Hey tick tock,
So anytime i got those rusty splotches it ended up being lack of a calmag supplement or i had a ph problem once that reeked havoc. Since your ph # is good, unless you want to recalibrate just to check, look into a calcium/phosphorus issue. Maybe drop your bio grow and pick up the bio bizz calmag supplement and the problem will probably sort itself out. Unfortunately the damage is usual permanent but you can stop the spread and make it through flowering. You could possibly up the bloom nutrient for a higher phosphorus level since purple is often caused by that...but being in the mix already I'd lean more towards a small calmag dose each week.
Happy harvesting. ✌️

I believe when this happens you can give them a light compost tea when the roots dry out and raise the lights, let them chill hopefully in low temps. I call this putting them in the infirmary. When they recover give them just water until they grow fast hen give them 600 ppm nutrients or an organic amendment.

Your plants are a bit high on nitrogen hence the nutes burn and dark color of the other leafs
The rusty purplish leafs are a sign of phosphorus or potassium..not really sure witch it is..but treatment stays the same..first flush out old nutrients and the last flush you give halve a dose bloom nutrients (cut back n and add something like pk 13-14 a bit more) let her dry out and then you fill your pot back with full dose nutrients
✌️Happy growing and stay safe 🌱

Hello.. Hope you are well.. It looks like a case of overfeeding and deficiency.. 1)Give her a complete flush thru at ph6.2 if in soil.. This will help get any nasties out surrounding her roots.. 2)give her nxt feed at ur normal dose minus 20% of nutes then slowly bring her bk.. 3)if u dont mind then use a root stim to help any damage.. 4)take off damaged leaves only wen u see signs of improvement (unless they totally crispy).. Stay safe n gud luck.. 👍🍀

Hey my friend :-) This can be genetic, but it can also be that your temperature is a bit cooler, since some strains tend to stain, which is not a problem as long as you don't get far below 18 degrees Celsius :-). I would watch something. Let it grow, it looks wonderful from 👍🌱🍀

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared.
Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.

N or P deficiency?Need help to understand if this is P or N deficiency. It's on the lowest fan leaves, one is more pronounced than the other, and it's mostly on one side. Stems and veins look like they're giving hints of P def but from what I searched leaves look like it could be N def.

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Catching a fade?Is this fade normal for a Crème de la Chem? Or is this some other kind of deficiency. This plant has not had any issues. She’s the most healthy of all of them. In the pics I’m trying to illustrate the purple color showing up on some leaves.

Nutrient imbalance or healthy development?Are the colors of the leaves a sign of healthy development in the flowering stage, or a sign of nutrient deficiency/excess? After struggling a lot with the nutrition of this plant, I am not sure anymore whether I'm doing it right. Some of the leaves become yellow and fall off.
