Live Stoner Chat 1st Grow need Help

[anonin]

Hello,
This is my 1 st grow and my autos are 22 days old in 5 gal pots and yesterday it showed sex and just started to turn yellow on the tips of the upper leaves. I gave their first feed last week with Biobizz grow, heaven and acti vera 0.6mg/l each and after 4 days from the feed i watered them with plain ph'ed water. And today i watered them again with plain water in case it could be a nutrient burn but as biobizz is organic and i only gave them 1/3 of the recommended dosage it just seems weird.Can someone please tell me whats wrong with my Blue Dream or is it just normal? Also I'm using 400w mh with 24hours light cycle(45 cm away from the light), when do you think i should switch to 400 hps? Thanks.

Biobizz can burn plants trust me,I'd just give them a little less grow and they'll be fine,when they stop stretching you can switch to hps!

Welcome to AFN!

Thats the typical start of nute burn. I dont use the biobizz nute line or medium, but its important to know what is in your medium. Depending on what medium you are using, your plants might not need nutes for the first 4 weeks or so.. What medium are you using?

I am using Biobizz light mix. Do you have any recommendations about feeding? I have full product line of Biobizz and this is the schedule i follow

Also i wanna switch to hps nowadays because i want some stretch as my autos are really small and bushy, i think it is because of 24/0 light cycle, do you think switching to hps would stress my plants? And do i need to put the strains in dark for a while before switching? Thanks again guys for being friendly and helpful

Hps is fine, go for it.

They will stretch natural, they look great!

Cheers mate. I am wondering if anyone knows what are these brown dots on two seperate leaves of only 1 plant and white dots which look and feel like a trace of lime on each plants as i have a cool mist humidifier which i use tap water with. Need help again.)

if you using a mister then thats my guess as its only 2 leaves.allways a good idea to inspect leaves especially undersides for tiny bugs if ya see tiny spots.
biobizz lightmix has very little nutes,should be fine to feed from week 2.
this is what happened last time i used biobizz nutes/soil

as im a crap and lazy grower i wouldnt recommend to following an eejit,a very rough guide.
good luck.
