1 Plant
Flowering stage now 29 days (66 days totally)
Indoor
Soil
The mix is 50% of soil + 25% vermiculite + 25% perlite. drainage is kermesite
The size of pot is 10L
LED light 150W (main) + 2*18W Fluro by Osram + 54W LED
Air cooled
The temperature is 29/23
RH is 6.5 into the pot. Out (bottom) measured is 7.2
Using the GHE Micro and Bloom
Watering is every two days (the schedule is feeding - water - water - feeding (each step every two days))
Mineral fertilizers used (GHE Micro 5-0-1; Bloom 0-5-4). doze is 2.1 Micro + 2.3 Bloom
The room is 1.2*0.6*2.5 meters

The problem is that some leaves have some kind of defects and becoming yellow.Suspects are over watering, pH or nutrients.

You have bugs imo. Nutrition problems usually affect the middle leaves at first, did you notice where it started?

Stop applying water to your actual plant only water soil. I would stop feed for a week let plants,soil dry out. Water as necessary and re feed when they look healthier

Thanx, bro. I also suspect the over watering. The growth has stopped and one of the suspects is root rot. I did a flush with cleaner 2 times. last time on the 14th. I will do the new photos today as the ones I gave were from the 10th. but the situation is not getting better :(

No worries dude, you might want to try and ventilate the area a bit better it helps with recovery. Root rot sucks water is the enemy for a while so add as little as possible and hop for the best. Happy smoking
 
Here are the new photos.

Thanx, Bro!
 
NUTE BURN. Flush, continue with 1/2 the amount you were feeding and work your way back up from there if you have to.
 
Yes...you have a feeding schedule...this is how you water when incorporating into a feeding schedule...If you know you are going to feed tmrw (for example) and the pot is 75% dry...just give it enough water to make it till you feed her the next day. Runoff is bs imho. I water my 5 gal pots with 1 gal of water, an hour later I come back a have some dribbles on the floor. Thats about how much runoff you need, not water pissing all over your floor. The dryer the plant stays on top (IM glad you stopped spraying), will make for more tricomes on your buds. sticky sticky. when you water you are creating enough humidity in the room. My RH in my flwr is below 20%, when I water it will bump to 40 maybe even 50%

the idea of runoff was to make sure that the pH on out is below 7 to have a best nutrients' consumption. but will try to give less water. this is my second grow and I was successful during the first one. with out any pH measurements and so on. Just started to pay science this time :(
 
I checked the ph on my water once...it was perfect so I never bothered to check it again. I give the nutes into my soil and dont bother checking runoff. Never had any probs. Probably the same thing you did on your first grow. I have maybe picked off 2-3 yellow leaves off each plant during their entire lifespan.
 
Foliar feeding is an 'advanced' technique IMVHO, isn't needed, and shouldn't be used during flower. I've recently discovered the benefits of spraying a kelp extract while in veg(something like Floralicious+)

Did a flush on the 14th and no reaction since then. also did it on the 1st, same s..t.

Flushing won't bring about any noticable changes-the leaves that are damaged are damaged, and may even continue to get worse as they die. Look at your new growth- if that is coming in nice and green then you probably corrected the problem. Once you damage leaves due to nute burn they don't recover.

In soil, corrections can take a while to manifest.
