It's been five days since my beanlings were crusty, curled, cooked, and stalled. Five since the lights were lifted and like eight or so since the transplant. The healthiest have been putting out a full leaf set every two days and now are showing a start of some strong secondaries at the nodes. Hit them with another half dose of Dr Earth Root Zone 2-4-2 today (again, a thank you to
@Toaster79 for your suggestion of a frequent light nute regimen and correction of my light placement). I have two that are still struggling a little. The smallest Banana Ice Cream, which is now starting to catch up, and my second Royal Nepal Kush looks a bit anemic, which I hope I solved by moving it away from the fan. I think the new soil under the RNK had been drying out too quickly from the fan. It has tipped easily when it's leaves get a sprinkle of water on them giving me the impression the roots have not properly established themselves.
I like having the fan blowing directly on the plants because it causes thicker, more resilillient stalks that don't break easily, and to the best of my undersranding, provide them with better fluid uptake from the roots. Learned about the necessity of wind on growing vegetation when I read a paper on some troubles with trees in an Arizona(?) biodome. They had trees in the jungle zone with branches snapping off and even whole trees cracking and falling over. A lot of head banging turned into a giant facepalm when they realised they had to regrow the trees under windy conditions to increase their elasticity or they'd become brittle and incapable of carrying their own weight. So don't forget to let the air blow on your plants, they will be less likely to snap when the buds get heavy.
To me, this is a sign of a healthy, biologically rich, soil. Here's where some good probiotic nutes with molasses come into play by feeding the mycorrhizae.
