Can't figure this Def out, please help

Not sure what's going on with my two plants.

Here's some details:

4x2 tent
600w mh bulb
Gh flora nutes
1050ppm
Ph 5.8
Tap water: by itself is 241ppm and around 7 ph
Seeds are greenhouse trainwreck

This def just started this week right before I transplanted and then cut a little of the bottom leaves off.

This was also the first week of recommended veg nute strength. I flushed today with 6.0 ph tap water to make sure there was no buildup, and so far there hasn't been any change in the last 11hours. Before this week I was using a 481ppm strength solution.

Maybe it was too strong? They've been growing for a little over a month now, and have been topped and some what lollipopped.

Here's the pics:

I do have to add that I switched from jacks classics to the gh flora series last week, because I couldn't figure out which jacks to use and how much of it to use. I have all 3 jacks, the bloom booster, orchid veg stuff and the all purpose stuff.

I was using only the veg jacks nutes and at their recommended dose plus cal mag and the ppm was only at around 350.

1400 to 1000 ppm is a lot for the plants to take in just a weeks notice, i'd down that by 200 ppm maybe... leaf size looks really good other wise!

They look pretty healthy, what makes you think there is a problem. The first pic looks like it could be mag def. I can't tell but they look like they have a bluish tint which could be from phosphorus def.

here hope this helps yaView attachment 1904233

Throw out gh flora nutes ,especially if it's a 1bottle solution...it causes nute lockups like crazy.just water your plants with some trace elements for 3 weeks, or transplant asap

to me it looks like your not allowing them to dry and much as they would like and or nute burn cause the tips of the leaves are curling under almost like you have a little to much nutes maybe just skip and feeding? it could also be salt build up but it doesnt look bad tho. I would just let her be and see how she does if it gets worse its not over watering then maybe flush her that would fix nute burn and salt build up that would kill two joint with one stoner

I can spot a cal def for sure, but i would say that you also have nute lockout. I would not use anything by GH aside from there PH products.

Thanks for the fast responses, I'll feed with just ph'd water one more time next feed and then I'll slowly nute again. Thanks again.

Ok bro the ph is too low causing the lockout of nutes. Make sure you water/feed with 6.5 ph .
Take soil reading and runoff. Look at this chart and with the ph at 5.8 (prob lower) you can see your majorly locking out P, Mg and Ca and lesser extent N and K.

Hard to tell exactly what could be wrong from your pics, but this link is to a great thread about deficiencies and abundances. Check it out, hope this helps. Good luck.
