UNKNOWN DEFICIENCY IN MY INDOOR.

[elneandy]

Hi Everyone.
Im having a hard time to identify and correct what I suppose its a nutrient deficiency in my 1st week of flowering. Maybe its a nutrient burn, But I only use Delta9 ( Cannabiogen ) 1 night before shifting to the flowering stage ( this is the 5th day of flowering ) .

I have already look at the forum but I cant really seem to identify the problem.

Im growing in a 4x4 Garden High Pro Tent, under a 600HPS light, in 20 liters pots ( around 5 gallon pots ).
Im measuring and using 6.5Ph before watering the plants, and Im sure i'm not over-watering them, as I lift the pots regularly to test them before watering them,

Any ideas or help I would greatly appreciate it.

Have a great day everyone.

Everyone who ever overwater are sure they didn't. What are you growing medium. And how much and how often do you water.

Try adding cal/mag. I only water when my plants need it.

Try reading ppm an ph runoff

Hi Bro, im
Watering every 3-4 days.
I lift the pots before every time and I don’t water unless I feel the pots are really light.
Does this looks like overwatering ??

thanks a lot for replying

Yes. Exactly how much water until soaked to runoff? Is it in soil? Did you add extra perlite?

Hi Bro,

For watering I do it slowly, first I moist the soil a little and half an hour later I use the rest of the water. I will measure and give you and idea on how much water I use until runoff.

I use a local substrate that is basically Peat (Sphagnum ) , Perlite , Compost, density is 140 - 180 Kg/m3, but I also added some vermiculite.

If I pour too much water the substrate runoff basically 4 seconds later, so I take like 20-30 minutes between watering them.

As stated before I also measure ad adjust Ph to 6.5.

Anyway I will measure the time until the soil runoff when start watering and let you know.

Thanks a lot for your advice.
