new grower !! CFL LST help and advice please!

i have noticed that some more of my leaves have started to yellow, i don't kno why this is happening, any one know? also it looks like a burn on the end of one of my leaves but it wasn't close to a light either i misplaced it or something this is something else maybe relating to why my leaves are turning yellow? after these pictures i plucked those yellow leaves off and repotted into some bigger pots and changed the lights form 2 15w daylight and one 20w red spec bulb to 2 20w red spec bulbs and 1 15 w daylight and i'm going to give them 24 hours of dark then switch to 12/12 and start flowering gonna take some more pics of my plant soon ,



comments please

That first pic is definitely some kind of burn, unless you have a rabbit or deer that likes to snack on your plants! It's definitely damage from an outside source, not caused by anything botanically wrong with the plant... As for the yellowing, IMO it looks like a very minor nute deficiency. Most likely need to increase the amount of N in your nute watering. I had some similar issues with yellowing and did a full flush (in the "Make it Rain" tradition) and then added some double strength veg nutes and it seemed to right itself. What's your humidity and temp like? If you look at my grow thread https://www.rollitup.org/grow-journals/417627-n00bgrowers-2nd-freezer-conversion-crop.html you'll see some similar yellowing and how it righted itself later in the grow.

yh thanks for the advice, gonna start using a little more nutes, yh i think it might be a burn don't know how it happened though, just got out of my 36 hour dark period starting 12/12 now, really nervous about determining whether there male or female hoping so much for girls, anyone know how long till i can tell, i'm seeing no signs or sex yet

Could take up to 2 weeks depending on strain and grow conditions

You could give nutes or you could repot to a bigger pot and leave of the nutes a bit longer.

Determining the sex is rather easy. You will either see 2 pistols forming on top of the nodes(2 hairs basically) or little pollen sacks that look just like a nutsack. The pollen sacks grow below the nodes. Also, it is quite common for the lower leaves to turn yellow during flowering. This means the majority of the plant's efforts are going to bud production.

getting really worried now i've been looking at my plant and i think i can see little balls on BOTH of them hoping it its still to early to tell but its my first time growing and i dont really kno what to look out for, what do you think of my progress so far and whether its male or female ?

Looking good man. might not be male just yet. Wait til you see clusters. Even if it's a pollen sac, it won't open until there's a cluster.

i kno these pictures arnt great again, but the pre flowers have grown abit more, i'm still seeing no hairs coming off them but they deffo don't look like pollen sacks to me, using some nutes now probs not the best choice but hopefully it will give them a little boost, do you think there is any chance of me having them ready by late june? because i'm going away for a week on the 2nd of july, so if not i will have to work out some watering system or get someone to do it for me
