Any suggestions on what’s happening with this plant? After a few bumpy weeks treating thrips and getting the soil pH adjusted to 6.5, my Jack 47 plant produced new growth that appears like this. I’ve supplemented with Cal/Mag and flushed the roots. Feedback is welcome.

Should I remove some of the dense foliage as I start LST, or wait? Other suggestions appreciated!The Durban Poison and Jack 47 are very dense, with tight nodes. I’m beginning LST this week to get more light to more of the branches, but should I prune some of the excess foliage? If so, how do I decide what to remove? Thanks in advance for your help!

Does this look like minor leaf burn, too many nutrients or something else?I believe two of the plants developed minor leaf burn. One has white streaks on the middle and outer portions of several leaves, and the other has a rust, reddish stripe parallel to the center of several leaves. I’ve attached pictures above. Thoughts are greatly appreciated.

Is growth normally this slow for seedlings? Any advice appreciated.These 3 seeds (of 12) germinated March 19-21; I transferred them to coco coir/perlite soil under 40W full-spectrum grow lights I also use for garden vegetable seedlings. Lights are on 16 hours; off 8 hours, and the seedlings have barely grown in the last 10 days. Is this normal?
