Flowering loosing color

[eps]

My plant that is in its 3rd/4th week of flowering is loosing color in its upper leaves. Don't they usually consume their lower leaves first?

Hydroponic drip reuse system. I change its water probably every 3 or so days. Does it need more nutes more frequently?

that is nute burn or underwatering or something... can't tell with the lighting.

your leaves don't look too healthy... skinny, curled, dry looking. Check humidity / temps

Thanks. I think they get a fair bit of water, like 15mins every 2 hrs or something. Nutes are exactly used as recommenced.

The burnt tips are from a previous falling light incident.

Anyone else?

Any more ideas now that I have better pictures?

Anyone thinking something like a mag deficiency or something?

Should I try more nutrients?

did you go by what it said on the bottle of nutrients?

Yes. 3ml/L of A+B. I do weekly changes and when I top it up, I don't add nutrients.

yeah its always a good idea to give plants a fraction of what it says on the container, for my plants I'm feeding a quarter solution of nsr greenleaves growjuice, when it gets a little further in its growth, I'll give it half of what the bottle says. not 100 percent but its a good rule of thumb.

Epson Salts bro. Had the same thing happening for the longest time. Get some epson salts at your local hydro store i add 1TSP per gallon make sure u pre mix it before you put it in your rez to dissolve it. You can try using it as a foliage spray that would probably work a little bit faster but hmm i dunno you already got nugs growing out. Well anyways try it out let me know. Also you wouldn't happen to be growing with liquid lumen s??

No liquid lumen s. Just my canna nutes.

Do I need to start applying as soon as I see the yellowing of leaves? Anyone else care to second this?

Thanks heaps

Ahh liquid lumens is a reflector Canna nutes been using then over a year now dam good nutes. Used AN before bout 2 years before canna and i just couldn't be happier with the switch. But they do lack a lack on micro nuts like calcium and magnesium. I use A Calcium additive made by plant amp ( i think thats the company name) and i use epson salts for the magnesium and sulfur. Haven t had any discoloring of leafs for months now and i run a SOG 25 plant every 3 weeks Very similar to the one Al B. Fuct owns.

Thanks so much for the replys! So I plan to add some epson salts. Do you think it will make a difference because of the stage i am at?

What do you think about adding Blackstrap Molasses now instead?
