Well you should be 24-28" away with a true 300w led usually. If you fall out of that range you may be burning it. Especially considering the 24h schedule.
Perhaps even more likely is overwatering. The pot looks pretty small which makes this a real concern.
Other possibility would be nute burn. She doesn't need to much in the way of nutrients right now. An EC of 0.6-1.0 would be sufficient I guess. If you're feeding based on the nutrient bottle recommendation, this burn is likely, especially if the soil has time release nutrients already.
This should help. As with any issue, always start with a pH check.

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.
