Yellow Tips On New Growth!!! Help Me Diagnose!!

Growing autos. This is not my first grow however it is my first grow with autos. Growing indoors. Tent is four and a half by four and a half feet. Under 1000 Watt Light. Five plants inside tent. The plants are now aprox. three weeks and are showing the sex. About two weeks after they came through the soil I gave them their first feeding. I use fox farm soil and fox farm nutes. And when I fed them I gave them seedling strength. The heat is at 74 degrees at all times. And I give them 20 hours of light and 4 hours of dark. Every where I looked up online has said that this is nute burn but I dont feel that is possible when they received the lowest dose they possibly could get. Can someone please help me figure out what the problem is? Will Post Pics Below!

Looks like you need to dial the nutes back a bit !
Sometimes Less is More !!

how can i do that i only fed them once and it was a very low dose for seedlings. I planed on feeding them once a week and it is now over the time to feed them. could it be to low nutes? cause that would make more since. should i feed them or wait or feed them the seedling strength. not sure what to do cause if it is nute burn i dont wanna make it worse and if its low nutes maybe i should feed them a little more

Ur soils hot....don't feed for a week or so more...

You gotta understand you are dealing with a very different canna strain this time round, Ruderalis can and does grow anywhere, and many though cannabis sativia/indica are weeds wait till you see your autos in action, full grown even ...better for you to spend sometime going through the tips and tricks of autos .. https://www.rollitup.org/auto-flowering-strains/652871-advanced-autoflower-training-tips-secrets.html
note the bit where the member mentions the autos tap root etc etc, Ruderalis is quite at home growing on an arctic tundra or an LA beach perhaps even some ice floe on mars one day , chill and cut your nutes, if in doubt you photo-fiend, then foilar feed some nutes, that way you don't burn them at all....lol

ps for this very reason I have advised many to mix in a 50/50 mix of FFOF and perlite, that way photos and autos have a greater control on nute levels

Click to expand...

you kinda said it yourself

" a low dose for seedlings "
the dose i use for seedlings is NONE

and feedings cant really be on a schedule so to speak seeing how you're feeding it when its hungry
if you force feed any thing living it will eventually get sick

so how do I know when to feed them?

when they look hungry if youve grown before then you know the signs
you need to let it use up the nutes in the FFOF
from my experience FFOF is too hot for most auto seedlings and either needs to be cut down or do like i do and put a party cup sized pocket of seed starter or soil from one of my last grows where i plant the seed you're actually lucky the soil didnt burn up the seedling before it got this far you live and learn you know

a few people cut the ffof with happy frog i believe half and half

so i have just been watering so far and dont really see things getting better or worse. except one of my autos is looking really bad and all over the past few days. Can anyone tell what is wrong with it?
All i know is autos are a pain in the ass. Im about to just give up on them. i had no problems with normal grows and im doing everything the same getting sick of it. will post pics is a sec

here they are

I agree with Tek ^ I've also learned that FFOF is to "HOT" for autos. Used it for a couple grows and didn't get good results. Burnt my plants both times. But you live ad you learn... I now mix my own soil. I'm 2 weeks in to a Sweet Mango grow as we speak. If you have any questions on Autos there's a few "Big Doggs" around here that you can talk to...Tek is one of those guys. Don't quote me but I think your looking at a Cal/Mag deficiency. Just google "cannabis deficiencies" and check out some pics my friend. The best of luck to ya

thanks for the reply's everyone. seeing as how you seem to think the soil was to hot what can i do about it now? I dont wanna lose the grow but at the same time they are autos so any problems can mess up everything.
And I do look up problems b4 I post them. Just seems like 90 percent of what i look up someone says something different, on every website that why I post hoping I can get a good answer. (every answer has been helpful).
