answered grow question 6y ago
Don't think so or you'd ewe it on more than one leaf. Could be just spillage of nutrients burnt on by magnification of the light

Leaf changed color and spotting, help!
Any idea what I need to do to fix this? I think I over fed and then I recently did and RO flush. Then I fed it calcium herkley and harvest recharge in a little general organics bloom.

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

should I be worried about those little white spots, do they indicate on some kind of deficiency or they will go away eventually by themselves? I mean there aren't much but still, got me little worried.

Fast-growers starting to show issues.
Got some issues on these fast growers. I've been treating it as a cal-mag deficiency, however I've been feeding calmag for two weeks and its only getting worse it seems. Any thoughts? PH is 6.0-6.3, PPM 444 feed, RH 47-50%, Temp 77-81f.

Twisted/mottled growth
Not a happy plant, was on a windowsill in 30c back 6 days ago and think the roots were overheated? Transplanted to final pot and have been foliar feeding since but no improvements (gained about 3cm in height!) Found caterpillars yesterday so removed leaves. Will she bounce back?

Hydroponics, i need a second or third pro opinion. Just a Deficiency? bad pH? (I alreadt did a partial water reservoir change tho)
Yoyoyo! If someone of knowledge could help me here, I would be grateful So I think it's a Magnesium deficiency, caused either from my too low pH (5.2) or too much CalMag (only used 1,5ml on 10L) I gave a more in-detail description on my diary. lower leafs are "crispy", not smooth

What do i need to do now?
Ok so this has been living on Oceans FF soil and 6.0 ph'd water with hydrogaurd. Last week I added a little Beastie Buds and a very little calmag b/c i thought i saw some red stems. Deficency or excess? Has the soil ran out of food?

Nutrient Deficiency
Is this a PH issue showing or nutrient deficiencies (possibly caused by bad PH anyway, at 6.2 atm higher from earlier in week.)? Possibly magnesium deficiency, looking at pics. Anyone confident? Been hot in tents as well but water temps kept decent about 68-70.

Nutes too early?
The leaves of my northern lights look a little brittle and discoloured, maybe the small amount of nutes I gave were too early?

What's the issue with this leaf?
Can anyone help identify the issue on this leaf. Dreamcatcher is the strain and I can tell they were a reveg. It was root bound and I thought it was an issue with the roots. After transplant outside and sprayed with my IPM the plant has recovered but still has a few like this?
