Week 7 of flower, is this a nute deficiemcy or light burn? Or could it be something else? Sent from my Pixel 2 XL using Tapatalk
My guess ph first. Than during first part of flower they are really hungry. Looks like she needs cal mag too. I would cut nitro give her bloom nutes pk boosters and calmag and molasses Sent from my SM-G935T using Tapatalk
Been feeding them at 5.6-5.8 but it was a bit low 2 weeks ago. Feeding them exactly that but didnt want to add calmag as it had nitro, will try doing that. Cheers. Sent from my Pixel 2 XL using Tapatalk
I thought I saw calcium deficiency too but hard to tell with the led light on. I use calimagic as my cal mag because it has the least N in the calmag supplements. Are you in coco? If so, what is runoff ph?
Its coco, ph is usually at 5.6-5.8 when i feed them. Runoff is about 6ish. Sent from my Pixel 2 XL using Tapatalk
They are in coco, runoff is 6ish. Ive been tising calimagic too. I thought the leaves looked abit dark green so i cut it out. Will try adding it in the next feed . Sent from my Pixel 2 XL using Tapatalk
Raise your ph of feed to 6.1 for the remainder of flower. I’ve found the lower ph is fine for veg, but as the plants start taking in nutrients at the flowering stage much quicker, the higher ph makes more calcium available. 6.0 is right on the cusp of calcium uptake on the low end and phosphorus uptake on the high end of ph.
The dark green leaves with the sheen like appearance makes me feel like this is nitrogen tox. Your leaves aren't supposed to shine like that. Sent from my iPhone using Grasscity Forum
Do you have purple stems are the viens in the leaf not the. Normal look its cal-mag either way I would FLUSH first let dry and then add something you might be in a lockout bc to much nutes in coco Sent from my SM-G950U using Tapatalk
Yeah, but there is 1-0-0 ratio npk in calimagic im quite sure. Sent from my Pixel 2 XL using Tapatalk
I agree, but i cut out calmag and everthing else is bloom nutes, bloom additives etc... Ill take a second look at what im feeding... Sent from my Pixel 2 XL using Tapatalk
Fair enough then, ill try flushing it before the next feed tommorow. Feed at 6.1 ph but maybe half strength cal-mag? Sent from my Pixel 2 XL using Tapatalk
This is what the stems look like, best i could do at this time with the lights... Purpleish stems. Sent from my Pixel 2 XL using Tapatalk
Are you still feeding grow nutrients? That'd be where I'd try cutting the nitrogen. Coco grows require more cal/mag than other mediums.
