If that’s just the bottoms, I wouldn’t worry—- looks like there might be soil on the underside of the leaves? Flip them and make sure you don’t have spider mites.

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

Does the paleness concern you?
Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil
On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

I have a deficiency. Can you please check out my pics and give your advice? I thinks its a Magnesium deficiency, am I correct? Increase CalMag? Flush with extra water? Any tips would be helpful.

Early senescence on Runtz?
Based on your experience growing Runtz and/or the pictures posted below, what week would you say we're in? I'm asking cause leaves are yellowing and unless I overwatered them it looks like a very early senescence, no? I'm a newbie so there are obvious things I don't see :) Cheers

Weird leaf
It seems one of my leaves has become very oddly curled up. It has very slight brown spots with a strangely curled up tip. As seen on Week3-day19. Can anyone identify some sort of problem like excess or deficiency of nutrients?

Yellow discoloration again
I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?
