Thanks for the info. I'm trying the neem oil since I already have it. I'll spray it on my next batch which already is showing signs of fungus. I'll keep the Daconil in mind if the neem oil doesn't work.

neem works pretty good, but it does taste and smell like rotten garlic...that is my one problem with it.
as long as you don't use it in flower, no problems, i would try to use almost anything else if i had to in flower...although i'd be ashamed of myself for allowing something to go that wrong to begin with

New colors…

Is this still just pest? I don’t think I’ve ever seen this color combination before.
Or a phosphorus deficiency?

i'm going to guess too much calcium and N, which leads to not enough sulfur....
where is it showing up first? upper or lower leaves?
if its lower first it may be sulfur, if it starts at random spots on upper and lower leaves it may be manganese deficiency...
but i'm not a horticulturalist, i just play one on t.v.
if anyone else has a suggestion, i wouldn't be offended

I actually used that site to try and figure out what was wrong. I guess because of the purple and bluish color I went towards the phosphorus deficiency. I did think this at first. I also have zero experience with this kind of symptom. So there’s that too @_@

Noticed the Log link in your sig so I checked it out. My first thoughts after reading it is pH or lockout. You're feeding organics and salts in FFOF.

Do you ever water to runoff? And have you checked the soil pH?

Soil ph is 6.8, I have given no nutrients just water for about a week now thinking toxicity was my issue

that looks like advanced calcium deficiency to me...give us some details, you in soil or coco or....using nutes or dry amendments or....room temp/RH/how much air flow....

My plants are in 5 gal pots with the top half 50/50 happy frog/o.f. and the bottom half strawberry fields.
I feed the weekly fox farm soil schedule on Sundays and extra tiger bloom on Wednesdays...
Cal mag every time I water..
Ph water to 5.8 to 6.0

ph is a little low, around 6.5 in soil is usually a pretty good target.
i think you have too much potassium in your mix, which can block the uptake of calcium.
i think if you cut out the extra tiger bloom it would probably help.
but i only play an expert on t.v., i would seek a second opinion, as well.

One of my leaves started going papery in between the veins. Just in the last few hours

Is a two-week-old gelato auto

In a 50/50 blend of ffof and 70/30 coco perlite

Getting ph 6.3-6.7 water with tribus

Planted with dynomyco.


Got a new light yesterday which I considered as the source of the problem. but this plant is in the corner and way shorter than everything else in the tent and this leaf in particular is receiving the least light on the plant so it would be odd if it were the one that is burning.



Lmk what ya think please. Maybe it is that darn light!

almost looks as though it's cannibalizing the way the chlorophyll is draining from the tip.. how's the air turbulence?
