Calcium deficiency or PH problem?
Is this a calcium deficiency ? given the soil mixtures (recipes in germ. week) unlikely. since they only get tap water, i checked the values Ca2+ 65.6 mg/l Mg2+ 17.3mg/l that's an 3.8:1 ratio. PH is 7.6, I never checked that tbh. doesn't the soil compensate for that?

Weird leaf color/appearance
I've noticed that sporadically throughout the plant there are leaves that bend to the side and have this discoloration on half their fingers. Any idea of what deficiency or over nutrient problem this is?

Should I cut the first leaves to maximize the grow
Hello 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 ! :)

Can root damage cause this?
The little f*cker has a major damage to his taproot since germination phase. I accidently broke the tip of it. But she was very strong. Fought for her life and won the battle. Now she is 12 days old and shows this. Is this caused by the root damage or from other circumstances?

Cause of skinny new leaf fingers? Started a week ago or so but all the new leaves coming in have been had very slender/skinny fingers.. PH IS GOOD
Was doing research and what I found was either P excess, low humidity levels, light stress.. or just the Savita genetics? The plants are all in good health, growing fast and do not show any signs of deficiency aside from the skinny leaves forming. PH is fine, its living soil..

To defoilate or not to defoilate.. that is the question!
I've always heard that you shouldn't "defoilate" auto flower cannabis, especially if they're a sativa to boot. With that being said, (looking at my pics for reference) should I do more defoliation? Would doing so really increase my yield significantly? Thanks
