brown spots?

What's this? Looking at the deficiency chart and don't see it.
FFOF + added perlite (25%) and dolomite lime (1 tbsp per gallon)
also given tea of organic blood, bone, kelp, etc. + earthworm castings, obviously plenty of nitrogen from the dark ass color!
tap water through carbon filter when dry, then soak
vegging
temps 70-80
the dark sativa on the left is Super Silver Haze and is about 2 weeks younger than the Trainwreck on the right. But the SSH is getting worse spots than TR so not age apparently. SSH is really dark and has a sheen to it, also some upcurled leaves on both.
Anything else you want to know? just ask

SSH














TRAINWRECK

Why you adding lime?

to keep ph balanced. had some problems with ph in the past i think, might have been the water. shouldn't pose a problem though eh?

Lime raises pH. If this buffer has built up in your medium then your pH is high.

Grab a cheap soil pH probe from home depot and it will get you in the right ballpark. My bet is you're pH is high.

I was thinking FFOF was acidic, hence the lime, but yea good call i was thinking ph too, i always seem to get these ph issues! lol anyways, yea i should stick a soil meter in it.

If your ph checks out, consider a possible cal/mag issue.

i thought possible cal/mag too, but i think the bone meal should have the cal covered (?) and the mag def looks different on the chart

btw what is best recommended organic cal / mag fert?

Yes, you would think. Missed it in your first post.

I couldn't tell you what the best brand is, I'm using General Organics Botanicare Cal/Mag + but only because it was what my local store had the day I needed some.

the trainwreck does look like possible mag def with the dark veins, but the ssh doesn't seem to have it but has worse spots.
maybe a combination of cal / mag and ph

Doesn't look too bad and overall health is good so don't sweat it. Get that ph meter and go from there.

Sort out pH and you'll be fine. I put cal/mag at the bottom of the list with the size of plants and soil medium you're likely fine presently.

let's say ph needs to be lowered, what is recommended?
