Hey guys,
I was wondering if someone could help out with a minor/major (hopefully minor lol) problem..
Ive recently purchaced a full indoor hydroponics system,
everything has looked fine up until now, they were a nice healthy 2 inches with first leaves and signs of secondary's..
problem came when the water was changed for the first time, the plants drooped from the stalk unexpectedly pretty much 90 degrees down. This was corrected with carefully placed coctail sticks holding up the drooping babys, ph was fine, only difference is full strength nutreant solution was used as aposed to half strength as roots were visable in the matting.
They started to gain strength and all of a sudden a few of the leaves browned and crisped up suddenly in the space of about 4 hours.. Using an HPS light, running 6 inches above the tops, my first inclination was heat stress, so the light was moved up higher although not much improovement was noticed at first...
However the fact that full strength nutrient has been used, 'nutrient burn' appears to fit the scene as they worsen closer to where the pump introduces water to the system..
Should the pump be on 24/7? or should it be on a timed cycle of half an hour for every 3 hours?
Ive been running the pump 24/7 on low until this problem occured, and i read up on overwatering / nutrient burn.. So over the last few days I have rigged the pump on a timer to water the plants matting tray for half an hour every 3 hours, this seems to have improved the 2 plants further away from the pump, however the 1 closest to still seems weak, yellow/browny, and short.
The other two seem to have made a 80% recovery, with minimal drooping and second, even third leaves/branches showing through.
Does this sound like nutrient burn or is there something more sinister at work?
Also how high should an HPS light be from vegetative plants, i know there more reccomended for flowering however budget played a major part in decision of equipment..
Since in the second 2 plants secondary leaves look strong and branches are starting to become visable and are looking healthy aside from a tiny bit of brown on the tips (which looks much better than before), is there any chance of salvaging these??
Thanks for reading, Ill appreciate any input as im pretty green to this hobby (no pun intended) lol
Cheers
