NEED HELP! How do i fix this??

Hi guys i need all the help i can get and a solution to the problem if available!

so here are my two Sugar Cane girls from Inhouse genetics from seed both in week 1 of flowering.

One of them looks extremely healthy and growing strong,but the other one who is 9 days older from seed is struggling and growth has slowed down and this strange coloring has started to come through,ive tried giving more/less nutes to no avail,while they were both getting exactly the same feed.

Im very confused as to what the issue here is but i expect its a micronutrient issue of some sort as it seems to start from the top of the plants and affects new growth by yelllowing in patches outwards.




any advice as on what to do would be very helpful! Thank you

They don't look too bad. Maybe just give them plain water and see how they respond.

They also might want a little cal-mag, but I'm not a master at diagnosing deficiencies.

Anybody else have any ideas??

carbonated water or grape soda works wonders,at least i've had good luck with it on ill plants

Make sure the container is draining properly. If it were mine I would let the soil get pretty dry and then as mentioned previously use only water for a while. Report back, please.
