leafy problems

sound to me like your ppm way to high for two week old plants.I would back it off to 150 to 200ppm.You should be good to go. RC

Hey all,Good infor oldintheway,But one thing the h2o2 it kills more good mirco that the plant needs then it helps.I dont use it cause of that.I havent had many problems with root rot or other pathogens.I had a plant curl it's leaves and I didnt do anything differnce,Turned out tobe three things happening at the same time.The PH going up and down will cause a lock out of nutr,curling leaves is also over watering and humidity being too low.I flushed for 3-days with plain water.Two days before change I ph and tds the mixs and run a air stone bubbleing in it for that time,I set the ph at 5.6 and the ppm at 500 to 600.Using filter water I sometimes have to add cal-mag to the mix mostly in veg.Being to close to the light can hurt them too.{Hid}Give more infor on what you did and what's what on ph tds temp ect,, and we can pin down what's going wrong. Oldintheway is right on the money too keep it simple. Peace

Organic ops rely on beneficial bacteria to keep things in check and break down organic compounds into there most basic form usable by the plant, h2o2 will prevent this by eradicating all microbes and bacterias (benefical or otherwise)--with synthetic nutes the macro, micro and trace elements are in there simplest form ready for uptake by the only organism that I have in my op-cannabis.
I prefer this since it is hard to know without a lab and a good microscope if beneficials are winning the battle between good and evil.
Synthetics plus h2o2=success

BTW Calmag is a great product for Mg supplement and I use it as well--only as needed during veg.
Mg lockout occurs below 5.7 according to most charts and running a 5.8 that drifts up to 5.9 or 6 should be fine--I don't adjust down till mine hits 6--then i drop to 5.7. This usually holds for 4-6days
Toke is on the money regarding low humidity, it will cause this curl as well--make sure you have an accurate hygrometer then make sure RH is 50-60%

happy to report all leaves are strait and back to healthy look,with the exception of one plant but its leaves look like their going back to normal.ill see in a day or 2.

So.........overwatering was the cause......or did you add some supps......or both? funny this guy looks like a younger me....think father time meets this guy

yeah over watering and probably a build up of salt in the rockwool block no supps added just adjusted feedind times,ph,res change.still waiting on a mist maker from ebay to get that humidity up though.
