I grew with T5 clfs an had perfect short internodes structure, but recently I have swiched to the LED lightening and now I have plants growing with long internodes, more of that on one node i have only one branch (vegetative axillary bud) and a leaf, hoever I want to have two branches and two leafes on each node. What could be the couse of the problem. Lower temps, light spectra, light cycle (at 18/6 now mothers and clones grow in the same cabinet)?
Thankyou
T5s are great. If I were you I'd go back to using them as your primary lighting source and stick to LEDs as supplemental side lighting. But that's just me.
I'm not sure what the deal with the one branch is, but it just sounds like you don't have enough light in the right spectrum, like whatever the LEDs are has missed the mark.
that's a tough one ... just a stretch, but is it possible the plant was stressed, and is starting to get distorted or weird on ya ? ... :smokin:
What wavelength LED's are you using? Red (645)/Far red (>660) will result in node elongation (remove far red to fix it), as will a lack of blue (430,440,460). Blues specifically promote short internode spacing.
