Brown rust spots on oldest leaves
Brown rust spots on oldest biggest leaves with curling inward - the rest of the flower is fine, just some occasional small yellow spots. No sign of pests. Maintaining pH ~6.5 but have soft water. Suspect cal/mag deficiency or nitrogen toxicity. Thoughts?

Critical Purple: Leaves slightly yellow.
Just started my first grow. I1 placed the light high in the tent and the leaves slightly turned yellow. I lowered it yesterday to 18” over the top on the plants. Just wondering if I am on the right track to solve the issue. The plants are still growing. Minimal nutrients 1ml/gal.

Day 4, after emerging. Is this coloration on the cotyledons okay?
Humidity is 55 - 70, temp is around 20-24c, 50w full spec led It's my first time, and i think i have been watering it too much I also fed it 2-0-0 npk water with 4ml per liter and I since learned it's not okay. Will it recover? Is this too little grow for day 4?

Brown spots watering in coco multiple times a day
Seeing brown spots on the leaves. Assuming it's a calcium deficiency. Added another ml/gal of Cal-Mag for the daily feeding. Besides that, what else could it be? Also, at what point do you water plants in coco twice a day?

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

I have lots of yellowing on the lower leaves of one plant. After reaserching I think it’s a nitrogen deficiency. Also today I’ve noticed lots of teeny tiny white/clear bugs! I’m super anxious about it, thinking my plants are goners. Any idea on what they are?

Leaf discolouration. Nutrient deficiency?
Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?

Some brown spots showing on the top sugar leaves. I suspect it is due to the cooling fan of the light blowing down hot air? I've adjusted the fans to blow air directly over the top of the main cola's and I increased the light distance.

bottom leaves yellow
Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater
