leafy problems

4everhydro

whats up hydro peeps. i got a prob with curling leaves on my seedling. the curling is happening on the side of leaves not at the tip at all.so whats up help out if u can thanx.

OldintheWay

4everhydro,

Couple things to check for:
now i mention this stuff without much info. ie; age, strain, ph in res, nutes, nute strength, h202 usage, light wattage (assuming hid), light-leaf spacing, temp and humidity in room, sulfer burner?, co2 usage..............understand.

overwatering-???? it happens esp.w/seedlings
Mg deficiencies-most common def. associated with edge curl-nutes should be at 5.8ph in hydro or lockouts can occur-i can't find the chart to illustrate that but trust me.??
Crappy one part nutes with no Mg??
High Na (salt) in your res or buckets or whatever--High Na will lockout Mg--Change res more frequently to prevent salt buildup-BTW what is the ppm or ec of your tap water?
Pathogens?? Are you using h2o2 with a good synthetic 2 part nute with results grounded in botanical science...or....organic crap, magic sauces, and dream catchers....if the latter you may need to cut off the pony tail and go get some dutchmaster gold 2 parts or high quality substitute.

Don't know...give me more info and i will tell you what i think--its not likely to be major though.
Humidity, whats your humidity??

Thanks for the warm welcome guys.

i googled a prob recently and you guys came up so after trolling around a bit i figured i would give back.

but hey don't listen to me i am a noobie and don't know what the hell i am talking about in regards to canniculture --i just happened to come from a long career in commercial horticulture and floriculture--so much translates--thank jah, er..god, err...shiva for that.

changed water & nutrients good ph flushed all plants and ajusted watering intervals to 3 times daily for 30 min at a time.not using c02,growcloset set to 78 degrees,30 percent humidity,ppm of tap low but iam using purified water so even lower ppm,i usaully use supernatural aqua but decided on good old gen hydroponics 3 part,with a keep it simple feeding program,top feed bucket system 10 buckets only using 7 though.and strain white widow. so guess ill see if that corrects the problem anymore advice let me know i sure do apreciate it thanx again intheoldway. personally i think i was over watering to.great advice man!

OldintheWay

again you haven't mentioned the age--I have seen this curl in a couple f1's i grow WW being one of them--I use top drip for my mums and if yours are real young 3x 30 minutes should do it for water. up that RH to 50-55% if possible. If needed you may supplement with a LIGHT dose of a calmag product via foliar feedings or hand feedings a couple x/day.

I would recommend the use of h2o2-35%grade packaged as super oxy h2o2 its a fine product to keep the buckets crystal clear (1.7ml h2o2 per L nute soln every 3-4 days). It should be readily available at your local hydro shop or from med supply/lab equipment suppliers--packaged as 35%h2o2 and usually cheaper--also reduces trips to the hydro shops (don't know about you but I avoid those places like the plague)
H2O2 and Dutchmaster Gold 2 part is all I use in my veg room for an 8x4 tray with 70 mums-I have the occasional problem still with this same curl--BigBud and White Widow--The other thing is WW can be a bit nute sensitive so if it the only strain you are growing you can backoff the nutes with no negative effect see if that doesn't help--If you don't see deficiencies then you are fine. Don't worry about the lighter doses it is better than nute burn in WW--which it will certainly resent.
BTW if your tap water is under 200ppm you don't need to waste time or money frigging with store bought or filtered water. Mine is 140ppm and has never been a prob.
I have also assumed when you say Ph is good that you are calibrating your meter a couple times/wk.....if not please do.
Good Luck and again this curl is probably not to serious or crop threatening.

they are about twenty days old.as far as nutrient i did back off alil im at about 400 ppm also i calibrate bi weekly so about every 2 weeks.

OldintheWay

Aaahh...if your purified water is 0ppm I would push 'em a bit more 630-700 ppm--don't know but your nutes probably have 1-2%Mg with all 3 parts and could stand a higher level. Are you using a truncheon ppm meter(400ppm reads as EC .8 x 500 on one side) EC x 700 on the other side is what you want to read (8=560ppm which would be fine) a 9 or 10 (630-700) is what I would run at that point (3sets of leaves?? pushing 4th??)--you may have a true 400 just wanted to make sure.

One more thing-just checking.....you do mix each of the 3 parts seperately for your nute solution right? Mixing the concentrates together prior to adding h2o will cause all sorts of lockout and strange behavior--for the same reasons the manufacturer bottles in 3 parts.

Not second guessing you--just trying to understand all variables--should be a help to both of us. Hope things continue to grow well for you, don't hesitate to ask if you need anything.
