lol if this was nute burn i would have 50 ppl telling me it.....
Is the runoff 5.7 or the water you're adding 5.7?pro-mix, 5.7 ph, big grow. same as the guy i got it from . only one of 3 that have it.
Purple or red petioles are a sign of a Nitrogen deficiency. My guess is they have been in the promix only for a short time. If this is the case then give them a bit more time to get use to their new home. If they have been in the promix for sometime then you may want to up the Grow Big a bit.
Thats why I asked how long its been its new medium. Also as mentioned earlier the pics may be a bit deceiving if they where takes under a LED. I drew my conclusion by the looks of the entire petiole. Also some plants are particular phenos will present reds and purples when N deficient mainly in the veins and petioles. I still think they are just getting use to their new homes and just need a bit of time to adjust before tking any drastic measures.Forgive me, I've never seen nitro def do this. In all cases I've seen, it was simply a yellowing throughout the leaf. Perhaps there's something else working in concert with a nitro deficiency?
So when you posted 'Big Grow' do you mean 'Grow Big'? Or maybe Big Bloom? Which ever have you used any, and if so, how much?and got put in the pro-mix about 1.5-2 weeks i think

And I should have used the phrase 'can be' instead of 'is'. My bad...
Cheers.......Well spoken...well for me, first time, and I certainly haven't seen everything. Cheers.
