Hey there guys,

I'm just coming up to week 6 on my second ever grow. I'm growing autoflowers. 2x think different and 1x red poison. I'm growing under a 400w HPS. I'm growing in biobizz all mix. I'm using bio-grow and bio-bloom from biobizz. I started feeding at about 3 weeks. 1ml grow per ltr and went up to 2ml per ltr over a week. My plants got real dark and one was clawing... So I cut back on grow. I'm now on bloom only. Currently about 2ml per ltr, they get fed once every 5 days ish and water between. Ph of about 6.5. Temperature when lights on are about 27c lights off 15c. Humidity lights on about 37%. Lights off 55%-60%.

I have noticed what looks like rusr spots dotted around the leaves, no sign of any bugs.
I have also noticed most leaf stems are red.
also on one plant there are a couple of pale leaves near the top and they have red vains... Only a couple of leaves on one plant.

I cant work out exactly what's going on or how worried I should be... If at all lol.

would love some opinions and a bit of advice... Uf any of you think you can help. Id be very appreciative.

thanks in advance.

Il post a load of pics below to help see what's occurring.

peace

p.s. All plants have ben low stress trained, incase you wonders what shape they were lol

I grow in soil and use the same nutes as you and grow under hps and have done for years ( used the biobizz all mix loads of times)

you could give the plants 2ml of grow and 3ml of boom every water and the plant would be ok

best results for me was using 1ml of grow and 2 ml of bloom
did you add epson salts in early flower asmy plants alway needed it ?

ok cool cheers mate, I found that I needed to stop the grow on the red poison because of how green it got, also the leaves were clawing as if it was N toxic. That's why I'm on just bloom now. Have u ever had the rust spots for any reason? You can see the spits if you zoom in on the pic of all 3 plants together. Iv just given them some Epsom salts today, this was the first dose this grow.

cheers

yer you could be right about the N toxic as some plants need more nutes than others
often get rust spots, think is down to me dripping nutes on the leaves when watering them lol
