Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!

Week 2: One of the plants still doesn't look good + other beginner questions :)
Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

Slight discoloration in the leaves
The leaves are starting to get slightly discolored on the edges, what could be causing this? Could it be the white flies? Or could it be too many nutrients? I am giving the plant a bit of Canna A and B, although it's meant for hydroponic, it's all I have at the moment.

Blotches on Haze Auto leaves (End of Week 8) - Diagnosis?
Could someone look at the last few images of my Haze? Is this a deficiency? What should I do at this late stage? Otherwise it seems okay, other three Autos are doing great. Block would look different? Very crowded tent. Fairly warm 25-30c. Humid 55%. Feeds 600ppm. Cheers!

What are these yellow/brown dots and how can I prevent more from developing?
Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.

Bugs, spiders or fungus?
Hi everyone, what should i do with this in floration? Neem oil? Soap? Im starting the 9 week and i think that if i use neem oil now, it will leave some taste on the buds. I touched some leaves and the white marks stay, it isn't powder, but is white. Thank you 💚

Hi Growing-Community! Today I detected small brown, rusty spots at the top on new leafes (see pictures at week 4). Anybody any idea what could be missing my Nothern Light-Girl? I transplanted her to 11l-pots with BioBizz-Allmix last week and gave her just water (PH 6.5)?

Blotchy Leaves Problem - January 27 (Day 23)
In the last 24-hours all three of my plants have started to show signs of blotchy/irregular colored leaves. When I touch the blotches they are crisp to the touch. I have a really cheap pH meter, and I've been feeding at 6.5 pH. Is this a pH issue?

Calmag deficiency
The leaves on my plants seem to have some markings appearing, I havent yet given any calmag. The plants are in their 4th week from planting seed. Also seem to have some nute burn going on. I do have some biobizz calmag, should I use this and if so at one strength?

Some kind of deficiency?
World of Seeds Strawberry Blue. Pretty slow, uneventful life this far (on me). What seems to be wrong? Veg and a lot of light. FoxFarm soil. Half to full strength of the General Organics line. Bottom main fan leaves going first. Please refer to pictures. TY for any input!

Healthy?
Sie wachsen zur Zeit sehr schnell allerdings haben manche Blätter Flecken wie man sehen kann. Die ersten Wochen habe ich leider mit einem zu hohen Ph Wert gegossen (ca 8) dies habe ich jetzt aber angepasst und sie bekommen ihre 6,4.Vielleicht Nährstoffmangel? Bio Grow hinzufügen?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same. I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…
