need some help please take a look pics

I'm having a problem with the leafs making a claw I'm not sure if its a water problem or nut. any help please!

pics are a bit small but with yellowing leaves so early in development i would sy nute. whats your ppm ph and ec?

light cycle 18-6
water 15 min every 3h while lights are on.
temp. 67-75
my room mate did the mixture of nut but i pulled it this morning washed the res and turned off the lights and water for 24 hours. they are babies should they even have nut in the water yet or just a balanced ph

you know you can just leave it on all the time right?

i had them on for the first 48 hours and they seemed to wilt to overwatering. but the water got warm so maby that was the only problem! thank you for your advice ill keep reading

I run a filthyfletch tub just like that one. I run the water pump 24/7 with no issues. Overwater? The roots should be in the water. What are you using for bubbles and what is the Ph in there?

also the strength of your nutes should be very very weak as you are hydro i think u need to use nutes as your medium looks like pebbles. are you using rockwool cubes or anything else ???? ph should be maintained around 5.8 with a little fluctuation either way.

Any bugs? Look real close. no
Any other pertinent info? when i found them 48 hours ago burning i cleaned res and turned off lights and water for 24 hours.

I'm not really sure what your problem is but, I can tell you this. I start in rockwool, my tub is the same only 2 stones, I use pebbles, I have T5's, my Ph is a tad higher but, I don't think that's the problem. The only thing that I do differently is I run the water pump 24/7 and I have never seen what you are experiencing. Is that the answer? I really don't know but, good luck.

Nitrogean or phos def flush and clean the unit then follow with some good nutrients.Also cut of the leaves that are yellow there time is up if these are clones this sometimes happens to the bottom leaves so don't worry has long has the ph is checked after nutreints are added and set the around 5.5/6.0.

...I'd give them a 1/4 strength solution using any micro, grow, bloom....see how they act for a week, slowly raise the ppm of your fertz as your plants age.

Do you have any kind of ec/ppm/tds meter?

Are you using any nutrients? Of what and much?

I'm not sure but I suspect that this question is for me. I use GH Maxigrow to veg, I start at 1/4 strength and build up from there.

appreciate the advice i think the nut burn just stunted them.... the roots are just breaking the bottom of the basket all the damaged leaves are shirking and falling off new growth is strong! thanks for your advice

anyone else any help I can get! thank you

no no nut yet...... starting in 2 days what are your suggestions keep in mind areo
