Hi
@Tictac789
! It looks like you applied some spray during the day, and as a result, this droplet left some yellowing mark. I'd recommend not to spray anything while sun is shining. Hope this will help, happy growing! 👊

Temps seem a bit low, or could be burning from water spots/nutrients. Seems healthy regardless! Good luck on the rest of the grow! ✌️😎💨

What's wrong?!?
Help! I thought I had this. Is this calcium deficiency? I've been using treated water (1tsp CalMag+ 1tsp Grow Big per gallon). It's just getting worse. See photos and descr. from past few days.

Plant issues... How long to harvest?
Could someone please look at my (only) diary and give me an estimate on when harvest might be? I have microscope pictures up . I think I see cloudy trichomes with the possibility of a few amber. Maybe ready now? Not sure but hope to harvest before plant gets much worse. Thanks!

Hi Growmies, I have some drooping to the edge of leaves and discolouration. I've been watering every two to three days and live in a soft water area. Is this due to under or overwatering or is there possibly a nutrient deficiency. Thank you ✌️

Any ideas on this?
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.

Curled leaves occurred in both veg and flowering tents only to my purple trainwreck plants. Checked leaves with a loupe and couldn’t see signs of any pests at all. Only occurring on my PT plants in all tents. Other strains seem 100%. Only on large fan leaves, any ideas or help?

Plant #3 (pic above) started as a sprout with discoloration. Now on its 4th node, the plant is still affected. Some other plants seem to have it to a lesser degree. I learned it may be TMV, but they are healthy and growing well other than this slight discoloration. Any thoughts?

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!

There is some damage on the first set of leaves, I was thinking it's either due to fungus gnats which I am in the process of eliminating, or an early cal-mag issue from before I increased my nutes. Any thoughts?

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?

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)?
