11 finger leaves ?? And see some colour change in 5th week bloom

Es fehlt Phosphor .... und die Lampe ist zu dicht an den Pflanzen.

Thanks I done a couple off days flush PH water all seems good now think it might have been slight over feed or build up in the coco thanks all your help guys I will try keep my diary updated

Just wanted to mention that I’ve had 15-16 finger leaves in my current grow. Probably genetics.

Nothing wrong with 11 fingers, I have had plants with 13 fingers! Otherwise what Roberts wrote is good advice.

It is a ph imbalance in the coco. I am a experienced coco grower. Your plant is calling for lots of potassium and phosphorus. If you did not account for it the ph of your coco has likely risen about a good range causing a lock out. Which in turn is making plant fade.

little early for a fad, but if you are in a soilless mix it doesn't take much to change this... adjust formula, add a little more N and give a littel extra runoff for next couple fertigations... bam.. new concentration in substrate achieved. before oyu do that... are the leaves only pale unde the grow lights? make sure in normal lighting they aren't just a little on pale side... grow lights play tricks. e.g. your #2 pic here doens't look faded much -- shaded areas look fine.
