Help I’m a newby

hey guys
So I’m new here. This is my second grow. First one was a compete screw up. And don’t want same thing to happen to my new one.
I’m growing 5 shiskaberry and 5 mr hide. I’m 4weeks from seedling.
I see yellowing in the tips of the new grow in some. And yellowing of the full leaf in some.
Grow room is 2.4mx 2m.
2 600 watts Hps
Smart pot 1 gallon ready to transplant in 3 gallon

Using bio Bizz grow and heaven at the moment. Light doses. Soil ph is at 6

I posted some pics
Please help

The burnt tips of photos 1, 3 & 4 says overfeed (at least once). Can you take photos in natural light? In some ways it looks like mixed signals.

The soil looks dry. How do you water? Do you pour enough for runoff? (A thorough drench, then let it dry?).

Hello Tnx for the reply I usually do runoff watering weekly.

Is that as high as you can get them? I'm going with too much light on this one. But I'm left wondering if the soil has nutrients already, how often are you watering? Do you add nutrients every time you water?

Really strange thing is that your plants have a structure most that most growers only dream of, so you were doing well until your leaves turned yellow. Some thing you changed lately maybe?

I started adding nutes with every water according to what the bio Bizz chart says. But I’m applying half the quantities they say

Since your showing yellow on bottom ( nitrogen issues )

I would raise your N intake and as a suggest so you don’t lose your bottom and give the whole plant some N ASAP by spraying a nitrogen based /bacteria . You don’t want to lose your bottom leafs or have the plant have to wait for the whole process of intake from roots when you can def help em.


what I would suggest in the future is look into primordial solutions seagreen and rootamentary foliar & drench ( all their products rock but for a start and your issues these would def help)

Is bio grow from biobizz good enough.
It’s should be high and N and it’s organic
 
Everyone seems to be steering you in the right direction, although something has been left out. It looks like you are having tips yellowing even in the new growth in a few pictures. This could be expressing zinc, moly, or magnese deficiencies as well, which could be the result of a few different things. If adding N alone doesnt help, Azomite top dress would be the next step I take, just cover all the trace minerals at once. You wont know exactly which micro it is, but you will have a decent search grid to start with. PH and salt buildup can cause these deficiencies as well! Hope this helps!
