Leaf issues on my 4th grow

3x3x6

Would like to be around 300

The 350r refurb is $340 right now, with the dude code, that’s right there. They come plug and play ready. I went from a smaller Diablo 200 to the 350r and it was dang worth it. It’s a little more than a 3x3 needs, but would absolutely smash

Looking back at yours, did you use humidity domes at first? I’ve had several grows where my rh is low, so when I remove the domes, the plants get dry real quick and the outer parts of the leaves will get a tad crisp.

I had domes on for the 1st week or so

Word. I think your low rh may have some play in the dried outer parts of the leaves. The splotches on the first leaves of the pic I posted are from the rh in the dome, then going into 35% rh. They’ll get crispy soon.

Also, check out the DIY kits on HLG. They have a 320 kit that would run perfect in a 3x3. The 350r would be a little overkill.

Looks like the 320 kit may be a bit much for the 3x3. Maybe the one below is better.

No worries man! You’ll probably get it by Wednesday! They ship real quick. Just be mindful of PAR and your temps going to a higher intensity light. You’re gonna love it and so are the plants!

You’re dealing with VPD issues. Humidity is way too low, so plants can’t properly breathe and transpire. Raising levels will straighten them out again.

Thanks. I’ll look to get them bumped up

Too low and it sucks water from the leaves down to the roots, reverses the osmatic pressure.

Too high and the plants can’t breathe because the stomata’s can’t open.

I just took a 12”x12” baking dish, filled it with water and put a wash cloth over it. Wash cloth is saturated. Hopefully it bumps it up. Currently it’s 34%

Hang a towel up with the bottom tip in the water. It’ll act like a wick, and lift the water up off the floor to be dispersed by your air flow fan

Is water de-chlorinated :thinking:?

I fill 1 gallon jugs with tap water and then leave them out for several days before I use them.

Current pics. 1st one looks good. Should I top soon?


2nd one looks cooked. Should I toss her?
