Please help. What's happening? Pics included

[Illicitmango]

I have given them a little bit of super Thrive as well. They're getting worse and I'm afraid to feed them based on the way they look . I don't want to burn them .
Would it help if I just transplanted them with new Soil and Water them with RO water?

 

[Roger A. Shrubber]

i would, they look like they're about ready for a transplant anyway. get some soil with no sawdust or chunks of wood in it, add 25-30% perlite to it, and if you have any garden lime, a couple of tsp thrown in the mix will slow down how often you have to add cal-mag

 

[Illicitmango]

Alright . Will do . I'm gonna stop at home depot or Lowe's on my way home from work . there are no hydro stores nearby. Is there any brand of soil you would recommend that either of those 2 stores carry ? Thank you so much for the help btw.

 

[Roger A. Shrubber]

np.
not sure what they carry, i usually go with a potting mix and add my own perlite and lime, maybe a little peat moss.
just try to find something with no big chunks of stuff in it. its ok if you can't find anything without some nutes built into it, just remember to take them into account

Here's some more pictures . I cut off the dead stuff . I replanted them with fresh soil and watered with RO water .
A lot of the older fan leaves were all curled up and crunchy and brown.
Any input would be greatly appreciated as to what seems to be happening. .

Ph issue imo ,probably too much feed. I'd use all-mix (pro-mix in u.s.) or something similar. What soil did you transplant into ? Good luck + happy growing

I just repotted them with the same kind of soil I just used fresh soil from the bag because I have a feeling that the soil that they were in became too acidic from what I was trying to feed them. originally I was just using tap water but I never had a pH meter or anything. So maybe when I fed them it made the pH go all out of whack?

 

[Illicitmango]

The problem seems to still be there . I'm lost . if the problems were fixed, how long would it take to clean up? And can these damaged leaves ever recover?

 

[Roger A. Shrubber]

damaged leaves never recover. you repotted yesterday. give it a day or two.
let some new growth come in, if it looks good, then relax.
GET A PH METER.
dunno what your tap water comes out at, but mine comes out at about 7.2...too high, by far.
if you aren't in the proper ph range ( 6.2-6.8 ) you will be locking out some nutrients.
its a good idea to slowly swing through the range, phosphorous, cal and mag can't be absorbed below 6.4 in soil, if you stay too high too long, you get problems with manganese and iron.

 

[Illicitmango]

Alright I'll try to relax a little bit and see what happens. I had a grow back in March and I harvested early July and I didn't really have any problems other than I was over watering. Now with this grow I'm doing everything pretty much the same but everything seems to be way different.
But back to my actual problem the black and brownish spots on the leaves seems to be increasing...or getting bigger .

if you dont have funds for a pH pen see if you can get a pH test kit in pet section of department store or home improvement store. It is a temporary fix until you can get better. Cant really get runoff with it if already discolored but for watering your plants at least you KNOW what you are putting into them and they cost like $5 give or take a buck or 2 and usually come with the pH Up and pH down included. Like I said, it's a temporary fix until can get better stuff, but at least you gonna have idea what pH water you watering with

***edit*** just to be clear,,Im not suggesting one of those pH soil test kits....it's for use with aquariums usually

Fungus gnats?! I found some gnats flying around and a couple in the soil . . .
Are these little buggers causing all this damage ?
What's the best way to kill em?
Thank you guys

 

[vaporz]

soil probably had them in it when you bought it, the fungus gnat larvae can feed on roots if an infestation and lead to a whole bunch of issues like root rot, make some fungal problems.

they really like an overwatered soil too, if overwatering you bound to have fungus gnats

You should bookmark that site if you havent already. I noticed another member posted some links to this site a few posts ago. It is a pretty nice site with some pretty useful info.....between this forum and help from other members and the information on that site you can just about figure out plant ailments most of the time....very valuable source of information to have if members arent around to help diagnose or offer suggestions.
