Droopy leaves on 2 of 6

Hey all.

(new pics are in a later post by me)


My plants have been awesome until like 7 days ago. I think I have the problem solved but I just wanted to get an second opinion.

I haven't changed the water for 2 months and have been using baking soda to rais the pH value. I only added more water, around 4-5 liters every 7-8 days.

Week 10: all plants are ok.
Three days later: Two of my six plants started to get a little droopy and leaves started to go a little yellowish on top.
Week 11: Those two plants are now comletely sloppy.

My theory is that the plants have been locked out from nutrients, maybe over nutrients.

I changed the water in the resivoir last night and the bottom of the resivoir was covered with this salt like residue around 1-2 mm thick.

Here is my info on setup

Hydroponics (bubbleponics)
Week 11 of vegging

I know it's a long vegging stage but I've been building my grow room wich is almost ready. Just need a few essential items. As it is now will be posted in the "grow room setup" part of the forums.

But as of my problem I hope this will fix it.

Here are some pictures:

This is week 10



This is last night (week 11)
-- Notice how the leaves are droopy

those have been veggin for 11 weeks??? and they are only that big, I def would say something's goin on..... Do you check your ph on a regular basis?

This is actually at a friends house but I do check the pH twice a day on working days (once in the morning and once in the afternoon but I trust he checks over the weekends.

Any advice?

I would make a check list with any possibilities that it could be, why type of ph meter are you using(is it calibrated right?), how much are you feeding them, what's your water temp,what type of water, whats your ppm, whats the temp, co2? Go though everything you can think of and make sure your doing it right.

* Water temp is just at room temp (no heater)

* Room temp varies from 23-27°c

* pH meter is this three drops into water and shake types and is yellowish when I finished balancing

* Been using GHE bloom/grow/micro in the amounts of 1.4 ml per liter of water (1.4/1.4/1.4) since they where new clones then two weeks ago I changed my feeding quantities to
8.4/5.6/2.8 ml/liter
last night as I said I changed the water compleatly and added 0.7/0.7/0.7 of nutrients

* I have no way of checking PPM/EC values since I don't have a tester (on the shoping list)

* No CO2

First i would get a better ph tester, you could pick up a digital one for under 50 bucks In my opinion those tests are very inaccurate, and I don't use the metric system but I think you might be underfeeding them, does your res have a pump in it? Because if it does that could be heating up your water to the point where it is doing more damage than good...

There is not a pumt in the resivoir, there is an external air pump though

But here is a little conversion

1ml = 0.034 fl.oz (us)
1L = 33.8 fl.oz (us)

1ml = 0.035 fl.oz (uk)
1L = 35.2 lf.oz (uk)

hope this helps

I was wrong, there isn't anything happening with the two plants except they are withering even more. Stems are quite strong though.
PLZ any tips or help ???? !!!! ????

Root rot is my only guess =/ How the roots looking?

Will take pctures later today of the roots of those two plants and the other for comparison.

Just took some pictures. Hope they will cast some light on the matter.

I can provide better images if someone likes.

ya i used to use a ezcloner and the stems would end up rotting all the time, so I went to straight promix, more forgiving....

Enzymes are natural and therefore environmentally friendly. Enzymes are found in our everyday lives in soda pop, bread and even in our body to help digest food without which we would starve even if we eat! Enzymes are catalysts, they speed up chemical reactions. Our proprietary enzyme production system allows us to produce a final product that is bacteria free. Why would you introduce unknown bacteria to a sterile environment?

HygroZyme has a specific gravity of nearly zero and has virtually no effect on ppm. Enzymes are specific in their function. Specific Enzymes in a growing medium can eat dead protein removing potential areas where illness can develop. Through this breakdown process plants are better able to obtain nutrients that are released by this process. More nutrients, less attacks allowing things to grow bigger stronger faster.



You might wanna try something like this...

Ok thank you very, very much.

So this is confirmed that this is root rot.

And is the "cure" these enzymes and maybe adding H2O2 to resivoir and dunk roots in bath of 10% solution and rinse well?

Not sure how severe my case is, first grow and first problems.

One last question, or request for advice ....

Should I just pull the diseased plants out and cut my losses now and kill 'em or try to salvage what's possible?
Maybe try cutting to clones or hoze the roots down ?

but what about this one.. this one stopped growing like a month ago.
