Chronic Turning Light Green

The bright green of native chlorophyll in plants is determined by the presence of a central magnesium atom in a large porphyrin ring. While nitrogen is also important for plant growth, it is not directly responsible for chlorophyll's green color; it is a component of the chlorophyll molecule but not the central atom. The resonant frequency of pure magnesium is 4,620 Hz, If a guitar string is plucked and we hear a sound, it is not too difficult for the human mind to associate this sound with the vibration of the guitar string. With color, it is quite different. It is difficult for us to conceive that the color of a substance is not an inherent property of the substance itself, but an indication picked up by our senses of that substance's ability to absorb or reflect the light which happens to be shining on it at that moment. Neither the matter nor the light is colored. What happens is that the brain learns to differentiate between the frequencies reflected or transmitted by the substance the eyes are focused on. The same thing happens with sound.When discussing the "frequency" of magnesium in terms of light, it refers to the wavelength of light emitted or absorbed by magnesium atoms, which is primarily around 285.2nm UV-B. The characteristic frequency of a nitrogen molecule is typically found in the ultraviolet range, with a wavelength of around 75 nanometers (nm).

calcium isnt something it just needs once in a while. you should be providing enough at all times. Calcium deficiency does not cause chlorosis. new growth showing chlorosis is a sign of too much P or K, which often happens with "bloom" formulas of fertilizers that erroneously amp these things up for no scientific reason or evidence-based reasons. If you recently amped up either the last coupel weeks, it's a godo chance that's why new growth is pale. Important to not that leaf symptoms are not discrete. You should have more to go on when making a decision. so many things can cause drooppy foliage. not enough information is given. could be poor watering habits, could be too much light, or could be extremly high or low VPD. Think you can rule out too much light since the droopiest are the lower leaves. VPD-related would be plant wide similar effect, as opposed to any gradient seen. 1) water entire volume of substrate -- no dry pockets. Fully saturating a pot will never cause a problem unless the substrate was poorly constituted, which is a self-inflicted mistake 2) wait for minimum dry back to maintain a healthy rootzone and repeat. if doing something esoteric that deviates from this, stop. If soilless, you also need to get 10% runoff each irrigation. this is supremely important for soilless growing methods. if it's only droopy after an irrigation, you constituted the substrate poorly. Add more perlite or similar next time. muscle through it this time.

It looks like it is not getting enough bloom booster for flowering. Flowering npk ratio is 1-2-3. When there is not enough potassium the tips will get brown but stay straight. There will be discoloration and it will lead to spotting. Potassium is the most important nutrient of the plants life.

*starving* not "statving"

Without a diary and/or a lot more information about what you might be or might not be doing, this question is impossible to answer accurately. pH?? Nutrients?? Substrate?? She could be statving for potassium and/or magnesium. Also many other possibilities depending on what you are actually doing.

How close are your plants to your lights? What is your light intensity set at? This is important because your picture suggests you've got your plants too close to the light source and that less than ideal green is mild bleaching. Here's why - Nitrogen is the primary mineral responsible for the green color of your plants. Nitrogen is also a mobile nutrient. When its nitrogen deficient, it moves nitrogen from lower old growth to feed the new growth at the top. It never starts at the top of your plants. Raise your lights or turn down the intensity. Either one should restore your plants green color on top when you see new growth.

Is the red light an IR strip as it only wants to be on for 90mns at the end of the cycle if I remember,check it out.

HI bud. Do you feed her nutrients regularly or only sporadic? She will want a constant supply of nutrients to get through her grow. As you are growing in pots, these nutrients deplete faster than if you were growing outdoor in nature. If you already feed regularly, it looks like it's time to step up the dosage a little bit. If you are not feeding regularly, it looks like you had better start before she starts canabalizing herself.
