Fan Leaves yellowing and browning 3 wks into flowering

[DreadedHermie]

...this root ball looks healthy and normal to me... What do you all think?

Yep...normal, healthy, and rootbound.

Light flush, then transplant up 1 container size. If you leave them like this much longer it may be difficult to get the roots to explore the new medium when you do transplant.

Regularly means whenever I see any sign of mites or every 3-4 weeks as a preventative. What kind of negative impact are you concerned about?

coating or clogging the leaves?...maybe, increasing the heat on the leaves?

I think you probably have some kind of nute lockout. What kind?...I don't know...sorry. Most of the 'White' strains do have leaves that turn yellow very early. Usually they start at bottom and work up...very slowly, though.

Well, I'm going to try flushing with florakleen, adding a micro supplement (Cal-Mag) to my feedings and when they dry out in a couple days, transplanting to 5 gal. pots about 2/3-3/4 full. Am I missing anything?

Sounds good. I've used Sterilite waste baskets in a ~3 gallon size when I couldn't get proper size pots; that worked fine. Paint or light-proof tape for the translucent models; don't forget adequate drainage holes.

I'm always leery of leaving a humid pocket of dead air at the top of the pots. Bugs like that, esp. fungus gnats. If you're stuck using the 5 gal. pots, I'd put 3-5" of drainage material** in the bottom of the pot and keep the top of your rootball within an inch or so of the top of the pot--no more than necessary to accommodate your watering technique.

**(Semi-smooth river stones from Ace Hardware, ~$3 a big bag, work well. I got some near-hydro roots going into 'em last time. ) If your roots populate all the soil you can replace some of the stones with additional soil in the same container. Kind of a transplant in the same pot. I do it allatime. :thumbsup:

That's a great idea about the stones in the bottom. I wish I would've read your post before this morning, when I transplanted all of them (god my back hurts). I never thought about the space between the medium and the bottom of the foliage as a home for pests. I'll keep an eye on that. I probably have a leg up there though, as my humidity is so low this time of year only the mites come around, and I just try to take care of them preventatively. Thanks for all your help.

i just ran into a similar problem where plants being rootbound showed all kinds of deficiencies. i have since (last night) transplanted so hopefully they will start perking up.

Good luck. I'll post pictures in a couple days.

It appears that the girlies are ok after the flush and repot. I'll keep posting in the indoor growing forum, but not here unless I'm wrong (again) or have more problems.
