1st grow Blackberry Kush & Daiquiri Lime

I've transplanted them to the big pots on day 8. Since then they are staying in a greenhouse during the nights and I usually take them out when the weather is nice (it gets very hot in the greenhouse when the sun's out). The soil is a generic gardening soil with some (may 20%) home made compost, some horse manure granules (not much, maybe 300g for both pots), some wood ash (as I've read it's a good fertilizer), also not much really. I've also added some lime to raise the Ph, as I've read the wood ash brings it down... But I have no means to reliably measure it, so I just added "some". Didn't add any perlite to the mix, as I wasn't really planning to get any supplies in advance and just used what was around the house. I hope it will be fine... On day ~11 I've watered them with a tea from stinging nettle, dandelion, and a few other herbs I found growing around :) I saw a similar thing on a different grow around the site. I just poured hot water over the herbs and let it sit till next day. Shouldn't be hot on nutrients since it didn't really ferment but should extract the minerals from the plants. I've diluted it like 4:1 for the watering. Didn't observe any noticeable effect. Now the seedlings started mostly being the same color but really differentiated after a few days. The Kush has a nice deep green while Daiquiri Lime stays true to it's name. At first I thought it's the strain, but then I looked at other people's pictures and it had mostly normal green color. Its also growing slow, especially since the transplant. The night temperatures were also quite low in the greenhouse (around 5C some nights), so that might have been a factor, but the weather got warmer about midway into week 2. And, its growing asymmetric leaves. Perhaps its nute burn? Maybe there was a pocket in the germinating soil with high content of the horse fertilizer... Dunno. I'm waiting for it to snap out of it... Not much else I can do I think.
