BCN Critical XXL - Back to basics

We're returning back to basics with this single plant grow, using one of my favourite strains. The goal of this grow is to focus on the core fundamentals of soil, maximising yield with our small set up and keeping our plant healthy. - I always use paper towel method for seed germination, works well for me. Took around 4 days. - Soil is Westlands MP w/ JI, added perlite to about 50% composition. Soil choice was dependant on the lock down and is just what I can source locally. I have used it before with good results, it's a little on the hot side but it is manageable. - Transplanted to a 4L fabric pot at the end of the week, before she became root bound in the solo cup. - We start the seedling off under the HLG 135 set to 70 watts. We slowly increase wattage over the week up to max 135 watts as she gets settled in. - Watering at this point is not too complicated. PH corrected tap water, no nutes. - Slightly deformed first true leaf, possible damage from seed shell but nothing to be worried about.
