Just new sites forming for flowering phase. Nothing to worry about. Those larger leaves are known as 'fan leaves"

Zu viel Dünger benutzt?????
Pflanzen hab ich glaub ich überdüngt sollte ich bis zum drain warten mit nur Wasser giessen um den Überschuss in Griff zu bekommen oder direkt reagieren und spülen??? Erkennbar an den Blätter rändern, die Zähne klappen sich hoch, oder bin ich falsch?

Yellow edges
I had just dealt with a calmag deficiency but adding biobizz calmag, but now the leaves are starting to yellow on the edges. Is it still a calcium or magnesium problem, or is it something else?

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?

A number of lower fan leaves have started to yellow and die on both plants. I have increased FloraMicro dosage but it doesn't seem to have helped. Is this something other than an N deficiency? I think it is too early for the plant to be scavenging resources from the fan leaves.

First grow with autos, are these growing too slowly after a week?
It's the start of day 7 and compared to some other posts, I worry these may be smaller than what they should be after a week. Are growing slower than they should be, and is the discoloration on the 2nd image a cause for concern?

Nutrient deficiency??
I am struggling to find out what my plants are lacking or what I am overdoing here, can someone please help diagnose what this brown spots are on leaves? My guess was boron deficiency I’m worried if I don’t fix it quick it will kill the crop :(

Hi all, 2 northern lights and 1 bcn critical seedlings are showing signs what I thought might be thrips, but I haven’t been able to see any bugs yet. I put blue and yellow sticky traps and still haven’t seen any bugs. Any ideas on if it’s worth worrying about and how to fix.Thanx

Odd looking leaves
My plant showed true leaves finally but looks odd Could anyone confirm if it is not OK? If not, is this something that could be fixed or it is just bad luck with the seed?

So, tiny rust spots on upper fan leaves (please see pic above-week 8). Is this a Calcium/Magnesium issue or something else? I’ve been weaning these ladies off the CalMag over the past 2 weeks and then this showed up. It’s also been very cold in my tent so I’m not sure. Anyone? 😱

Nutrition lockout?
What’s wrong with these plants? It’s the first 4 in the video that you see. Rusty spots. It’s not a fungus. Some lower Leaf tacoing, runoff PH low but have been doing nothing but filtered water at 6.5. For over a week now. Soil grow, end week 4 of flower. Looking small for SLHaut

From the end of last week all the plants started showing problems, this one got yellow on lower leaves with brown stains or spots, see the picture. Could it be RH related?

Leaf colour and buds
Are the leaves still too dark and should I be flushing more? Just worried I've ruined the growth with the overfeeding of nutes now 😓. It seems small but I guess there's still few more weeks to go? Also for nest time am I supposed to remove the lower smaller buds? Thanks 🌈
