Anyone Recognize this symptom?

[NAKEDGARDENER]

New growth is lighter green in color. Some of the leaves on top have some lime green coloring, this just started after feeding nutes only twice in last week, ph is good at 6.5,
wondering could it be a magnesium deficiency, or maybe just not enough light energy for the plant to use all the nutes I’ve been giving, also giving the nutes at half the recommended amounts.

It might be a sulfur deficiency.

The upward curling could be heat or light stress. The lime green could be a result of light burn which in turn can cause deficiencies in lower leaves as well.

K thank you, I will raise lights for a few days and keep and eye on this, but will check on Gwe at sulphur deficiencies to check that. Thanks guys.

I notice that new leaves on my plants are usually lighter and darken as they get bigger.

NAKEDGARDENER My first rule is FLUSH: give those roots a little breather, it usually does wonders for the plant.

I don't think it's twisting as much as it's curling up: https://www.growweedeasy.com/marijuana-symptoms

I'm not exactly sure where, but somewhere on this page there's a reference to leaf curling upwards...??

Thank you alltatup, I’m thinking all the advice I have is fixing this already, I have flushed them tonight, with ph 6 water. 2 hours b4 lights out, going in to open up those canopies and have raised the smaller one up to same height as the other two. I don’t think it’s too much to be concerned about but I am a fussy bugger and I don’t wanna let my lady Penelope s down

NAKEDGARDENER Fussy is good! We see the first signs that something's wrong, and we get to work on it. We nip it in the bud.

Reminds me of this little patch of odd leaves along one stem of one of my plants. IIRC, it developed during the stretch. Don't know what it was but it never spread and those leaves lasted as long as the rest. The rest of that stem was fine, the cola growing above was normal (and the 2 biggest in the harvest, btw) and even the pale green bud in this photo looks normal after drying. Growing in soil, I didn't panic or take any drastic measures. Watch and see.

You made my heart leap just now @ Toripony. Thank you, am about to do a heavy defoliation and then tomorrow going to gently tie down gently onto a minimilastic screen.

[Toripony]

FWIW, I think your plants look great! Healthy looking.

[NAKEDGARDENER]

24 hours after a defoliation, tied down two tops and started a minimal screen with garden ties hooked on , flushed today. Thanks all,

[alltatup]
