Dernière semaine de croissance.
Changement de solution fait le dimanche 22/11 car le ph commençait à descendre en dessous de 6.2 et cela faisait 1 semaine que j'avais fais le précèdent changement.
Le PH lors du changement était de 6,8. Il est monté jusqu'à 7.5 mais je laisse le filtre faire son oeuvre. Il est actuellement à 7.1 et continue de descendre naturellement.
carence en fer. Ajout d'une dose supplémentaire de Sensi CalMg
Edit au 25 :
Malheureusement ce que je sentais venir est arrivé, saturation en N.
Le Ph et l'EC continuaient de baisser tous les deux. Les parties basses des plantes étant sombre et ayant une carence en fer sur la partie haute (puisque élément mobile), j'en ai déduit que c'était une carence en fer induite par une surfertilisation en N. J'étais à un EC de 1, je suis revenu à 0,8 le mardi 25 au soir. La bioponie est très capricieuse au niveau de l'azote. Le mercredi 26 le ph remonte ce qui signifie qu'on a stopé le processus de dégradation du N. Je devrais changer la solution mais je dois passer bientôt en flo donc j'ai enlevé de l'eau et rajouter, histoire de tenir jusqu'au prochain changement de solution qui est prévu samedi sauf si la situation dégénere de nouveau avec le PH.
Last week of growth.
Change of solution made on sunday 22/11 because the ph was starting to drop below 6.2 and it's been 1 week since I made the previous change.
The PH at the time of the change was 6.8. It went up to 7.5 but I let the filter do its job. It is currently at 7.1 and continues to drop naturally.
iron deficiency. Addition of an extra dose of Sensi CalMg
Last update :
Unfortunately what I felt was coming has happened, N saturation.
Ph and EC both continued to drop. As the lower parts of the plants were dark and iron deficient (on top because is mobil nutrient), I deduced that it was an iron deficiency induced by N overfertilization. I was at an EC of 1, I came back to 0.8 on Tuesday evening the 25th. Biopony is very capricious in terms of nitrogen. On Wednesday the 26th the ph goes up which means that we stopped the N degradation process. I should change the solution but I have to float soon so I removed some water and added more, to hold until the next change of solution which is planned for Saturday unless the situation degenerates again with the PH.
Ultima semana de crecimiento.
Cambio de solución hecho el domingo 22/11 porque el ph empezaba a bajar de 6.2 y ha pasado 1 semana desde que hice el cambio anterior.
El PH en el momento del cambio era de 6,8. Subió a 7.5 pero dejé que el filtro hiciera su trabajo. Actualmente está en 7.1 y sigue bajando naturalmente.
deficiencia de hierro. Adición de una dosis extra de Sensi CalMg
Ultima hora :
Desafortunadamente lo que sentí que venía, la saturación de N.
El pH y la EC continuaron bajando. Como las partes inferiores de las plantas eran oscuras y con deficiencia de hierro, deduje que se trataba de una deficiencia de hierro inducida por la sobrefertilización de N. Estaba en un EC de 1, volví a 0.8 el martes 25 por la noche. La bioponía es muy caprichosa en términos de nitrógeno. El miércoles 26 el PH sube, lo que significa que detuvimos el proceso de degradación del N. Debería cambiar la solución pero tengo que flotar pronto así que saqué un poco de agua y añadí más, para mantenerlo hasta el próximo cambio de solución que está previsto para el sábado a menos que la situación degenere de nuevo con el PH.
@cannavici, Hi! I was doing some reading on tips on grow lights such as this the Lumatek Pro powerful and efficient..! I learned that more or less lights in this quality they are really niched for commercial growing. If i understand my biology all plants need Co2 for process in photosynthesis and. What i learned was that a lot of homegrowers with powerful lights like the pro version get nutrient deficiency warnings probably among other things when it's really a issue of light intensity due to the plant can't handle the intensity it's given. So in nature there is a constant exchange of O2 Co2 but not in the same way as the grow room. I assume if one lacks Co2-the exchange will be less and the grow will not have reached it's full potential in yield and potency?
So in Commercial Setups they use Co2 tanks to counter that ever happening. Knowing your PPFD and DLI knowledge might change every aspect on how one grows! People might know but maybe not..! I have learned that simply getting that extra Co2 with mushroom bags or cannisters helps a lot to gain quality and to counter Super Power LEDs problems but i know that this is not a must at all to grow! Bless!
@cannavici, nope, works a little because I had it but it was N excess for my light intensity. If you have any excess you can put your light on 100%. In my case it work, I have no more deficiency
