Plant problem please help

Plant problem please help


Plants are now 3 weeks old they been doing great up until last week when leaves started curling down an shriveling up.


Its in a flood an drain system I am using canna nutes, ppm is on 700 PH 5.8 room temps are 79f daytime 68f night time lights off.


First two pics are of the same plant the roots are still growing an are nice an white.


3rd an 4th pics are of an other plant that is in the same system getting the same feeds an temps an looks really good.


Any help would be really appreciated.


Thanks

Wouldn't you rather get no replies from people who are not sure what your problem is, instead of a bunch of shit from people that are not sure??
Here is a chart for soil that I came across one day, hopefully you can derive something from it.
When I look at your plants, my first guess would be overwater with overheating, but from what you say, that sounds OK.
Your second plant that you say 'looks really good', I wouldn't venture that far.
It just looks like it is a few days behind number 1 plant.
Do you want to tell us what 'Canna nutes" you are using?

GT is right...early flower is 800 to 1000 then increase it every week peaking at the highest your plant can take without burning. When you grow a new strain you're not familiar with it's best to get to around 1400 then increase it slowly by 50 ppm each time till you see the slightest little burn evidence on the leaves then back it off by 50 and you'll be maximizing the food strength they can take.


Mj that doesn't like high food doses can usually take up to 1200 to 1400 ppm max and some nute pigs in soil can take up to 2000ppm. All strains have their likes/dislikes.


At the end of flowering you should reduce the strenghth of feed every time till you get right down to your clearing/flushing stage.


Do things gradually. For example if it's a 9 week strain in flower you could go:
week 1: 1000
" " 2: 1200
" " 3: 1400
" " 4: 1600
" " 5: 1600
" " 6: 1400
" " 7: 1000
" " 8: 300
" " 9: 0


Your veg stage should also increase in strength up to the flowering stage.


Soil growing isn't hard to fix a burning problem if you are only increasing your strength slowly; especially if you have drain holes for flushing.
