advice please

Hi these 3 seedlings are 7 days old from seed 5 days since they first broke the soil. They are the same strain auto double big bud from just feminised.

Day temp 24 to 28 night temp 21 to 23. Just on tap water with lemon juice to raise ph slightly as I have quite alkaline water. Have a gentle breeze 24 hours a day with a 19 5 light cycle under a 600w dual spectrum hps.

All seem to be going nicely but the 3rd image plant 3 lets say seems to be lagging behind a little wither thinner and less sturdy leaves. I was thinking it myt just be swaying to a more sativa phenotype or is this some form of deficiency?

be patient young patama

lol some plants just grow differently and at different rates. Toke up and relax. They look fine.

Haha I no probs nothing atall cant help but analyse every mm of growth

are they fem seeds? i noticed that on reg seeds most of my males are the fast growers.

Ye they should be feminised hope they arnt males will just have to wait and see I guess

My fan is fairly strong and have also had my tent open during the day due to hot temperatures at the moment the thinner plant is closest to the fan and was furthest from the light would this cause it to grow differently I understand one growing slower just seems to look like a different plant

well light will effect growth and the amount of wind blowing on it will effect the strengthening of the stem i would think.

Does it matter if I change the light cycle slightly just getting quite cool now and normally wouldn't be putting light on for a couple hours would a 21 3 for q day shock the plant atall. I figure it wouldn't as daylight hours vary throughout
