Auto flower deficiency
Hello I have a auto flower I grew in soil from last year. I believe this is a nitrogen deficiency but not sure. This plant is 37 days old and 1 week into flower. How can I fix this? Cal-mag? Worm poo? I'm not sure.

What's Happening to my Glookies? Lower Growth Yellowing with Grey/Light Brown Spots.
Yellowing with grey/light brown spots occurring on the Glookies plants (starting from the tip of the leaf). I believe it may be due to the Fox Farm Ocean Forest soil mix but any advice or input on what is possibly happening is greatly appreciated. Fingers also fused together.

General health
Advice please just on wether it's looking healthy. :) I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

Autogrowing
Auto flowering, PH is 5.8 to 6.1 every day. Hydro set up. Botanicare grow, calmag, and hydroguard all given half the regular amount.
Finishing up second transition week. The bottom leaves started turning a little yellow but are now turning a lot more yellow. Assuming this is the plant just using it's own nutrients stored in the lower leaves. Any input? It's a hydro set up. Thank you everyone.

I noticed that the lower 2 leaves are yellowing and I think that are a little crispy. I topped the plant at the beginning of the week ago and I removed the first pair of leaves three days later ( yesterday). Do you think is this a problem? What can I do? Thank you. Peace
