Need a little help

[The Irishman]

Hey started noticing light green Mark's on the leaves looking like its starting from the inner part of the leaf if that makes sense. I guessed it might have been a deficiency since i keep my ec quite low

Growing in coco using 1 week of flower

Below was what I was feeding them

Background EC- 0.1
150L reservoir

Hammerhead Pk - 37.5ml/l
Canna coco a - 120ml
Canna coco b - 120ml

Ec - 0.6
Ph - 6.0

I have upped the nutes the past 2 days and fed them the following hoping this will help

Hammerhead pk - 37.5ml
Canna coco a - 170ml
Canna coco b - 170ml

Ec -0.9
Ph - 6.0

Thought I would post here since I genuinely dont know what the problem is, it was just a guess that they were being under fed. Any help is greatly appreciated

I have 3 identical plants all dropped and popped at the same time and have a similar issue with just one of them:-





Not very helpful but the other two being feed the same stuff in the same environment seem ok





It might just be genenics or that as I suspect the one I have that is a little green is either:-

• The one that got the seed stuck to it's head
• The one I dropped while transplanting
• Both of the above ;OI)

Something is better than nothing and I am sure the more knowledgeable peeps will let us both know what is wrong ;o)

Reminds me of a plant I had with Iron deficiency

Does look like possible iron lockout but shouldn't be in that ph range, how longs it been since you last calibrated your ph meter?

This will help as the plants are hungry. Once flipped the plants go into overdrive they can double treble their size in 2-3 weeks so will need that extra feed. O.6 EC was pretty low in veg tbh prob just on the limit to sustain the plants.

Minty i see nothing wrong with your plants they look happy.

What week are you in flower or are you still in veg?

I second the notion to calibrate your PH pen. Or go buy another one to check yours against.

It's also interesting that your background EC is 0.1. That's very soft! My RO water ain't far off that. IMO you're underfeeding. What you're seeing is iron def. Fe is immobile and you get that yellowing pattern starting at the growing tips, working it's way out from the center of the leaf. I would look to give them a foliar feed of something with iron chelate and up your EC.

Cheers kbag yeah they do look little better after upping the feed. Gonna up it again in a day or so when the reservoir is done and take it to 1.1/1.2

1st week of flower mate.i use a blu lab guardian ph/ec meter and calibrate it every 2 or 3 weeks when it flashes to tell me so. I calibrated the meter just before flower mate
