Help needed with autoflowers - first time grower

[hijodef]

Hello all

I am a first time grower from Northern Europe.

I would really appreciate your feedback on my plants. I have two autoflowers in my grow tent:

A on the left is CBD Auto Blackberry Kush (Dutch Passion)
B on the right is Purple Kush CBD 1:1 (Auto)

A is 8 weeks old, B is 6 weeks old.

10 gallon pots half filled with BioBizz Light-Mix soil.
2 Viparspectra P1000 (100W) growlights, one for each.
Temperature 24 C / 75 F, RH around 50%.

Watering
A: 2,5 litres / 0,54 gallons every second day
B: 2,0 litres / 0,44 gallons every second day

Feeding
BioBizz Bio Grow A: 6ml per each watering B: 3ml per each watering
BioBizz Bio Bloom A: 6ml per each watering B: 3ml per each watering
BioBizz CalMag A: 1ml per each watering B: 1ml per each watering

Tap water pH is almost 8. I lower it with lemon juice to 5.5-6 and let it rest one night before watering, and check pH before watering.

PROBLEMS
A: Yellowing leaves and tips of leaves turning brown. Leaves curl down.
B: Tips of leaves turning yellow. Leaves curl down.

What is causing the symptoms? What do you think? What should I do?
Thanks for the help!

Welcome to 420

Don't think you need so much grow in flower
Maybe water a little less often now they are in flower too

Welcome to 420Magazine my friend.
Beautiful garden.
My only concern would be your watering.
Every 2 days is your schedule not hers.
Wait a bit longer for air to permeate the soil.
Roots need air too.
And water until you get run-off, not a set amount.
What ever amount it takes to get it out the bottom.
Then let it dry a bit.
Girls are doing well though.
Do you have your lights at 100%?


Stay safe

Thanks!
I have my lights at 100%.
Will adjust the watering as recommended

Since they won't stretch anymore I'd bring them closer a couple inches see how they do.
Light schedule for autos is popular at 20 on 4 off what do you like?

Hello all

I am a first time grower from Northern Europe.

I would really appreciate your feedback on my plants. I have two autoflowers in my grow tent:

A on the left is CBD Auto Blackberry Kush (Dutch Passion)
B on the right is Purple Kush CBD 1:1 (Auto)

A is 8 weeks old, B is 6 weeks old.

your plants look fantastic for a first grow.

10 gallon pots half filled with BioBizz Light-Mix soil.
2 Viparspectra P1000 (100W) growlights, one for each.
Temperature 24 C / 75 F, RH around 50%.

temps are a little low by about 2 - 4c. cannabis likes it just a touch higher. they'll still do fine at your temps but may take a little longer to mature.

Watering
A: 2,5 litres / 0,54 gallons every second day
B: 2,0 litres / 0,44 gallons every second day

have a read through this on proper watering / feeding

The Proper Way To Water A Potted Plant

The Proper Way to Water a Potted Plant Also covered: the importance of pH and why we successively up-pot How to Water Over the last several years I have put a lot of study into this, and I feel that I can now define the proper way to water a potted plant. Keep in mind that this discussion...

Feeding
BioBizz Bio Grow A: 6ml per each watering B: 3ml per each watering
BioBizz Bio Bloom A: 6ml per each watering B: 3ml per each watering
BioBizz CalMag A: 1ml per each watering B: 1ml per each watering

Tap water pH is almost 8. I lower it with lemon juice to 5.5-6 and let it rest one night before watering, and check pH before watering.

lemon juice isn't all that stable. i'd use a proper ph down product.

PROBLEMS
A: Yellowing leaves and tips of leaves turning brown. Leaves curl down.

looks like it wants a touch more calmag.

B: Tips of leaves turning yellow. Leaves curl down.

it looks like it may have been fed a bit high in n. downward claw is often a sign. most of the tipping looks to be mild nute burn which is not a bad sign.

What is causing the symptoms? What do you think? What should I do?

keep watch on them and look for signs of hunger. they feed a bith higher on the pk in flower

Update!

I let "B" dry one more day, to my senses it felt super dry.
I added a total of 3ml grow and 3ml bloom, 0.5ml calmag.
I ended up giving it a total of 4.5 liters (1 gallon) water. pH 5.5

I got 0.7 liters (0.15 gallons) / 15% runoff with following specs:
pH 6,9
1350 ppm
EC 2,7 mS/cm

I actually don't understand much of ppm or EC. It seems that they are a bit above ideal?

Is pH way too high?

What do you make of this?

Thanks again!

If I set my ph in soil I set it to 6.3 for maximum nutritional uptake.
Are you following the schedule that comes with your nutrients.
Ppm's in soil generally aren't measured.
Just follow the schedule per week of Flower.
I don't measure run off even in coco.
It can cause you to chase your tail.
As long as they are healthy it shouldn't matter.
