Any ideas on this?

started grow question 6y ago
I'm guessing this is some sort of deficiency. Some of the spots are rust like and occur and young and old leaves. Any opinions? Advanced Nutrients 3 part. No supplements.

Looks like Calcium deficiency to me mate I'd foliar feed the leaves with some calmag and some chelated iron couldnt hurt either

I agree calcium deficiency is most likely the problem. Calmag will solve the problem.

Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?

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.

Discolouration on fan leaves
Getting a white discolouration on my fan leaves. Thought it was residue from watering with nutrients as sometimes water will land on the leaves. But it doesn’t rub off, some parts look like it’s scratched into the leaf, some parts look almost bleached. But also considering PM?

Are these leaf changes normal?
This is first grow to make it this far. I am unsure if my leaves are just doing their thing; or if I have a problem. She is an auto-flower. I am on day 74 from sprout, day 35-ish from flower.

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.

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?

Deficiency?
I noticed this spot on one of the fan leaves. It only appeared in the last couple of days. I have been feeding small amounts of calmag and biobloom. I looked at deficiency charts but I’m unsure. What could it be?

Hi there.I’m almost sure it’s a female (pic). I got my first bugs. By the look of it I guess it’s spider mites. What I did so far is spray top and bottom leafs with a neen oil solution after lights out and since I saw it on only 2 of the bottom leafs (removed). Any other tip?

Problem came back
Hey mates, sup? This week the problem is back, milder than last week but still here. I haven't added anything to the soil yet and I'm worried about it. What do you think it should be? Overfeeding, magnesium, light?

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Is this septoria or alternaria? The plant is doing well, buds are not affected (at least not now) so I hope it’s septoria. Few weeks till flowering complete, do you think I can carry on with it? Please tell me it’s septoria and not alternaria. Thanks to anyone that will respond
