Hi everyone,

Id be very grateful if someone could give me advice as ive run into a bit of trouble with my ladies.
I will try to simplify the presentation to make easier for the reader.
I started an indoor organic grow 9 weeks ago.

4 seeds
Strains : 1 white widow / indica
1 hifi 4g / hybrid
2 blueberry / indica

Tent :1.2m x 1.2m x 2m high
Soil : canna terra pro.
light : kingbo 2000w led

Seedling : Week 1 - 2
1l pots / temp 24 - 27•C / RH 75 - 70%

After 2 weeks of seedling stage i then potted up to 12l ( 3 gallon ) pots to start veg.

veg : Week 2 - 4
12l ( 3 gallon ) temp 24 - 27•C / RH 70 - 65%

I continued veg for a further 2 weeks but i potted up to 30l ( 7 gallon fabric pots )

veg : Week 4 - 6
30l ( 7 gallon ) temp 24 - 27•C / RH 65 - 60%

after 6 weeks of veg i didnt use any nutrients as the plants were thriving and apparently canna terra pro has enough to last the first 5 - 6 weeks.

I then decided to start flower phase, 12 / 12 lighting

Flower : Week 1 - 2
Temp 24 - 27•C / RH 60 - 55 %




Top dressed With organic dry amendments
30ml of each....

bat guano 1.10.1
Palm tree ashes 0.1.30
Ecothrive charge 3.2.3
Bone meal 3.9.0

i watered the top dressing in with tea consisting of
500ml worm castings
2 tbsp molasses
1/4 tbsp epsom salts
Ph’d using lemon juice to 6.3ph in 5 gallon bucket.

i give each plant approx 2 1/2 gallons of water each to achieve approx 20% run off.

Flower : Week 3
Temp 23 - 26•c / RH 55 - 50%

this is where i noticed yellow leaves in middle of canopy on 2 plants. 1 of the blueberry and hifi 4g.
Do you think it could be from too many nutrients or not enough ?
Ive been trying to do some research and cant seem to get anywhere. I doubt its a nitrogen deficiency as the yellow leaves are in the middle / upper section, aswell as at the bottom.
the only thing i know that i might have contributed too was watering only once a week and letting the soil dry right out. Although, when i water them, as stated above, i give them a good soak with 2 1/2 gallons each achieving approx 20% run off.
i did water them yesterday without amendments and just ph’d water with 2 tbsp molasses and 1/2 tbsp epsom salts.
if anyone can give me any advice it would be very much appreciated I can attach pics if need be but because its under purple leds its hard to see.
