Into week 3. leaves curling down getting dry

[mkono87]

My girfriend is trying out autos. Here first grow with photos resulted in all males and this one is not off to a good start. Growing in straight happy frog and then planned for power bloom 2-8-4 in the later weeks. Week 3 now and they are curling down and looking dry. Looks like the plants are taking nutes from the leaves. Her tap water ph is 7.1, I did get her a cheap meter but she doesnt use it. At first I was thinking light was too close and I raised it a little bit. Also made sure there was no direct wind on the plants. She is fighting hard to keep RH above 50% but her temps are fine, around 75. Any kinda of help would be really appreciated. The only experience I have is my first grow that is a few weeks away from harvest.

- No nutes added at all yet? They look to be underfed, more than one defc. in play here,... All soils are suspect IMO, HF a little better, but for sure I'd buy a good soil pH probe (Accurate 8 is one, love mine!)... that cheap meter is garbage, take it back for a refund!
The soil is not enough, and not balanced with the right nutes very likely. Start feeding ASAP, and get that pH probe..
How far away are the lights? I see some edge curling and color fade signs that they are too close... about 24" for this stage is standard...

They were sitting at about 25" and I raised them up anyways just to be sure for now. Of course I have been searching the net its always seem to point to N toxicity but i figured they would be all dark green, and it looks like the plant is sucking nutes up from the leaves. As we have never grown autos before, all I heard is that no extra feeding is required in veg with HF but she does have power bloom 2-8-4.

The ones that curl, have a glossy look to them, almost like there a plastic film on it. If i fold the center it will stand straight up on its own.

That looks different to me like maybe a pathogen? But maybe I just have pathogens on the brain?

I’d like to know as I have the same thing going with some of mine.

And what are you growing in? Sure looks the same.

I’m growing in soil consisting of Pete Coco perlite and worm castings with Dr. earth 2-2-2 and then they have roots organics bloom

How's your temp and rh?

How's your temp and rh?

My temps are always 21 to 26. Some nights have gotten down to 20 or 19. And my humidity is always between 50 and 55. I spent a lot of time on air-conditioning and studying and I’ve got no idea what in the hell makes these plants do this after being perfectly all right for a month and a half

And now I’m noticing another problem that got a hold of some plants in last flower I had. The white hairs turn brown and shriveled back in. Here’s a picture of it happening immediately now as the white hairs come out you can see a tiny brown ones. I’m baffled as I have already presented this question to this forum about a month or two ago. and now I’m noticing another problem that got a hold of some plants in the last flower I had. The white hairs turn brown and shriveled back in. It completely ruined a Chem OG plant when it had about 4 ounces flowering.

I have to admit my RH is 48 right now. So if it is 48 most of the time, 48 to 55, is that absolutely too low for veg? Under metal halide?
