HELP! Don’t know if I have a issue

[420Snoop]

Anybody can give me some tips on what’s going on I got some purple stems and slight yellowing, some leaves seem to be yellow and purple there’s a little toxicity that burn the tips but I watered about twice regular water since than
Growing autoflower “Critical Purple Kush” strain it’s at the 4 week and a half mark for flower for the big one and about 3rd for the baby under a 600w led temp stays at 80 drops to 70 when lights go out
im just going to upload a few photos of the plants and the purple light doesn’t make a difference looks the same under both regular and purple to me

The purple stems are nothing to worry about. Some plants have stems or leaves which turn purple. Some buds come out purple while others will turn purple if you get them cold enough.

I don't see any major yellowing/concerns. But this article may help you determine if any of the top 10 issues ring true

They never get to cold and I don’t know if it’s genetics the yellowing leaves are droopy also

Purple or red stems are actually a response to the light. The plant induces something to the stems to protect them from too much light.

That's definitely one possible cause of red or purple leaves. Although I suspect this grower's leaves are due to genetics (growing Purple Kush)

Here's a full list of possible causes:
