Here’s a decent article on the two:

Thanks for your reply! Light is about 40 cm away from the top of the plant. I brought it down gradually through preflower but raised it two weeks ago from 30 cm to 40 cm, because I had the same thoughts about light burn.
I´m watering with my system as i described on top, that´s the only source of water indeed. Don´t go for runoff
Hey Jack, thanks for your reply! The soils is wet between 1 and 2 cm below the surface, but then once a week I spray my mixture with the nutrients on the top soil, so it also gets some moisture directly from the top every now and then. I apply the nutrient water mix always about an hour before the lights go off, to allow it to soak in a bit. This is pretty much the only way I watered throughout my grow, once the seedling had the first tripplet leafs.
I don´t do runoff nah, because for one, i cannot assess it yet without my ph scale, secondly I am extremely paranoid about overwatering
Thanks for the info! Yes indeed I´m aware that I don´t have quite enough ventilation there. The tent is not really an enclosed environment, and the led luckily has it´s own (actually computer) fan which does create some movement. I also open the door a couple times a day for 15 minutes or so, to bring down temp and refresh the air. Planning on the carbon filter though for the second round, that should do the job.
You can still test your medium’s pH using a slurry test.
Honestly, w/o the proper measuring devices so you can fine-tune your environment, your plants are probably suffering from high heat, low humidity, poor air circulation, and pH issues.

Gotcha. That’s what I guessed. So what you’ve got is an over fed plant. It definitely looks overfed, I just wasn’t sure how it got that way.
What’s happening in your cycle is your feed is going in/on top of the soil at XXX PPMs. It goes on at XXX PPMs time after time, and since there is no off, your soil has built up salts in the upper layers or at least as far down as it’s migrated.
The purpose of feeding to 20% run off at each feed is to know that what you’re putting in is what the plant is actually eating that cycle. Right now, your plants are eating all the left over cycles and that’s why is looks overfed. I’ll bet you have about 4 more weeks. If you don’t want to learn flushing now, I would go water only right on through the rest of the grow. Should be winding down the feed now anyways.
I understand your fear of over watering, next grow you definitely want to look more into watering to run off and switch to smart pots. With cloth pots and Pro Mix (or Coco coir), you could dump 15 gallons through that and not over water. Just be sure to let it dry properly, don’t water on a schedule, water when they need it.
Trust the voices here. @blackthumbbetty is absolutely right, you’ve got to have the basic tools. She’s been doing this longer than me. Get a pH meter, a PPM meter and a small fan…first step, low cost fixes that will go a long way in your size tent.
Meet a plant from my first grow. She was in a plastic pot that I didn’t run off. I fried it LOL. She was harsh!

damn this is 100% exactly what happened. Thanks a lot for your message! Yep these are exactly the improvements for my second session.
At this point I had to cut off all the crispy leafs, which was about 80% of all leafs by now. I made sure to only cut super crispy, totally dry ones. The buds didn´t grow gigantically but it´s quite frosty now and most of the hairs turned amber. I will leave it in soil like that for another week or two, give it occasionally the flushy type of watering and no nutrients. Then maybe one or two days of darkness and then it´ll be time for the final cut.
Im still really happy that i will finally have some product and yeah, just really excited to see how it´ll hit.
Thanks again to everyone helping out here!
