Tried Everything & Still drooping. Please Help.

[konquest]

I've got a bunch of plants grown from bagseed, most of which are around 1 month old. Most of the leaves are badly drooping and curling downwards, I'm growing in perlite, under a 600W HPS 20/4 and using Canna, Vega @ half strength due to some fert burn a few weeks ago. They are sitting just over a foot away from the light and have an oscilating fan for air circulation. Ph has been kept round low 6's, being watered 1-2 times a day by hand... I've tried cutting watering right back, i've flushed the plants with fresh water, increased watering, decreased nutrients, larger pot sizes (over time on seperate occasions) and have had minimal results, Help ???

I will have some pics up shortly and would appreciate any suggestions.
Thanks

Sounds like you need to go to a bubbler. Hand watering ? You sound like you got a clue. What's youe temps ?

[HK Slyone]

yeah what are your temps also different strains react differnt to heat when curling happens its a sign of not enough water and high heat depending on your curling so a pic would be good!

If you are running a 600w a little over a foot away...you need more than a oscillating fan...you need a small fan dedicated to the area between the light and the canopy. to blow away radiant heat!

It sounds like heatstress to me...curling leaves are usually attributed to a ph imbalance. ph for hydro MMJ, veggies differ. for MMJ ph at 5.4-5.9...experts call 5.8 optimum, but in flower the PHd's from Advanced Nutrients have found the more acidic/lower ph settings better.

hope this helps. Remember, every time you try something different, you stress the plants...stress = more males /hermies.

goodluck bro. lw

perlite in what?

What kind of system...watering times you tried?

all very important ...help us, help you, by giving us a bigger picture.

Ya, a combination of all this stuff is my guess. Definite heat issues, get the light 20 inches away or more if it doesn't have a cooled hood. go to a bubbler system (DWC, read about it, very simple), and ditch the perlite.

[latewood]

nothing wrong with perlite...

I do like hydroton the best,,and it is so reusable after cleaning and soaking in florakleen.

you'll like dwc, just take it slow, buy the right stuff, not homemade remedies, because the one real important thing in DWC is keeping the ph balanced. You don't want to constantly have to open'er up and adjust ph...believe me. that is a pain in the ass. Get some pro or GH ph up/down, and you will be glad you did

Thanks peoplez, feedback much appreciated. Im looking into the bubbler system, here's a few pics with the evident problem... So far the temp's been at around 70-75. There's also some red/ purpling on some of the stems of the drooping leaves. Watering has been at bout 12 hr intervals, I find this is a an hr or 2 off perlite running dry... If anyone could reccomend a more sufficient schedul please do... Alfoil over the perlite is new as im well over algae everywhere, however am a little sceptical as to damage it could do when heated ???

[latewood]

I thought you said you had perlite...I see hydroton, don't I?
or, are you using 2 different mediums?

OK. 1st, I can't see piks real good. they are kind of dark, and if not they are a little small for an old blind f!@#%r, like me.

q. How big are those pots?

q. are you keeping all those plants in that tub? pik4

q. could you make me a little bigger pik4

q. did you take netpots out of a system, or are you watering them in that tub? and, If so, Are the plants just sitting in fluid all the time?

sorry for all the Q's, but I can't see everything as well as i'd like to.

yeah sorry the pics turned out a bit funny, u can see them better once u click on them. the ones in pic 4 in the big tub are all in 1/2 pint cups with good drainage. None of the plants sit in fluid for any lengs of time. The hydroton u see i forgot to add has been added to the top and bottom of the pots. 85% of the medium is perlite... ill try get some clearer pics soon. Thanx....

[latewood]

If you have a long bubble stone place it in bottom of that tub, put in plants, fill the extra space with hydroton, add some water and bubble them, just like that. understand?
