attaching pics, I have had a few years of successful grows, rarely run into problems but I'm not sure what this is. i amended some raised bed "organic" MG soil from home depot with 40% perlite and dolomite lime, transplanted from the solo cup with seed starting mix and haven't fed it, barely watered it in, transplant went really smooth. i have had tip burn before but never white like this. using a spiderfarmer se3000 light at 26" above canopy at 60% power par reads around 350 on the photon app and dli is 26.5. temps are always 68-77 degress F and humidity does swing from 27% to 60% depending on if i slack refilling the humidifier. looking worse every couple hours. should i just leave her alone and see what happens? i also topped her once 3 days ago, didn't appear to stress her out much. i usually go crazy with topping and LST. advice would be appreciated greatly I'll post more pics if needed. thanks again. one pic with the grow light on and one with it off.

how fast does the humidity change when the humidifer dies?

Lock out. Pale leaf.
You “ amended “ ( lime ) into a already charged mix .
Miracle Grow have controlled release nutes that feeds at EVERY watering. Sometimes too hot for some strains.
Thinking you pushed it into an alkaline heavy issue , interfering with uptake ( excess lime ). I’m thinking it would already have some buffering mixed in , so any excess would bring problems. Miracle Grow is used by some growers but easier to have a base medium that can be adjusted to plant growth stage - like when it moves to bloom stage.

There are better “ bagged medium “ available.

Some “ retail “ like MC have coated or pellet fertilizer that will burn some plants. I use that on mostly ornamental plants instead of consumables.

thank you, I had a gut feeling that maybe the problem. I tend to over research and thought that the NPK ratios on the back of the bag being under .1 meant that the soil had almost no nutes in it, maybe enough for a few weeks. Never done this before but i just cut a circle around rhe pkant with a serrated knife, popped her out and potted her down, back into seed starting mix that i moistened a tad. then watered in with 6.5 plain water. I shouldn't have changed so much this grow, hindsight is 20/20.
i never added lime before either but decided it would help keep my soil neutral later in flower.
i usually use happy frog soil, as well. i just wasted so much time if she doesn't bounce back. I'm a landscaper, so I've seen some plants come back from some crazy stuff. stay positive, right?!
thanks again, and sorry for the long reply
thanks, I do usually use happy frog w/ perlite and i guess I was getting too cocky with my growing

No worries - easy to adapt changes in future grows.
