Plant suffered of poor quality water, problems of transpiration and nutrients absorption due to pH unbalanced values, low humidity level, both light and ventilation intensity excess.
Humidity is under control: stabilised between 45% and 50% continuously.
pH has been fixed to 6.0 in all H2O solutions.
Exhaust fan has been equipped of a rotative knob control in order to settle power: once desired humidity level is overpassed ventilation can be returned to max speed in order to maintain 24,5 Celsius degrees.
LED light cycle 24/0 TOTAL AGRO at maximum intensity has been abandoned for energy and its cost savings purpose in relation with the final scope and entropy reduction effectiveness :
Main+ 100 Blue+ 100 Red+ 100
LED Light Spectrum has been settled in order to give a natural Sun Dawn/Sunset effect maintaining the 24/0 cycle:

Note:
ORTOLED SERIE K is intrinsically provided of Sunrise/Sunset function which enables a smooth, uniform and gradual variation of light intensity during time without generating any kind of shock from sudden switching on or off, or changes in power and spectrum value.
Blue light parameter overwhelms in this stage in order to encourage vegetative growth, compactness, and bushiness and photomorphogenesis, its development, including leaf expansion, stem elongation, and overall plant architecture.
Decreased light intensity during night cycle should help regulate phototropism and reduce light stress.
The plant well reacted to the care it received and the measures put in place, which given the visible critical health condition, were drastic and extreme.
Possible combination of over feeding, overwatering and excess of light, responding to stress to be identified, on the basis of following visible symptoms :
- leaves have turned thick, fat, dark deep green;
- leaves start curling;
- leaves hint a deep yellow hue;
- new leaves are born with light green and yellow tips;
- leaves report burnings such as fresh black spots which turn into dry brown spots;
- 1 leaf at the third node is born with 4 tips, the second one is a 5 tips leaf correctly.
Additional considerations to be uploaded asap regarding :
- Biochar pH 8,5;
- Biochar nutrients absorption and retention capacity in relation with organic growing;
- Biochar and Coco Coir micro and macro nutrients binding capacity;
- moon effect during plant life cycle;
- huge vitality has been noticed during crescent moon appearance;
- plant is asking for more and more feeding;
- growing will be abandoned for no more than 96 hours therefore a self irrigating cotton rope wick system has been implemented.

@cannasaxx, Hi!
Thanks , the plant gets wet under those ropes and asks for more and more! The project consists of growing in a bigger pot using the same tent adopting SCROG or JOG techniques for better result.
@se7en, Hi! Thanks for the message , really appreciated! In micro growing it is extremely difficult to maintain stability as the plant transits from low activity stages to strong sudden development phase , as well we should consider that roots once expanded have reduced space. The problem could be related to Calcium Magnesium low absorption due to the catalization activity performed by Biochar and Coco Coir in medium: adding strong quantities of CalMag supplement (within the limit of over feeding) helped, making healthier green leaves. Check new pics you will see how adding blooming PK nutrients in combination with Calcium Magnesium gave a beautiful green healthy colour ! pH is under control and stabilised both on soil and in nutrients solution to 6.0 sharp.
The new self feeding system alternated with 2 days of drought helps stabilising the flower growth on the branches where the plant is naturally taking what is missing from excessive fan leaves. In the new pictures you can see how defoliation, for example, has been adopted on leaves from which plant totally absorbed nutrients, with positive results on flowers and related fan leaves.
