Still yellowing crispy leaf edges. HELP!

robz · Feb 28, 2011

I've got some issues going on. I posted a few days ago with pics of my Chemdog and got some good advice. I have since flushed soil with tap water that sat out 24 hrs. with airstone. I have city water that has a pretty solid Ph of 7.0 I always add couple drops of Ph down to get it to 6.6-6.8 So after the flush all my girls have developed these crispy rust colored edges. They we're just transplanted about 8 days ago and have been doing ok but I've got to figure this out. I'm in FFOF soil and they've only been fed Earth juice tea once. IDK? I need some advice. Here are a few pics. My temps are no higher then 83 degrees ever. RH Is 48-52% First pic is Chemdog, Second pic is Urkle, third is Querkle, And fourth is Obama Kush close up leaf shot. All plants showing same symptoms and all different strains. Last flush 2 days ago and runoff water was Ph 6.8

from what i can see your new growth is looking fine. did the plant ever dry out? if the bottom crispy leaves bother you cut them off. plant looks like it needed a little food and u gave it. pay attention to the new growth as long as the stems are green u will be fine.

I think it might actually be a Fungus Gnat infestation. I've seen some buzzing around in the tent. I think the little Maggot fuckers are chewing on my roots. I took top layer of soil off a disposed of. Sprinkled some Diatomaceous Earth on the soil & then sprayed soil with Organocide. Then covered the topsoil with 1/4 in. Of sand. I'm not playing games with Fungus! Die Bastards!!DIE!!!

Predatory nematodes are excellent for fungus gnats.

At one time it was possible to remove the chlorine from tapwater by aeration and time, but that's not the way any longer. Most cities use clorinids, and they are much more resilient. A miniscule dose of vitamin c will knock them out of the water with no issues though. A gram will do fifty gallons.

Buy some mycorrhiza (endo not ecto) since you're using soil if you haven't already.

Wow, didn't know the nematodes took care of those buggers. To add to your point about chlorine, another easy way to get rid of it is to add some of the water conditioner that you use for freshwater aquariums to your H2O. Fish don't like chlorine and that's how you get it out of your tap water when you are filling the tank after cleaning.

Looked like potassium to me, are u getting a good humidity reading right by your plants? Good luck and post here when you figure it out.

Could be potassium also. I'm going to get some Epsom salt and start spraying too.

If you believe it is fungus gnats, go to home depot and pick up something called Mosquito Dunks, grind them up and either sprinkle on top of you medium or dissolve into you feed or water, or rez. If they are in fact fungus gnats, it Will kill them. Luck to ya buddy.

They are starving. They need food and they need it yesterday.

I'm pretty sure that ain't the case. They are in FFOF soil and have only been in their 5 gal. Pots with brand new dirt for 10 days and they have been fed Earth Juice tea once already. If anything they've been a tad over fed.

FFOF is by no means 'hot'. What did you transplanted them from? I mean if it was from a two gallon then it's not really that much soil.

To me, for plants that size you can feed the next watering after transplant if you wanted to. Also to me, it's showing all the signs of N def. Yellowing lower 'older' leaves while new growth is pale green. Yellowing leaves also show signs of necrosis. Also a sign of deficiencies.

10 days is a long time not to feed a fast growing annual. Get them a complete food and I'm sure they will turn right around for you.

Whatever you choose to do I hope it works out for ya. :party0042:

I gave them a good soaking with Saturator yesterday then a nice misting of foliar food & wow! Good call man. They are starting to green up nicely. Hungry little Whores!

robz · Mar 2, 2011

Oh yeah they did have Fungus Gnats though from the Sunshine mix I had in a couple pots. Crappy dirt!

Hey, I'm glad it turned around for ya! I can't take all the credit. There very well might have been other issues that were being worked out at the same time. Transplant shock or something else. The main thing that they are back on track.

Gnats.. They happen... A few isn't a big deal. Black cloud swarms of them is a big deal.

All soils will attract them and they seem to be around more in the spring and fall for me.

You can do a few things. I leave out yellow sticky traps. They seem to love that and it's a good place to check. If you don't have any on the card then you don't have many if any in the room. Get a few and you know something is up. If the card is black with them then you have an issue.. lol Try nematodes but they take time to work and are sort of hit and miss with me. If you can find something called Gnatrol then you're golden. It's a bacteria that kills the larva. It's hard to find cause it's a little costly and is only sold in large amounts. If you check with your local hydro shop they might have some broken up in smaller amounts for ya.

Keep that momentum going with the plants. It's odd, sometimes the plants that come back from 'issues' are the really good ones. Sort of how you feel really good 'after' being sick for a bit.
