First time growing need help!!!

I'm not a soil grower but from your pics, it is a clear case of nutrient deficiency and not a nutrient burn, specifically a Phosphorus deficiency.

I assume you took those pics with the grow lights off. If everything is optimized and it seems like it, your temp is good and you have good lighting then the limiting factor in your case would be the nutrients. Your new growth at the top is literally sucking the mobile nutrient elements from the lower leaves. Either your root system isn't established enough to uptake the required nutrients or your lighting is powerful and it forces the plant to grow vigorously while it can't cope by uptaking the nutrients fast enough. In my hydroponic system, I would usually increase the nutrients if faced with a situation like this.

I search up phosphorus deficiency it does look like it I might do light feeding for it hopefully it will look better should I use one of these to add phosphorus ?

I’m running currently just led 35 watt Honeywell can I use this lighting throughout veg stage atleast I was thinking using sunlight during flowering or mid veg instead any advice?

For veg, maybe

Oh man, I got reprimanded by soil growers in here for giving advice on soil while I only grow hydroponics and yes, they have a point.

I don't know about Miracle Gro soil and their slow release of nutrients (or as someone in here said, they release nutrients when you add water).

All I can do is share an old grow photo of mine having these symptoms but they were more severe and for me, it turned out to be a nutes deficiency. It started with one lower leaf, then the second one and it just kept progressing. Here's is the photo (note this plant looks strange because I topped it very early):



It may be a PH issue for you that's locking out some element uptake.

Where I live, 1.5 cubic foot bag of Ocean Forest goes for about 15$.
First pic is a dry fertilizer, so don't get that. Second pic seems like a good option, but I can't read anything on the bag

Lucky you. Local nurseries and even Amazon it's $35 around here

Yeah I’m gonna check the ph once I get home this is what I got in the internet when I sewrch it up very similar to mine I could be wrong

Yes it's very similar, that's why I suspected it's a phosphorus diffeciency. Anyway, hopefully it's just a PH issue with you. Keep us posted.

Ok I cut those leaf that had those yellow or brownish so wouldn’t waste energy I did some topping now the new bottom leaf has these just 2 of them so far everything is good

Hey this is my progress should I trim or defoliate
