Is this Cal/Mag deficiency happening?
CaptStinkNugstarted grow question a year ago
The taller of the 2 Strawberry Bananas I think is showing some Cal/Mag deficiency so I added 1tsp per gallon when watering. There is only seven leaves exhibiting this on the plant and no other plants have this and everything has been the same for all plants so curious whats up?

No it is phosphorus deficiency and showing potassium deficiency from discoloration. You are not providing enough for flowering. Flowering npk ratio is 1-2-3.

Leaves light-green? Give more nutrients?What do you guys think of the leaves on this plant? She's about 2.5 weeks old in DWC. The newer leaves are looking a little light green in color, especially when compared to my GSC. Should I provide more nutes?
You can compare the lighter leaves to the darker set lower on her.Week 2

Thoughts about light green leaves subtle light spots?Leaves are consistantly light green in color. 3 week old plant, upped nutrient strength to 420ppm a few days ago.
There are lighter spots on a few leaves, one is by my thumb in this photo. Others are visible. Does this look like a deficiency? pH is 6.
Thanks all for your help!Leaves. Color - Pale

Leaves "praying" after lowering the lampI am in week 4th of flowering Laughing Buddha, 220W LED ~60cm from tops. Today I have lowered the lamp and the leaves started "praying", on one (higher) plant the other, mostly-indica Holy Punch seems unaffected. I am curious, is there too much light or sweet spot and it's good?Leaves. Other

Should I cut the first leaves to maximize the growHello everyone
A friend told my that I should cut the first leaves of my plants (the first that came out from the plants, not the cotyledons)
What do you think about this idea ?
And can this really maximize the size of the future buds ?
Thank you for your responses ! :)Leaves. Other

Twisting leaves?The leaves on Blueberry #1 (top right) are starting to twist a bit. Should I be worried? The only changes I've made recently are: 1) increasing light up to full wattage and 2) adding second fan (lower left) to add more air circulation.Week 2
