what is this?

[buzzkillz]

3 GG#4 auto's 4 weeks old..1 is like 4 days behind ..... 2 are in fox farm ocean, and one in black magic coco. using general organics, last watered tuesday of what was recomended on box but at half dose. temps 70-80 humidity 50-65, 24 hour light from seed


the tips turning yellow some are red. some of the leafs look kinda droopy. ive looked at charts and im not sure if they have to much of something or if they are lacking something. also there are red spots on some leafs too i thought its water from to much humidity then light burnt it?


another thing is training, when should i pull them down and let the bottom ones grow?. i already trained for a bit but untied them to just let them grow also i kind messed up some of the leafs. any help would be great i hope i dont mess these up

the leaf tip burn is too much N. Dropping looks like they need a drink. The other yellow on leaf looks like nute splash

 

[buzzkillz]

what would you recommend? just ph 6.4 water? or give them everything else but N

 

[umbra]

yes always ph after adding nutes to water

 

[buzzkillz]

no i mean should i just give them water this time? or give them everything but N, i always ph

Give them a flush with straight water.
Let drain and go back to very lite nutes next time.

the nute burn looks pretty minor to me. you could just skip a feeding or two also. you are early in veg so maybe just back off on feeding full strength too and see how they respond.

thanks for the help guys. ill just stick to ph water for the next 2 or 3 then slowly up nutes 1/4 then 1/2 strength. id rather go to little then to much, besides theres still alot of stuff in the foxfarm i guess i just started to push them a little to hard.

The foxfarm can be a little hot for seedlings

 

[STIGGY]

I agree with all
Not feedin full strength as per instruction on bottle?
Start out low and slow

 

[key2life]

I flush my solo cups of Fox Farms 2 or 3 times prior and then the seedlings love it

i have alternating nodes now and hairs going but its still showing signs of stress, cant tell if this is N toxicity still or cuz i need P in the bloom nutes, i am running fox farm ocean and am 30 days since they got transplanted the that pot, temps are 70-80 but been shooting for 80 humidity 50-60% but been shooting for low 50's high 40's. CO2 is steady 800-but will go up to 1400. been doing nothing but ph water 6.4 since i flashed them last week, can someone help me with what is causing this

 

[oldfogey8]

I’d start feeding lightly. Make sure you have a good wet/dry cycle too. A knuckle or two deep should feel dry between waterings.

heres some more pics. some of the hairs are turning red

 

[oldfogey8]

Seeing those pics, the new growth looks like it is suffering the same issue as your older growth. Maybe the fox farm is still too ‘hot’ for your plants. Is your ph meter calibrated? Overwatering maybe too. You don’t let the plants sit in the runoff, do you?

 

[buzzkillz]

ph is good, i have a good meter. when i water i drain the water out of the trey right away, may have overwatered as i am i newbie,

 

[thegloman]

Most newbies over water at 1st.
It natural to want to fuss over your babies and sometimes less is more.
Good rule of thumb is after a good watering, let the grow medium/dirt dry out at LEAST 1" better with 2" deep from surface.
Letting it dry out helps prevent gnats and helps oxygen get to your roots. If roots stay Wet they can dround and get fungus.

1 way to know if plants needs water, … pick it up.

Clones or from seed?

edit: Oh I see they are from seed (autos)

Never mind. lol

 

[buzzkillz]

Yea I think this run probably won't yield much but I've learned alot and my next one will be way better


Autos are so touchy but a good way to learn from your mistakes
