Help, my babies! Gigantic Pictures

What's going on with these leaves? They're getting skinny and trying to lean.

My 400W MH is 23 inches away from the tallest one (close left) and 26 inches from the 2nd tallest one (far right). Nutes around 370PPM and those plant's ages are really different x.x. Except the smallest two are only a day or 2 apart. Room temps around 72-82F. pH levels should be around 5.4-5.7 (digital pH meter in the mail )...

I think it might be a humidity problem (too dry), maybe the light heat? hmm 23 inches... or perhaps the pH level is too acidic. Please help !

i was wondering what strain it is?? i have a few that look exactly like yours. i thought they may be lowryders. they grew more like climbing rose bushes and kept leaning in an arc shape rather than growing straight up. i've regenerated them and trimming them way back has finally made them grow up instead of over. do you know what strain you have?? thanks

right on med. But if its only a 400 watt light you can put it closer. one foot above is sufficient. If you don't move it down they will grow up to the light and be leggy and sparse.

They won't grow leggy if the light is over a foot away. Only one stem seems to be leaning. Check you ph levels.

The strain is Northern Lights x Big Bud and I've had a few minor problems with this first grow (ph was too low, light too high, etc!! can't believe they're even alive xD).

So I should try n drop the light? It has no glass or hood vent . Yeah I can't wait for that digital ph meter...ah god, where is it....;D

Dude ur plants look fine and u can even lower ur light (gradualy and watch how the plants response)...appart from that..happy grow

i agree they look pretty good/ relax a lil and enjoy the gardening experiance.
