Whats the main cause for dry brittle leaves, Ive been watering only when it dries out but not leaving them with dry periods at a time. Ive also started spraying them once a day and they have a small computer fan on them blowing gently. moistures about 50% around the plants.

Dry brittle leaves usually signal fertilizer burn.

hey - any more info? like how old the plants are, whether into flowering, etc? might help...

they are 5 weeks old. the brittleness started whilst in the old pots b4 any fertz. they were then transplanted into bigger pots. now even the smaller one that wasnt suffering from being root round/low fert is getting brittle!

I'm back and after reading through your journal here's what I've come up with,just hope we don't catch sh#t for double posting,but I understand where your coming from,anyway here goes :

• I agree with Choader on the chicken manure, bit heavy, he has alot of good advice in his post too.
• The rain water that your using you may know the ph but do you know the ppm,wondering if there is anything in there causing a lock out or excess
• Placing the fan next to your plants is unadvisable at this time with the rh where it at I would be concerned about windburn.
• Bringing up the humidity to 60-70 percent maybe even a bit higher for this situation might make diff you can achieve this with a wet towel in the space,it seemed you were watering alot at every other day I do realize you have done a transplant since so watch your new rh % before applying any of this advice should you choose too.
• I find that the worm castings are quite gentle on the plants and I highly recomend them,definetly a good thing.
• Wondering if any of your other ingredients have something in them that could cause a lock out or burn is the soil your using have any pre fert
• that manure is there any pellet form of the manure in the medium at this time
• where are we with a flush which will help bring up the humidity and hopefully take care of excessive build up causing lock or burn?
• Waiting for roots to appear is to late for transplantation.
• Fish emulsion (easily found) is an excelent source of N and is gentle too.

Hope this may lead to a sucsessful diag / treatment.

Scuse name spelling I will be correcting shortly.

whats ppm? is that the amount of stuff in the water?
will move the fan to mostly face the wall.
will put a damp towel in, had been using saucers but not effective.
rh at bottom since transplant has gone up to 50%
no pre fert, also basically no proper amounts of fert added by liquid.
chicken poo in pellet form but i was warned so added only 5 small pellets a pot.

they were watered thoroughly when transplanted, and every time the soil is completly dry.
what do u mean waiting for roots is too late? i see roots out the bottom of the pot after a week or so of transplanting?

thanx- bud!

PPm is the parts per million of diffrent minerals etc,what do you collect the rain water in too. I can't reaaly see a problem coming from the rain water itself as long as it's not to acidic or alkalyne.

What type of testing device do you have is it possible the calibration is out?

Thats really fast just a week to already see roots comming out how high up are your drain holes? Roots and light do not mix.
How much bigger is the container your transplanting into?
Humidity still only 50% that surprises me what did the wet towel bring it up too?

How did the roots look when you transplanted?


Still lookin for answers,
IWIC

its collected in a water butt from the houses guttering. some of it had been sitting there a while but its clear.

i only use chemical testing. dont have a digital ph tester. having problems locating one in the city. plus dont they cost £££!

the rh was actually less last time i looked at 35%. but they were drying out. now the towels wetter and plants watered so should be better.

the roots were starting to go round the sides but they werent the worst ive seen by far. the roots take no time at all to get to the bottoms whenever i transplant i thought it was normal even with massive pots. root growth is stimulated by the dryness. i usually leave them to dry out completely then water straight away. is this wrong?
