Leaves dying from bottom up

[NEOBUD]

Hello all,

 

I've got 3 week old plants from seed in 100% coco (run to waste) and the bottom leaves of each plant are yellowing then dying, it then moves up to the next set of leaves i thought i might have over fertilized but after a 3 day flush the same keeps happening. The leaves above the ones dying are getting chlorosis near the leaf tips and it's happening again. Sorry my phone aint loading any pics, damn thing. So i think i've narrowed it down to either phosphorous or nitrogen deficiency maybe also Mg (i doubt it though). My question is are there any phosphorous products on the market or should i increase the strength of feeds to make up for it. I'll try to get these pics loaded. Thanks in advance

What strength are you running at now? (e.c.)

 

Which nutrient are you using and what kind of watering regeime are you doing? (how often and how long/much)

Luke we meet again Thanks for the reply, i'm using canna cocoA&B, flairform silica and a drop of superthrive per 10 ltrs at EC 1.3, They're in 3-4 inch net pots and hand waterered daily with approx 350ml of feed increasing. Also the stem and branches are purple and have been for a few weeks. The strain is strawberry cough so im unsure if the purple stem is genetic.

if you intend on keeping them in coco you will want to put them in as big a pot as possible. transplant them asap into a bigger pot and the problem will clear up, it might take a week, but it will clear up the lower death until the plant is rootbound again

No worries WantDa, i have 30 ltr pots which i transfer to when they're sexed so i might have to get some intermediate pots to keep them moving along. Hopefully it will clear up. Cheers mate

dont worry about the purple stems

 

probably due to the cold weather is all
