I've had this before, mine was due to calcium/magnesium deficiency, are you using calmag as part of your feed?

Leaf Discoloration
I woke up this morning to only one of my strains having discoloration on the leaves. Still looks extremely healthy but I don't feel like I'm overwatering and I'm definitely not over fertilizing. Need help before problem gets exacerbated. Thx in advance.

problems with leaves
Hi, friends! I have problems with two leaves. Tell me, who has experience, what can it be? Disease, pests or some kind of mechanical damage? The growth feels good, it grows, I don't see any more problems, only these two leaves bother me. the last three photos labeled "Problems "

Touching buds while drying
Does touching the buds at all while they’re drying reduce potency? I’ve been checking them daily and touch the odd one from time to time. Should I just leave them alone and focus on snapping a stem to determine if they’re dry enough?

Help, what are those weird yellow spots in late veg?
Hello everybody, I've checked in on my plant after I was away from home for 2 day. Now I come back to see these ugly yellow spots? During day 23°C / 55% humid. During night 18°C / 50% humid. Checked the whole bud, but no insects. My other ideas are mold or stress from the light?

Not sure what's causing these purple leaves and leaves drying out. Plant overall seems unhealthy near the end of flowering, any suggestions appreciate
This Dos si dos Auto has been struggling over the last couple weeks with upper leaves turning purple and drying out/breaking apart. The buds also look strange to me but that may just be from my inexperience. I'm growing in organic soil and have dry amended twice, 18 days apart.

What's my problem here?
I have some weird leaf discoloration on a couple of flowers that are directly under the center of my light. What do I need to do? Also this is what my lowest (younger) leaves are doing at the bottom of the plant. Any tips? included a pic of a flower in the corner that looks fine.

Krank oder verbrannt oder nur angeeckt
What could that be? There are no insects or anything in the tent. I use half the recommended amount of nutrients, and the light is 70cm away (can't go higher, the tent is too small).

Phosphorus? Potassium? CalMag? What is going on here?
So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Rust spots on lower leaves
rust spots on lower leaves on mainly one strain, started at tip of leaf. Happened after res change and had PH swings during that time until it was adjusted/settled. Full EC again. PH swing? Maybe cal(or)mag issue? PH is back at 5.9 now, running bennies. Maybe Slightly droopy? Thx

Potassium deficiency?
Is this a potassium deficiency? Before it happened my water was on 930ppm on the 4th week of flowering. now the 5th week has started and to correct this problem I have added 1 ml of pk 13-14 to the diet. So ppm is now 1100. Do you have any advice? thanks a lot to everyone!

Deficiency or toxicity
Stems are really purple, leaf stalks and veins also purple. Something is up. Some leaves starting to show burn spots but not many. She's a bit down because she needs a feeding. Is this magnesium deficiency? Should I be upping my nutes at this point this late in veg end of W9?

Has anyone had “tobacco mosaic” before? It appears my plant may have it (Unless something else is wrong). It only appears to be on a few leaves. Im wondering how effected your yields were. Thank you.
