Calcium deficiency. Add some Cal/Mag to your fertilizer line up, or if using it already, increase the dosage. Affected leaves won't recover, but new growth should mainly be fine once this is done.

Under-watering? I water all my plants equally and one seems to be growing steadily and two have stopped. How often should I be watering in smart pots and how much water should I be using each time? Also is there anyway to save my two heat damaged plants or should I scrap them?

I came back to my plant today and noticed issues with a bunch of the older leaves. Is this calcium excess?

I'm seeing some discoloration, and it's spreading to the newer growth. I have been watering at pH 6.5, but upped water to completely soak the medium. How much should I let it dry out between waterings? Organic dry amendments, mycorrhizae, and CalMag.

Need help diagnosing leaf loss issues with the G13 Haze strain (problem has been over 5 weeks now). The one in the smallest pot (7L) has lost a majority of its leaves. The leaves start yellowing and turning brown then crispy. They have white speckles on them like salt.

The leaves on my #1 look wilted or old...you gotta look to see what I mean lol. Can anyone explain whats happening or why they may look that way? Both have been given the exact same treatment in terms of nutes, light height etc. Both popped at the same time. 9 days old.

In week 12 of the diary I show the continued issue with yellowing and loss of leaves. One G13 plant has nearly lost all its leaves. I think I have a pest issue, see week 11 diary picture of the pot with lots of white tiny things crawling. Could this be root aphids?

I believe I fixed my nute lockout a couple of weeks ago. But since flowering has started I’ve been getting a deficiency on the older leaves from the bottom moving to the top. I’m wondering if this is A nitrogen deficiency as I’ve backed off on the nitrogen since I’ve switched to flowering nutes. I’m not really sure how to proceed or if I’m even right.

One of my 3 plants is significantly smaller than the other 2. Her leaves are multiple colours. She was late to shed her shell so I peeled it off myself. She is still steadily growing however I have been unable to diagnose her. The photos of her are labelled "sick one"

Anyone have any ideas as to what type of burn this is in the last few photos? I’ve ruled out pH issues as it’s staying steady at 6.5. Is it some sort of nutrient lockout or deficiency? Heat stress?

Reddening of leaves quite prevelent at top of plant. Think it might be a PK deficiency. Question being - is it too late to add a PK booster at this stage of flowering? [Or will I have to ride it out?] Thanks, Harry

Anybody know what’s going on with this girl? All in all, she’s growing right along with my other but some funky coloration and growth. Not sure if I should start a new one or let her go and see what happens. I appreciate any advice and input.

Does anybody know what the white tops are? Can be seen clearly on pictures 14 and 19 of week 13. I thought it might be light burn maybe, but it looks too healthy. I also noticed that they start to turn green after some days. Just being curious...

There is something wrong with my plants but I'm not sure, I hope it's nutrient burn, iun whiuchn case I will flush with PH water, but it could be nutrient deficiency, what I am most concerned about is that this is root rot. What do you think it is and what should should i do?

All my plants are infested of thrips ! I didn't notice before, beginner mistake ! I can see the thrips under the leaves, even close to the buds. I'm about to harvest 1 plant very soon and the others in the coming weeks, can I harvest anyway or I have to get rid of them before ?
