Leaves are drooping

[Whitekong]

Well my plants are about 1 1/2 weeks old ive transplanted them into rockwool blocks. Near the end of the week they are starting too droop but the younger plants are doing great. was wondering what might cause this.

[fasts102376]

have any pics?

[tinytoon]

need more info.
you transplanted into RW blocks from what?
did you soak blocks first?
how often you water?
PH?
light, how much and what size?

and anything else you can throw in, the more you give the peeps that are reading this the more they can try and give back :thumbsup:

[Whitekong]

they are watered every hour and a half. they were soaked before transplanted, and the PH is between 5.5-6.5. we have the temp at around 80 degrees. the older plants were transported from California as well as the younger, which might have caused it? they have light 18 hours a day, 1000watts.

Sounds to me like to much water, leaves want to get bigger but are loaded with to much. It cant hang yet..

Try cutting your watering times in half. every 3 hrs if problem persist take watering every 4 hours as needed.

If you experience any additional problems or have difficulty breathing please consult your thread.

[Whitekong]

thanks ill lengthen time in between watering.

[Whitekong]

wanted to also add, we're growing 3 types. Old Grandaddy Purple which is coming back to life, LA Social which is doing perfect, and Jackey whites which are the ones which seem to be drooping, but i didnt extend the time between waterings about 2 1/2 hours.

[tinytoon]

well I'm guessing your either running an E&F setup or drip, cant tell which since you never said. If it is E&F I flood mine about every 4 hours but only during "light" hours, flood lasts 15 mins from start to stop

[Whitekong]

by E&F do you mean you have a tub for your plants that you flood, if so thats what we're running. we flood every 2 1/2 hours until lights off. But we're using rock wool which I've heard you cant over water. I will try to get pics from my phone to show.

[tinytoon]

oh you can over water RW just about like everything else. RW holds water very well, in fact now that I dont use it anymore (clone in Rapid Rooter and right into Hydrotron) I have had zero algae when plants were small and creating no shade at base. RW also has a bad habit of holding salts very well too so Plain Ph'd water flushes every couple weeks wont hurt or you can spend more cash and buy some Clearex and do same thing.

and yes the tub thing that floods is E&F ( Ebb and Flow for those taking notes ......... there will be a test!!)

[Whitekong]

hmmmm that is a great idea, so rock wool can develop algae and stuff like that easily?

[tinytoon]

yes if exposed to direct light. they make covers to go on the tops of the blocks but I just made mine own out of the black/white poly plastic when I was using RW. Once the canopy fills you dont have to worry so much as algae wont grow in the shade.

[Whitekong]

here are some pictures of something that might be mold and the leaves drooping.

[Whitekong]

just tell me if you need any more pics and of what. i removed that black stuff from the rock wool, tomorrow i am going to the store and getting the stuff to cover the tops of the blocks.

[tinytoon]

yup that black crap was mold/algae building up. When watering dont water the entire block, only about 2/3 to 3/4 of it (from bottom to top of course).

[Whitekong]

well i guess first crops arent perfect, i started filling the bin with hydroton. thinking about moving the blocks into buckets filled with hydroton.

[tinytoon]

check this out and all can be purchased at Walmart except the fill and drain tubes that came from a hydro shop but I'm sure something can be found in the plumbing dept of home dePOT!! :thumbsup:
2 Sterlite tubs, couple 6" air stones and a dual outlet air pump from pet dept, and the pump you can get from either walmart, home dePOT or Lowes in the garden section. setup runs on 6 gals of water and can do 2 good sized, 3 med sized or 4 small plants your choice.

[Whitekong]

we have the same setup, we got all our stuff at a hydroponics store. but i am wondering if i should take the plastic off the sides of the rock wool. Also we put hydro ton in today, but its not as high as I'd like so this week sometime we're going to buy another bag. the plants that are drooping came from seeds bought from , but the plants that are doing great were from a friend.

and e&f is what?? :jointsmile:
ebb and ....

flow :thumbsup:

the side plastic on the blocks I guess could influence the roots to go down but my main reason for taking off was air flow. with plastic on there is less air flow and blocks will hold water even longer as there is less surface area for evaporation, but that is just my theory :jointsmile:
