Hi mate, believe this is caused by PH issues. Makes it look like a calcium deficiency but its a slight lock out... Just keep an eye on your PH and do a slurry test of your soil to see if she is too acidic or not...Good luck and happy growing

Small brownish spots forming on lower leaves. Need help with diagnoses!
Hi all. Just migrated plants to new tent/fan. I have much better environmental conditions. Now I have these leaf spots. I've included recent measurements. I was going light on the CaliMagic using 1/2 tsp per gallon. Is that my issue? Roots look good. Thanks everyone!

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)?

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?
Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...

The middle plant is somehow very bad off, while my other 2 plants seem fine, making me think its not humidity/nutrient related, but i really cant imagine what it would be, has anyone experienced this before? it went from perfectly fine to this in just 4 days.

Damaged leafs
Hi guys! I have a flowering Northern Light with several damaged leafs, as you can see on the pictures. Are they deficiencies of some sort? If so, what do you think can be the root cause? I use only filtered water and the RQS easy boost mixed with the soil since the beginning. TY

Strange spots in leaves, help PLEASE
Please, HELP. I don't know what's happening with these strange spots. Her growth is pretty good but I'm worried. Lights at 60cm. Nutrients, Temperature and RH are theoretically ok. I've even enriched it with worm humus a couple of times. Her sisters are really good all of them.
