I have a few plants and been having trouble with them leaves yellowing and crispy well I flushed it 3-4 days ago until was dry last night I used mega crop nutes with PhD spring water and when lights came on the one plant looked worse I know might get worse before it gets better I was told pH problem or Cal-mag I think pH was off as I wasn't c
Phing my water but I did last night I think I'm using promix and happy frog n perlite I was using GENERAL hydroponics organic nutes but wasn't helping might have been ph off but could these plants could be root bound idk here's pics

You can if you know the right members. But yeah my last thread i put in marijuana plant problems is long gone with no replies.

@Cx2H @Dr. Who

Anything to say?

Dr. Who probably wont reply till morning but im betting he'll have plenty to say. Cx2H may not know but im betting he'll have input worth considering

What size pot are you in?

Have you checked the soil ph?

Were you feeding before the problem occured? Whats the npk ratio of the nutes and at what strength have you been feeding?

It looks to me like some kind of overfeeding issue combined with some deficiencies, maybe lockout, but i dont see them often so im going to refrain from saying with any certainty thats what it is.

I see where they get the calcium def but it looks different to me. I could be wrong.

to me it looks like its either or all of the above
and in this order

over watering
magnesium def
calcium def

in that order

make sure you water only when pots are dry

water with Epsom salt 1/2 tsp per gallon and calmag 7mls per gallon 1x

then cut back to Epsom 1/4 tsp per gallon and calmag 4mls per gallon

no additional nutes for now

I wouldn't spray them with anything since the blooms are obvious

What nutrients? You gave brand, I want concentrations of each and everything you add. INCLUDE ANY supplements!

Organic nutrients eh? They tend to play havoc to water or feed pH's.....Whats the pH before you adjust, after mixing the the feed?

Whats the soil?

Looks a lot like the pH is low - blocks P, Ca, Mn. Once you get a blocking action. Related nutrients begin to suffer and get locks due to the loss of their related nutrient not there to help them along....

I suggest you dial back the camera's power some. Have your pics be around 1 MB....... Just nicer for us rural folks on data limits to view...

As far as visiting Plant Problems and the Newbie section... You get tired of people telling you your wrong and that they think it's something it's not and insult you and your family. They then go back to waiting for the answer they want.

As long as that's real soil. You pH to 6.5 in veg and 6.7 in bloom.

If that's Pro-mix or coco....You pH to 5.7 - 6.2.

The repeated action of low pH feed solutions (I'll bet around the mid to low 4's). Overpowered the ability of the soil to self pH anymore...Not allowing the soil to dry enough between watering's, Is just another form of over watering. Looks like that was in play here too.

Your going to have to pH all the feed solutions from now on......Allow the soil to dry out until the pot feels "light" and then water.

Full on solution after you give me answers too....

That's flat out too much P too early! Right along with low N in the bloom mix...IF the files were smaller, I would have opened them...
Up the N to slow the yellowing progression down.......I suspected it but, of course the pic I opened was the one that didn't really look that way - the whole plant pic #2..

Feed the Veg food till week 3 in bloom. During week 3 - 1:1 with the bloom and at week 4 go full on bloom....

Yeah it gets pretty fuxed up with people with predetermined questions that refuse comments that don't fit their notions of ignorance/stubbornness. I've disagreed with people here just on ego and in the end they were correct.

Others were out if their fuxin minds, ca:mg is not the cure-all for everything. ;-)

Long handle spoons work great now.

Root bound. Lack of N. Too much bloom feed too early. Most likely salt build up.

Make sure to mix nutes 1/4 to 1/2 strength to start and to water until good run off to prevent salt build up.

I would flush. I can't believe I just said that. Just run some plain water through them. Up pot. Feed some N and Epsom.
