Day 50 help

[rumplestiltskin]

Hey, so it’s day 50, 1 auto, 1 fem. switched to 12/12. I thought I had both autos at first.

since the flip last week or so my plants seem to be getting unhealthier and some brown rust and some dead leaves. I give them 3 litres of water every other day with
Biobizz grow 4ml. Ph 6.3-6.5.

I only scrogged 2 weeks ago, snapped a couple of stems here and there not much though.

Older leaves at bottom are falling off and yellow, nitrogen deficiency?

4ml of biogrow is a lot at any stage, I also see some of your leaves have a claw so I'd be surprised if it's a nitrogen deficiency from under feeding.
Doesn't the Biobizz chart ask for 3ml grow and 2ml bloom for early flower?

I can't advise for sure but everytime I've used Biobizz I've run into a magnesium deficiency in early flower, my latest run a have them a teaspoon of epsom salts at switch time which stopped it happening this time.

chart says 1ml per litre and I was doing 4ml in 6 litre so thought it was less than recommended?

i do have some cal mag also I could put in?

Ah I see yes you are on the low side, I took it as you were feeding 4ml/litre.
Are you growing in soil or Coco as every other day watering for soil seems too frequent unless they are ready for an uppot.
I'd try the full 1ml/litre and see how she goes.
Personally I'd add a couple of ml of calmag as a preventative measure.

Soil, seems quite dry after a day or two so that’s what I do it more often. I’ll add some
Each time to do that as well then! hurts seeing my babies do so well then start dieing off

 

[Billpopy79]

You could just be watering too often, try leaving them for 3 days to give the bottom of the pots chance to dry and get some oxygen down to those feeder roots. Then water with a larger volume of water, if you water slowly your 5 gal pots should take over 4 litres.

See how they respond to that.

Just looking at the two plants one of the plants is a bit bigger and that’s the one where there is yellow if I look at the bottom all The older have gone yellow and some dropped off but then I look at the other plant and it’s mostly normal I’m assuming it’s a nitrogen deficiency in the bigger plant.Now it’s just determine which one is the regular feminised and which is the Auto lol

 

[rumplestiltskin]

I’m assuming that the bigger one is the regular feminised due to probably more nitrogen requirements what do you think?

 

[Billpopy79]

I would up the grow on both, they will get pretty hungry for the first couple of weeks after the flip, you could start to introduce some bloom too now.
In a couple of weeks they won't need so much N and you will want to increase the bloom.

Check out @Emilya . Her watering schedule has really made a difference for my grow.

Older leaves naturally get out grown and pruned by the plant, i would cut them leaves off. they did their job of growing more leaves and stems so yeah
