First time grower seeking help

[Blu3s94]

First time growing, gowing in soil using foxfarms.

Only using water and adjusting PH beforehand. These plants are 34 days old. There are some white and brown spots forming on the leaves. Mainly white, it is not powdery when touched. I looked under the leaves for pests but didn't see any. I did see a small critter in the soil?

What is this and what steps should I take? Thanks

What light are you using and how close is it?

I had thrips last year & those look kind of like the marks, can you zoom in? Also looks like it could use some magnesium or maybe time to start feeding it nutes lightly

Edit: Nevermind zooming in I see it in the other picture, you may have more than one thing going on but regarding your question about the white dots, have you searched under the leaves with magnification?

mmmm, lot going here..
your going to have to list your set up with temps humidity etc.. for good help..
plants are stunted and are suffering!

Using a California lightworks solarsystem 275

34" away from top of plant

Damn those are dark green how much nitrogen are you feeding those fuckers?

I have not used magnification

Never fed them anything? Just using hydrofarm soil

Not familiar. They just loook SUPER Dark green which suggests high nitrogen :D

Looking again i think its just the lighting of hte blurple.

Temp is 75°
Humidity is 46%

Soil mix is to hot plus the drainage do you water till 20% run off and do you leave your plants sitting in run off in the drip trays ? Od

Just curious if you backed the light off recently?

There is also likely nutrient issues as suggested.

Just by the pattern and location it would appear light burn would be part of the issues.

Could be wrong won't be the first time.

The lights are preset at 100%. So its possible they are light burnt?

I have been going with this chart for them.

I never water until runoff as I am not adding nutrients. Just using soil that has it in it.

Well there’s part of your problem the roots are to wet they need to be watered till run off occurs this will enable the plant to drain properly mate you need pot risers in your drip tray and get the pots up off the tent floor creat a air gap under them warmer dryer roots aids in plant health.

This ^^^

So you've got to start Feeding newts, you've got to start watering to run off, or what I do is feed, feed then every third watering I run twice the normal volume through of plain pHed water and record the runoff pH and PPM maybe something like that might work for you? and you also need to check for bugs, maybe thrips, good luck!

Appears light burnt to me. Maybe back it to 48" and slowly work up.

I agree you need to water to saturate the media. Being prefertes organic you want minimal runoff just enough to see it coming out. With synthetic we wanna kinda miniflush with runoff so nutrients don't build up. Then let dry very well before watering again

Also they don't list a recommendation for light cycle with those heights. Are you on 18/6 or 24/0

18/6

18/6

Yeah I would back it up a bit the leaves will stay bleached. But it should stop on new growth
