Help Me Diagnose this


#1

This plant has always kind of been a runt but I’m not giving up on her. Could you please tell me what the leaves are saying. From research I think it’s a cal/mag issue or maybe nute burn.


#2

need more info pls. don’t overfeed your baby, she’s young…
npk?
pH?


#3

Plant is a little over 3 weeks and i recently repotted into FFOC. Ph is within range. Not sure on NPK. I’m feeding 1/4 strength every 3rd day. No other plants are showing problems.


#4

ok looks for me like…pH issue
i has the same issue with higher pH
oh and i forgot something…don’t feed with cold water! 20-22°C water temps are ok


#5

Ok thanks. It’s just strange that the other plants aren’t showing the same issues. I’ll order some ph supplies today. To bad no place around here sells it


#6

another plants? you mean another strains or the same? some indica strains need more nutriens at lower pH as Sativas


#7

Feeding every third day in your soil has potential to overload your young plant with nutes. You are usually good for 2-3 months with nutrient charge of ffof


#8

yeap. 1x a week is enough
just buy this one and you are safeSX425

I will say, the bottom leaves showed it a week or so ago and the new growth was fine. I fed yesterday and a spot showed on the unaffected leaves. I’ll back off on the nutes and see if it helps. I figured my noob ass was a little over zealous. They are all NL photos. Based on the size and age of the plant i probably over fed. Hopefully the plant will recover or not die before my meter shows up. Thanks all


#10

yes. stop feeding for a while (week)
give her only watter (pH 6.4- 6.5) and check every morning. in 3-4 days she will be ok
good luck. keep us updated


#11

It really sucks that nonplace around me sells these supplies. Is there anything I can use at home to adjust PH if needed??


#12

yes. you can use lemon concentrate as natural pH downCitrovin-Zitronenkonzentrat-200-ml
u can also flush your plant with Distilled water


#13

Could you describe the flush process?? Sorry I’m a greenhorn


#14

size of your pot? don’t worry, it’s a easy process…
3 gallons of water per gallon of soil…flush SLOWLY, don’t let the water run down the sides
Allow plants to dry out and breath for a few days, till soil is dry one-half inch below surface.


#15

5 gallon pot. I’ve got plenty of water. From what I understand, water from my dehumidifier is distilled. Also, I have a RO unit I can use


#16

water from dehumidifier should be fine. 10 gals for 5 gals pot are fine for flushing
i have 20 gal pot so i need lot of water.
make sure, after flushing allow plants to dry out for about 5 days and start again with correct pH.
don’t give her to much nutes. 1x a week is enough.
1/4 strengh is to much.

Strongly suggest you start at 20% of mfg feed schedule. Then adjust as needed.


#18

I’m dropping nutes completely until they improve or get bigger


#19

Flushed the effected plant and will monitor the patient. Did see a hint of it on the tips of plant #1 also but nothing like plant 4. Thanks for all the advice guys and helping me with a good grow.


#20

This issue continued to spread. I’ve determined that it is most likely rust so I removed the effected leaves and am going to treat with a fungicide. Hopefully the plant makes it thru. There is still lots of new growth at the nodes.
