Auto White Widow DP coco grow

Being a second time first time grower i made the usual mistakes. I germinated with the moist paper towel method. Waited for the tap root and tossed them in the coco. In my haste i placed them 2 inches down or so. The next morning i woke up and decided that i made a mistake and all the seeds must be dug up 🙃. Yes, yes, yes i know im a dumby. Ive learned and moved on. My other issue this week was when i got my nutes i had purchased part a of ph perfect coco grow and part a of ph perfect coco bloom. Well good thingseedlings dont need much for nutes because i went to the grow shop and everything else was there except coco grow part b, im telling the shelves were stacked and there was one empty row just misaing this exact nute that i needed, ugh. I hoped for the best as i waited for them to restock. Going into week 2 with a nitrogen deficiency developing on one of the lower set of leaves on only one of the plants. Ive seen this before on my first plant. Coupled with the fact that i knew i was missing half of my nutrient soloution this was an easy issue to pin down. After the hydro shop still hadnt stocked up on my part b i just got 1 day prime shipping. So i finally fed them a full nute soloution on day 9. As I feed them I decided there needed to be more air movement. So i lowered my 12in fan to about their level 🙃 and turned it on low. I decided to check on them in the evening. The fan was far too strong this close. It pushed the closest plants leaves into the soil over and over again over the course of a few hours, damaging the tip of one leaf. That was fixed by lifting the fan up higher and letting the wind blow down the sides of the tent onto the leaves. A 6in fan would have been plenty at this stage. But the timing on this made me question the if it was the fan or nute burn. It was definitely the fan.
