Confused... Help a girl out

[bmn77]

I am forced to switch these girls over to flowering within the next 4 days, due to time restraints in the future and I have been having pH problems and root rot. I solved the root rot and algae with some hydrogen peroxide and covering my res to prevent light problems but just found out that I shouldn't have hydrogen peroxide in me res. It has been in there for about 2 weeks.
Currently:
pH-6.3
14 gallon tote with 5 gallons h2o
2 tsp Fox Trot per gallon(last added nutes a week or 5 days ago (when I cleaned my res)
temp of water is around 72f
temp of Closet is 73f
Circulate feed 10-20 minutes a day+spray with nute water to get rest of roots
I have fans going into closet
CFL grow
There is a lot of damage that was from my pH being out of wack(too high then too low) on my lower leaves, but now that I fixed(so I thought) my pH problem, my plants are looking a lot healthier, but they are still slowly yellowing and browning higher up the plant and on new leaves.
Help!!! Suggestions?

to make life easier get hygrozyme, its like 50bucks a quart but will protect your roots against a nuclear holocaust! 75F will give you root rot, your really close rez temp wise, bhut with hygrozyme or a similar enzyme product you will be able to maintain healthy white roots aslong as you keep your temps at 72f consistantly, now as for PH, what method do you use to check? as an example my PH changes from day to day and its work staying on top of it, from here it looks like you had a serious phosphorous deficiency, please stay on top of your PH it will lock out critical nutrients no matter how much you feed 5.5-6.5 is ideal

First, I think it's great that you are checking the pH & temps. I don't think low 70's will bring root rot solely, there's more to it than that.
I don't think that you have to concern yourself with old leaf growth but if your new leaf growth is brown, things aren't going well.

I got a lot of advice from people on here and they were great. Don't let people fool you into thinking that they have a masters degree in pot horticulture... This is just gardening man/woman... That's it.
It's not that hard.

I see you have a 14 gallon tank with 5 gallons in it for a decent number of plants. You should up it to a good 7 gallons and don't worry about keeping the top roots & rockwool cube saturated at all times. I go in there once a day and hit them with a turkey baster from the res and they're fat.
I don't use a pH or PPM or flux capacitor reading, and they're fat.
The H2O2 that's been in there along with other junk for 2 WEEKS ? GET IT THE F___K OUT OF THERE.
Clean the res, start with fresh water & nutes and go from there. If you're in doubt, there's an 8 step recovery process that's been posted a million times. It's a fancy way of saying: "Start from scratch".

I do this every 7 days and if you check out my pics, though I haven't posted any in over a week, they are thick & bushy.

Keeping the res clean with fresh nutrients is the key. Now, it does get a bit more expensive, but on my end I re-use the nutes outside on the lush vegetation that the previous owner of my home left for me. But really, at the end of the cycle, spending another $50-$100 for top nutes is truly worth it. Think about what that $50-$100 will buy on the street... Just about nothing.

So, flush those old nutes, fallen/broken root pieces, old H20@ and sediment OUT of that tub and start over. Just thinking about what the tub must look like is making me ill. (Just trying to stress a point, not hurt your feelings).

Are you using a bubbler/air stone setup ? If so, I don't think the 'mixing of the nutes' is necessary. Do you use a cauldron ? LOL... Just kidding.

All the time, money and more time people spend on keeping that initial res nute solution optimal is beyond me.

When in doubt, flush & change.

Cheers & I hope this helped without offending anyone. And if it did... so be it.

heres how to help you out, get new clones, get an hps, build a flood and drain setup, read al b fucts threads.

flush your plants with PH'd RO water...

 

[YungMune]

ohyea...your 2 tsp a gallon is quite much i would lower it to a qaurter a gallon...but first i would flush with nothing but ph drinking water

 

[morrisgreenberg]

RAUL DUKE!!!!! the great san fransisco acid wave of 65' !!!!!!!!!!!!

 

[bmn77]

Thanks for all of the help, I appreciate it. O, and btw I do have an air stone. I changed the Res out today, added 7 gallons of 6.3 pH water and 2 teaspoons of foxfarm. Is this going to be enough nutrients??

First, lower your PH to between 5.3 & 5.8. This is where the plants have the best nutrient take-up.

On the dosage ... Most nutrients call for 5ml per gallon ... that would be one teaspoon. However, when you are growing from seedlings or young rooted cuttings, you'll need to use very little nutrients ... like 1/4 dosage.

As other's have said ... you need more light as well for best results. You can see by your first picture ... the one on the left ... that you are growing some stringy plants. That's a sign of the plant seeking out what little light is available.

The browning of the leaves is due to nutrient lock-out because of your PH being too high. Also could be from nutrient burn, although the leaf tips look pretty good.

This "hobby" is about learning what to do ... and what not to do. We've all been there where we've burned our plants, we've overwatered them, we've under watered them. But ... with persistence, we've learned not only how to get the plants to survive ... but to THRIVE. You'll get there too. Hang in there ...

I have one that I've been trying to save for 2 weeks now that looks like that (yellow leaves, red stalks). The Ph dorpped to 4 1/2 to 5 for about 5 days before I noticed. I've been watering it by hand, and flushing it every other day. The roots are finally starting to show some new white tips, but I don't have plans for taking it to fruition. It's probably taken too much shock. I might try to clone the top if it starts looking healthy, as an experament to save future f#@k ups.

to many nutrients..ur ph should b a 6.8 to 7.2 i think proabably sprayin ur plant was all bad for it to i tried sprayin my plants and the leaves got heat burns from the water heating up on the leaf
