Calcium excess.. Check your local water report.. See how much calcium you have in your water to begin with.. Use cal-mag more sparingly..

Are rust spots a concern for harvest?
Hi! Rust spots appearing on fan leaves - Week 9 Autoflower - 5th week of flower. I'm hesitant to add anything to the soil so close to harvest. I'm using Gaia Green Organic dry amendments. Is this normal and part of 'fade' process? Will this damage yield or potency? 6.3PH

Light markings on new leaves.
I'm on day 9 from putting the seed into a paper towel. Day 7 from putting it in soil. Day 5/6 from seedling sprouting. Looking closely there are markings on the leaves, what are they and should I be worried? Is the little girl stressed? Also is developing slowly?

Defoliation of Fan leaves. The COBRA's growth structure is very tight nodes with large, Indica-type fan leaves. The largest one (3rd pic) has tripled in size from the last photo. I have been bending the leaves under side-branches. Can or should I cut them off to allow light in?

Spots of concern on leaves, any advice?
Spots on leaves showed up, just a few leaves not all. Seems to be around the nodes where I fim'ed her at week 5. Other strain in the room is not affected. Any thoughts? I use a spout pitcher to feed them, I originally thought it was nute burn. Blue Cookies Fem.

Few of the older leaves have started going yellow with brown spots and shriveling up. I'm in week 7, week 3 of flower. I've been alternating nutes with Plain ph'd water, so only been adding nutes every 2nd water. Have now changed to every water. Is this just due to flowering? Ta

Nute burn or light stress
Wondering if I’m pushing them too much or if the brown rust spots are from light stress? Seems to only be on the top half of them and showed up right when the stretch slowed/stopped.

Generally not one to encounter an issue in life and immediately ask for a personalised answer, but having trawled through the various websites and found explanations for this sort of thing from 'nothing to worry about' to mites and everything in between, I've gotta ask!

Nutrient deficiency?
Hi everyone, I am a first time grower and my plants have been put into flower 10 days ago. I was just curious if the odd coloration of the new growth of leaves is a result of some type of nutrient deficiency or excess, or if it’s just the gene expression of the strain im growing.
