Volker, check on those red petioles of yours. The plants look okay but there are a few trouble spots... can't see too well because of the odd lighting, but in the bottom right of the pic there's some fan leaves that may be showing def/burn/lockout... better lit pics on those?
stinkyattic Reviewed by stinkyattic on . Twisted blades? OK the plant in question is a 3 day old Northern. I grow in sunshine mix 4(soil w/ perlite) and use chemicle nutes, the pH is at about 6.5. I use a 400w MH bulb. The temp is a steady 79-80, and humidity is 28-35%. Today I flushed, transplanted then fed with 1/2 concentrated 10-10-10. Then a few hours later once they had a chance to absorbe the water I LST'ed a little to expose some branchs. Now it is only one blade on one leaf that is twisting. I don't know what it could be from...blushing...it Rating: 5
