Need help!!!

Gsc auto from fastbuds. 32 days old. 250hps. bio bizz light mix and biobizz.nutes.

These things went wild up until yesterday. the veg was outstanding and they are wide and bushy. flowering has begun.

Bottom leaves are yellowing and dyinng. even leaves up the stems are yellowing and dying. ive been giving them 2ml bio gow per 2litre of water. is this not enough? im also seeing a bit of drooping on top leaves. will try and get a pic tomorrow but does anyone know whats happening?

too much

slow it down

avoid over watering

a pic is good

good luck

1ml/L doesn't sound like enough to me. I've never used Bio-Biz but spent a lot of time teaching a kid in Scotland how to get his grow going and that's what he used. Sounds like they're hungry.

Could be overwatering to like vostok mentioned so if you're not letting them get pretty dry between waterings you should. Heft the pots because the bottom half can be soaking and going rotten while the top half is dry.

So the roots are fine and i let the pots dry out before re watering. the bottoms are dry as well as the top and pots are light. i tried a bigger feed last night to see but pics below.

You can see the canopy is pretty wide (lst) and not much light pen below. some bottom leaves dying some in the middle. this is one plant but they are all the same!!

Also, would putting 2 2700 cfls in help or not worth it?

Now this has happened too.....

I'm not seeing anything wrong other than some old leaves giving it up. They will get susceptible to fungus and mold and that's what the necrotic brown spots look like. Just pinch them off and get rid of them in the compost.

Your plants are looking nice overall and the rest of the leaves seem real healthy.

Never fret about old leaves at the bottom dying as it's pretty normal. It's when it's happening to lots and moving up the plant that it's likely a deficiency or bad pH.

You got the bloom nutes too? They should be getting some of that. I think they are hungry and they need lots more to eat when flowering starts and they go into stretch. Check out the website for their feeding schedule but be careful as most say to feed too much.

Okay thanks guys. ive upped the bloom nutes to the recomended 3ml per l.

theres plenty of green leaves but im worrying as the yellows are starting to climb up as you can kind of see in the pic.

I feel like im being ovee cautious perhaps. just dont want to ruin it after such a strong start!

I'm pretty sure she's just hungry. Some strains will start showing yellow leaves fairly early in flowering but yours looks like a bit too much for even a strain like that.

Doubtful that very yellow leaves will recover but she'll likely put out more with the feeding and should do OK.

The yellow seems to be going up the plant. some high up leaves are showing yellowing. could this be a ph problem? maybe ill use bottled water now......
