Quick diagonisis please???

[home.grower]

Check my plant pics here and let me know if u can diagnose the nute deficiency please anyone...

All details about grow techniques are in the thread, but feel free to ask me questions to help me solve the problems in the images linked here.....

My first Flood and Drain attempt Please help Me (http://boards.cannabis.com/1510610-post61.html)

I think your temperature is too high to begin with- see the upwards curl?
And that can easily complicate a nutrient problem.
Does your medium dry out completely between flood cycles, or stay a bit moist?

Could it be that my reservoir temp is too high? I have an aquarium heater in it on its lowest setting....

I don't know why I'd have a temp problem in the garden. I have the lights on during the night.

I've noticed that the burn discoloration is visible on plants that are not in the hydro system (there are other potted plants of similar strain also in the room).

Errrr, the medium is a 1inch rockwool cube and pebbles. the floods a 2 or 3 hours apart. and yes all seems pretty dry between floods.

I've had the Dr in and spider mites and other tiny bugs are visible on some of the leaf undersides. I will try and take a close up pic shortly.

Hope the additional info helps stinky and thanks for ur gro support :)

I've looked, but prefer to communicate with someone to ensure I'm looking at the situation right... Thanks for ur comment

Any Help??

Okey dokey, I'm not the hydro guru here but reservoir temps are important. I'd scoot over to 'hydro' and poke around to see what others are running their res at. I know that reservoir COOLING is quite common. Personally I would ditch the aquarium heater entirely if you find that your room temp is acceptable. The only time I would heat a res is if it is sitting on a very cold concrete floor, or your air temps stay too low at 'night'.

So what is your maximum sustained temp during lights on?
And your minimum at 'night'? (the difference between these is important)

And the bugs... time to bomb. Try the Raid pyrethroid bomb. Set one off, wait 3 days, set another off to kill stragglers, then mist leaves lightly with neem to prevent reinfestation.

Also, what type of pebbles are you using? Hydroton? With the 1-inch cubes in hydroton, you may very well be drying out TOO much between floods. Why don't you try adding another flood cycle to your 'lights on' time?

[rhizome]

I heat a res if under 67F, and cool if over 73F.

But I'm kinda anal:D

[stinkyattic]

So rhizome, looking at the temps that most people are running indoors in summertime, you would certainly be cooling?

[rhizome]

Well, most aquarium heaters have a little thermoswitch built in, so I doubt he's actually heating- heater won't kick on in a warm res.

Evap cooling will generally keep res a few degrees cooler than ambient.

I'd prob be cooling the room enough to keep res ~70F-, but if that wasn't an option, then yeah, I'd be cooling the res.

Grab a floating thermometer from the pet store and drop it into the res- easy enough to know for sure.

I just clicked on the link and got some photos but no information......

Ok, I found the right link. Home you got too many threads hopping around. Stinky and Rhyzome are right about the water issue but you mentioned in your other thread that your e.c. got up to 2.2 one day.....I think you burned them at that point and what you are seeing may be the end result of that. There were too many posts for me to figure out exactly about your lighting and feeding schedule.....you don't measure ppms' I assume....just ec?

28C Max daytime 20C Min nighttime

I will have to use the bug bomb because I'm looking closely at one of those pix of the underside of the leaves and I can see lots of tiny black dots.

I now think, with the help of everyone, that I have a combination of problems.

1. Bugs
2. Over fert

for sure. And Yes I am using Hydroton clay

Cheers

I don't have a thermometer for my rez atm, i shall invest in one... I will remove it as stinky said, but the reason I added it was because I put my hand in and thought it was cold... maye it was ok all along?

I have only started a few threads. As I was uncertain as to how many people read my Grow thread so I wasn't sure if I'd have gotten the help I needed without starting a 2nd and 3rd thread... I'll try and keep the thread starting to a minimum.

That's right. The EC had worked its way up to 2.2 at one point.. I remedied it by partial flush if I recall correctly... It could have been a ful flush, I'll have to check my diary.... So I'm now seeing the after effects? Makes sense... the deep deep green leaves and tip burn that spreaded is a tell tail sign of over nute...

I'm still flushing...

So what about the bugs? Would the bugs have caused the leaves to look like that aslo? I don't have any magnification equipment so I'm a little stuck there..

And if anyone can further comment on my brown roots, that too would be welcomed..

cheers

I've just looked back through my Gro diary and can confirm that on the 26th June I found the readings off the scale...

pH/EC=6.5/2.2

Resolved with partial reservoir flush and topped off with water. Resultant readings...

pH/EC=1.5/5.7

But after running the system to check all was working, I accidentally left the res pump off for 2 days before noticing...

I've been runing with pH'd water since 28/06

[Weedhound]

And what are your general numbers now day to day? I've burned my plants (say not so :)) and the ph will usually tell me where I am at with that process....it will rise, stay high for a while, then slowly start to return to normal as the plants recover... (yep, done it more than once too :D) That strikes me as more logical than heat because your burns are very uniform on all your leaves.

As for your insect problems I'm very VERY sure Rhizome and Stinky can answer your q's on that better than I can.

Good luck.
