Defiency problems. Confirmation required.

hi there..

so this is round 2... learned alot during round 1.

Ph is stable at 6.4 last feed was 1/2str (600ppm)
Feeding with advanced nutes (Micro/Grow/Bloom)
and some calmag also 1 tsp mollasses per gallon.
doing a water/feed cycle.
Plants have just been moved over to flower 5 days ago.
They were topped and Flushed then 3 days later transplanted that was 1 week before the switch..

All plants are showing these signs on the bottem leaves working there way upward this to me says its a mobile element that the plant is not having enough of.
Mainly Phosphorous

So what steps should i take to resolve this problem just up the dosage of nutes?
Mabey tweek the dosage to have more P in it?



On a sidenote Does anyone know a good Feeding sheduale with PPM included?
(edit) i know each strain will react differently to Dosages but i need a good starting point.

If the stem is purple Its Nitrogen

but my very bottom leafs or as I call them shock pads do the same thing but nothing to worry about for me but a friend told me it i could have been the bottom leafs not getting enough light which was true for me

check out my grow in my sig

its not N def. purple stems is also a sign of P def. and not N def

Also the leaves are dropping off after a day or 2 of changing color.

Are your fan leaves getting a purple hue to them maybe spotting or any other odd coloration, like not a consistent green?

Flush your medium with a low ppm just your cal mag if using r/o and personally i would back off on the mollasses until they get a little bigger and more established before hitting them with nutes. Especially considering you just transplanted, did you feed with your transplant? Or just water meaning water and cal mag only, then feed after the first initial watering?

All the upper foilage is nice and green and consistant.

To Beachgreens
All the plants have been flushed 8 days ago when they were topped.
3 days later i transplanted and watered (water +calmg to ph6.4)
since then they have only been fed once with a low str (600ppm) mixture.
i highly dout another flush is the solution.

if anything i think they want more....

After re reading your walkthrough again, to me personally ive never used mollasses. Cant say id reccommend it with a clear concious. If your looking to add something like that i would recommend is Bud Candy half strength. If your plants arent getting a specific nutrient that is in demand the only way i would say to guarantee the delivery of that specific nutrient would be to water a heavy amount with a bloom nute rated in a high p ratio, and not worry about the k just yet. Mj preffers to have more k towards the end of the flowering cycle to put on weight and mass. Concentrate more on the p for right now. Thats my 2 cents. O and stay on top of cal mag religiously. Not having it can cause alot of issues if using pure 0 ppm r/o. Hope this help good luck to you.

Happy growing!!

Edit: Also advanced nutrients tells you that you will not need cal mag if using their base nutrients they contain plenty enough of both elements.
