If the grow room cools down during those 6 hours of darkness that can make stems go purple/ red- i get that all winter.
I would try a few feedings with a half spoon per litre

 

[Cringer]

Ok bro I try it
But Phosphorus deficiency are also possible. I drop the Bloom nutes up too

 

[Cringer]

I water with run off right know the PH from the Run off are 6.7. So no worry about the pH right?

Danke

How I can fix the PH Problem? Next watering with more Run off ore Flushing with PH 6.5 water?

 

[blowyourmind]

Flush 2 times with decocted water.
After a week use only Rain water.
Rain water is 6.0..
After 3 weeks u can feed her again..With Rain water

Use always Rain water!!
Check always your ph/ec if u use boosters..

Cheers

@Andi ive only been growing for 18 months not 18 years but i disagree with that info.
6.7 isnt so bad. 6.3-6.5 is about perfect.
Going below 6.0 you risk locking out phosphorus, calcium and magnesium.
5.8-6.2 is what i aim for in coco and hydro.

Biobizz lightmix is very light and only really feeds an auto for 2 weeks.
So at day 41 the only nutrients are the ones you provide. After 3 weeks of just plain water i think the plant would be starved and yellow top to bottom

I would give half a dose P/K, full dose calmag, 10 g epsom salt and GH Urtica.
I use all minerals except P every week. P every 2 weeks. Too much P is toxic.

I don't have cal-mag only biobizz nutrients fish, grow, algamic, and bloom. It's funny how quick the deficiency she showing know my plant looking perfect 38 days I give her nutrients at the beginning and after strech is over i lower the Grow nutes to 1.5 and give 3ml bloom. But I never water with run off I gave her maximal 1 Liter water every 1-2 days. The question is what I doing wrong? Maybe watering every time with run off but TaNg didn't also with no Run off. Ore the 1.5 ml grow feeding was not enough biobizz feeding plan says: 4ml grow and 4ml bloom in flower modus in light mix. I road hazys thread he only give maximal 1.5ml and 4ml bloom but he grow with hps not led.
