[FONT="]Hy folks,[/FONT]

[FONT="]I have 5 indica dominant strains, they are 45 days old from popping out. I germinated on paper towel then i put them in root riot. I transplanted them into 0,5L (1/8 gallon) 100% Plagron coco. I don’t rinsed or precharged the coco (the runoff EC was low). I feed them around 300-400 ppm on 0,5 scale. Last Friday i transplanted them into 2,2 liter (~0,5 gallon) Plagron coco and feed them 500 ppm. PH alwasy 5,8. I always water to 10-20% runoff (the water amount is about 25% of the pot size). I use RO water with BioNova Coco Forte A+B. I use also a root tonic from House and Garden called Roots Excelurator Gold (0,3 ml/liter around 20 ppm).[/FONT]

[FONT="]My setup:[/FONT]
[FONT="]1m x 1m x 1,8m tent[/FONT]
[FONT="]250W CMH with Hydrofarm Radiant air cooled hood[/FONT]
[FONT="]24-25 Celsius daytime[/FONT]
[FONT="]21-22 Celsius nighttime[/FONT]
[FONT="]75-80% RH daytime[/FONT]
[FONT="]65-70% RH nighttime[/FONT]

[FONT="]I tried the wet-dry cycle to help roots fill out the pot, so i water every 2-3 days, when the weight of the pot is the same when i filled the pot out of the bag. When I transplant last Friday the pots was full of roots, but they were thin. I can’t decide this is overwatering (lack of oxygen) / underwatering or over/under fertilising. In my opinion this is not overfeeding because the runoff EC is the same as the inlet EC. One thing i see from last transplant, my runoff PH is very low, 5,2-5,3.(In the smaller pot the runoff PH was always 5,9-6,1) But before that the growing was also very slow and the plant was always pale green. I used to spray them with Bio Nova Spray mix (which is kelp based product) and this is always helped. So i am thinking it is Mg def (or calmag).[/FONT]

[FONT="]What do you think what am i doing wrong?[/FONT]
[FONT="]
[/FONT]
[FONT="]In my opinion possible cases:[/FONT]
[FONT="]My goal is to transplant them into 1 gallon fabric pot, and switch to drip irrigation (i made a system ala PICO) and feed multiple times a day. But now i am far away from this.[/FONT]

[/FONT]
[FONT="]In my opinion possible cases:[/FONT]
- [FONT="]watering schedule or freqvency or amount[/FONT]
- [FONT="]nutritient problem[/FONT]
- [FONT="]Calmag problem (maybe mix RO with tap water?)[/FONT]
