Mottling shiny spots in leaves/ nitrogen claw
Jerseyfresh39
started grow question 6y ago
What is the cause of the mottling on these leaves is it some sort of toxicity? Please look at my last diary entry (week 4) for info on recent feeding.

Hi
@booberry39
it seems to me over-fertilization, just give water with PH adjusted to 6 for a good day and wait for your plant to recover before giving it feeds again. good luck mate 👍

It's over feeding. Just give it plain water and let the planta feed itself on the soil

Should I remove foliage affected by deficiency, or just let it ride?
Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic). 1) Can someone confirm CalMag deficiency or something else? 2) Should I remove affected leaves or leave them be? Thanks

What went on here??
This is an Orange Sherbet I grew in Happy Frog with the FloraGrow series. I harvested early because I thought the plant was dying, and couldnt seem to stop it by flushing. Does this look normal for a plant being flushed out? Should I have waited?

Discolouration of some leaves
Is the colouration of these leaves someone to worry about? She’s a young, 2 week old Wedding Cheesecake auto and I’m new to growing and just want to make sure she’s ok! She’s growing in a 70/30 split of coco and soil and has only been fed water so far! Is it nute time?

Leaf issue
Got an issue with some leaves turning this colour. Anyone got any input? We are nearly 7 weeks in, growing in compost and only feeding 1ml/ltr. I’ve also attached a picture of the whole plant. Leafs at the bottom seem to be turning, the ones up top all seem a good colour.

The yellow spots that were seen last week have multiplied and started to appear on newer leaves. I should mention my tap water E.C is 0.8 so quite high. I still however added calmag this at it seems to look like a calcium deficiency. Are they to young for one though? Thank you

Which volume of soil/Sq metter do you recommend for the best production ratio? I mean number of pots and his volume. I am using 4 led tubes of 20 watts and 6500k is it the best way to germinate and grow the plants for 15 days?

Brown leaves - what am I doing wrong, folks?
They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

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.

Any ideas on what's going on with NL-2? Fan leaves are discoloring, interesting pattern. From Websites, I'm thinking a potassium problem, but am not sure. And am not sure how to correct this close to harvest (3 weeks give or take). Thoughts?

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.

Do these random spots mean nutrient burn/deficiency, or is this normal?
I have been feeding my plants 1/2 strength FF once weekly since week 3. The plants seem to be doing well. One has twisted leaves but seems healthy. But the plants are displaying random spots of yellowing. Is this normal or indicative of some kind of nute issue?

I suspect I have either leaf septoria or a calcium deficiency. I'm 2 weeks from harvest. The top leaves appear to be affected. The smell has changed (sharper). Not sure what to do from here. All advice appreciated :)

Calcium Deficiency? pH problem?
Brown spots on some newer growth now on both plants. Canna Terra Flores brings the pH of water down too much even at a half dose. I didn’t think I’d need to adjust pH much in soil. Any suggestions at this point? Thinking to just feed plain water to bring the pH up at the roots

Little browinish/beige dots near leaf veins
I noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress?

Q1) My Dinamed #2 is looking a little concerning. Been spraying with freshly made neem water. You think its leaf miners or could it be a mag def.? Q2) I'm seeing yellowing tips on some plants (old full-leaf yellowing from pre-transplant). What could it be? Organic nute burn?
