Hey guys, I noticed a little mutation on my Sunset Sherbert seedling it sprouted with three cotyledons instead of two. Will this cause any issues later on with its growth or genetics?

First flowering? - is it the right time? Also, 'claws' on the tip freshest leaves
Is this a first flower on BPP? I have no idea when to start with Bloom/Topmax, is this the right moment for this plant? Also, you can see the little 'claws' at the tip of freshest leaves, just on top. Is this caused by putting the light source too close? It was 40cm,now 47/18,5

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

Fan leaf finger progression
I read somewhere that a healthy plant should increase fingers with each set of leaves. Wendy had two 3 fingered leaves, one of which wasn’t clearly defined. The next set of leaves look to have one with 4 fingers and one with 3. Should I be worried? Does she look healthy?

Scharze und braune Flecken auf den Blättern
Es ist die Watermelon Auto. Ich habe heute einen Bud mit Schimmel entdeckt und entfernt. Ist das ein Pilz in den Blättern oder nur Calicium- / Kalium-Mangel? Es sind zum Glück nur wenige Blätter betroffen.
