are struggling last night I noticed a waxy/oily shiny residue on fan leaves this morning the seem to have dried up but now have rust spots. Cal Mag was just added to my feed regiment
