Mephisto Toof Decay. Burn? Deficiency? What do you think?

I'm trying to decide if its time to feed, or if they are getting burned.

4 x Mephisto Toof Decay
Happy Frog Soil mixed with appx 1/4 Coco
600w MH and 600w HPS
temps 70-80 Fahrenheit
RH is 50%
Just started week 7 from sprout
NO Nutrients to date, Just water, and I've been alternating my Ph between 6.5 and 5.9 give or take a point.

Started noticing a few yellow leaves the other day, but the tips look burned, and I've always thought that meant too much food.

otherwise they look amazing i think.

I don't want these ladies going downhill...
any advice is appreciated!
Thanks

Needs a p/k feed imo ..... Can't remember but one of them shows as necrotic spotty leaves mid plant ..... And coco tends to leech ..... Mic drop and walks away .... Jk jk



I love the stature of the mephistos. They are like the pitbulls of the autoflowers

*picks mic up*

Thanks man! I have canna bio Flores.
That's pk right?
Was thinking about feeding 1/4 to 1/2 strength on the next watering.

I agree about mephisto. I have a bunch of their gear going right now!

looking nice! I'd give her and drench and foliar spay of epsom salt.

hell any bloom will work .... i think its a P def if i remember right a K def gives the plant a blue/green color and delays the onset of flower ..... think P and cal-mag is what the coco mainly leeches , thats if im even remembering correctly have a bad case of CRS lately

Thanks for the advice man!
Well see how things go.
I fed them 1/2 strength, well a little less than 1/2 but close. The bottle says 1/2 oz per gallon I used a tad less than 1/4 oz
hopefully the yellowing stops.
fingers crossed

Here's a few new pics from today... Obviously the damaged leaves won't come back but there doesn't seem to be any new damage..

I'm going to feed again today but 1/2 strength this time.

Your problem is they are hungry ... They are pulling nitrogen from itself.
Should have started bloom nutes ... Medium may be exhausting.
Leaves will not recover but they need their fans so give 1/2 bloom to start.

Autos WILL have leaf fade at end , no matter what .

OP, is this your first time with Mephisto? i'm thinking about trying some autos next run and the pix of the strains on their site look impressive. hard to choose a strain though. was looking at walter white or the sour bubbly crack.

This is my first Mephisto Order and I got a bunch going at the moment..
So far i've finished
Sour Crack - Fucked em up, my fault,,, shit yield but AMAZING smoke
Toofless Alien - They are in the dark for a few days before the chop

I've got the Sour Bubblin Crack going , and Toof Decay, and Sour Blues

Will definitely be ordering from them again

I don't think you can go wrong with any of their gear.

Feed them things. They look to need everything. They need a balanced feed because your lacking everything.

How much are you watering them? With organic soils you don't want aot of run off. You strip nutrients and the soils ability to buffer pH when you do that.

Feed them and back off the watering a little.

They get a gallon usually once every 5-6 days depending on how dry the soil is.
I use saucers so run off isn't a problem, most of the time I water from the bottom anyway.

I've since fed them half strength, this is my first go around with mephisto and i'm staying real light on the nutrients since I'm not familiar with them.

I ran the mephisto Heisenberg hot. It handled it fine.

Mephisto is the shiznit.

nice man! I may try Heisenberg Next... It is hard to choose and I ordered like 7 strains!
The Sour Blues I have going now got burned and I haven't fed em anything.. wicked nitrogen excess.
