Yellowing clones, tips turning greyish?

Hey guys, I'm almost on day 7 with my first batch of clones. Still no visible roots. Yesterday they were showing some yellowing leaves which I thought was good, but today i noticed two of them had grey wilted tips on the leaves, one is really hard to notice.. anyways was wondering if it looks like mold? Humidity was around 85-90 first 3 days, and i wafted air in the dome 3-4 times a day. Day 3 I cracked the vents half way, and day 4 i cracked them fully, also taking dome off completely for 30 mins 2-3 times a day.. if it is mold should I throw away the ones I spot it on or is the whole tray trash?

Well there is no need to worry they looks absolutely fine i also faced such problem with my plant but a bit more sunlight and water can actually help. this is its growing period and they often shed leaves and new ones grow in that place so no need to worry. Cultivating marijuana is an art and it require proper attention. you can also take the help of this article. https://forgardening.org/plants/planting-marijuana/

I'm still at the point where I have no roots so they don't need much light yet, and overwatering can slow down the rooting process in rockwool. Also that article had nothing to do with my situation

There response was under the assumption that you're in veg. Whenever I see a sign like that that is a likely mold infection I pull them because it will quickly spread through your tray. Other than mold the only likely thing is a deficiency, either from the original mother or something like your cloning water being to far out of the ideal ph range. If it is from a deficiency then you'll end up with necrotic (dead) tissue which will end up diseased from the high humidity conditions do in either case junk the unhealthy ones.

Thank you I think I will toss it when I get a chance, is that what mold looks like? I've never seen mold like that, but it looks like it could be.

I have seen it start out that way. To be honest I'm not 100% that that is mold but even if it isn't it will be in a couple of days of being under a humidity dome.

It's starting to show on some of my other clones, does anyone think this is mold? I opened up one of the rockwool cubes and saw some root nubs, so they're pretty close to being done.. should i throw away any ones that I spot that on? Also should I take the dome off?

The alternative is to go through and cut out every single piece of leaf that looks like that. It's a good idea to take the domes off once or twice a day for long enough that the leaves can dry out to prevent this. Now that it's happening it would still help. I'd cut out the infected tissue and start pulling the dome.

Well if you thing that this is because of some mold infection then i suggest you to cut those infected leaves as it helps in stopping them spreading.

Really not sure if it's mold, is it possible that's just what they look like when they root? I've noticed the couple I trashed had started forming root nubs, i cracked open a rockwool that had no wilting on it and it had no roots.. maybe it's from the rooting powder I used? Also it always shows on the top set of leaves on the clone, haven't seen it on the bottom that's why I think it might not be mold. Like schmoejoe said though, it would prob lead to mold if I left it with high humidity, so I got the rh down to 45% now and giving them fresh air 2-3 times a day. Im on day 8 now by the way, should I just stop the dome?

With all due respects, you just got 2 answers of what others think, why don't you do what you think is the best way to go about it instead of contradicting yourself, it's called "experience" let it ride, keep them isolated and find out if it's mold or not.
