Confused need help plz

Hi all need some help some help with this fan leaf problem what def could it be. This pic was take half way up the plant had a few lower fan leaves like this.
Growing in soil.ph
6.5
Temps 25.5 lights on 21 lights off
3 and half weeks in to flowering.
Strain pineapple chunk.
Nuts jungle juice bloom+ molasses
Rh lights on 30-50
Rh lights off 50-56

Watered today but was thinking when lights come on to give her a flush.
Any help would be great.

Hi mate you probably didn't get a reply because you have you purple lights on when there is a thread that says turn ur hps n should mention bout the leds because no one can actually see what's going on.. Pull your plant into a room with good lighting and take another picture see we can see the leaf and maybe whole plant too, or here is a chart I found handy
Hope it helps and hope to see more pictures so you can get accurate advice buddy.

Im gonna say to throw a little epsom salt into your feeding regimen.

Thanks for the help will pull her out when the lights on. A flush would not hurt her would it? Even the I waterd her yesterday.
Also when I do the flush could I add the Epsom salt to the last bottle of water that will go through her? Or would I be over doing it with espom salt any help would be great thanks

Flush by chemical or leech by watering it I don't understand your flush?, and why do wanna flush at week three?

Good point maybe I should give some water with espom salt in then the lights come. Then keep an eye on the leafs to see if it improves.
Labs Dexter could I still use the molasses with the Epsom salt mate?

I would do sperate watering sweet an sour lol I'm not sure I wouldnt go well but once again I'm not a pro.. Leave the flushing till week 6 or 7 but when you water make sure you have a really good run off, I had problems before but after making sure I waterd properly an achieved 20% to 30% run off and touch wood less issues in me room. Hope it helps mate and try and save that chart I sent ya earlier it's good to keep by good info on it and good luck

Will do that mate that chart is really good it explains it better than his old book. The lights are due on in less than a hour il give her a good watering with the espom salt. Another thing is I never really waterd till there's a run of I use a soil moister prob may be that's my problem not giveing enough water. Just worried about over watering

Calcium and magnesium, are you adding any or have you added any yet?

Added dolomite lime when mixing the soil. I have some espom salt and some dolomite lime but no nuts that contain calcium

The plants suck back both calcium and magnesium. I run 100-150 ppm of a liquid calmag supplement at every water. Liquid calmag is mixed at the right ratio and is faster acting than powders. Chances are pretty good you need it since you havent ran either besides a soil ammendment. Hydro store or amazon, 18 bucks a quart, itll last you a long time.

Haven't go no hydro shops near where I live was thinking i might be wrong could I use the espom salt in watering and put some dolomite lime on top of the soil before I water. Just a thought??

3-4 Crushed powdered eggshells clean the egg shells put them in the oven for 5mins the crush grind & beat them, poke a hole with a pencil in the soil in put the powder in the lightly water

Calcium is what the def is then. I thought I would have to flush the girl thanks for putting me right.
