Small holes in leaves

[jboog0]

Hello,

This is my first grow and I started an NL plant from seed. Medium is canna coco with the canno nutrient regimen (A/B, rhizotonic, cannazym so far). On the oldest two sets of leaves some small holes with yellow around them (from the top). I know the PH for my last two mixtures were high, but could it be anything else. Suggestions on quickest way to fix it aside from getting the right ph next time?

This one is 3 weeks from germination, temp's kept between 70 - 80F, rh 45 - 65%

Also I attached a picture from one of the lower branches. Signs of female or another set of leaves?

Thanks

Check around for insects just to be sure, keep the place clean.
At this age is quite sure that they are new leafs and not pre-flower, the plant still young. Here a link (http://cannabis.com/growing/sexing-what-are-preflowers.html) for more information.

there is nothing wrong with your plant.

wait at least 28 days to be looking for sex organs.

thanks for the reply. Could fruit flies cause problems? or spiders? Those would be the two main insects around my place. I keep it pretty clean, but its also not a sealed room or anything. Suggestions for cleaning supplies that wouldn't mess with the plants or suggestions for pest control?

Thanks again

nice plant! As Lucifer said...check carefully for insects/bugs and remember...their job is to hide from you so a quick glance here or there isn't enough. Go over them thoroughly with a magnifying glass if you have to.

Yes with question 2 as well......Lucifer is right again.......happy new growth starting.
