Plethora of Problems ?

Long time smoker... First time grower.. so be as brutal as you want. I take constructive criticism well. My hopes of this first thread is just to diagnose some of my problems now and where i went wrong.

Didn't intend to pick up the hobby (germinated a seed I had of some Aurora Indica and started buying the essentials as it grew and here we are. Will definitely continue the hobby considering I have quite a bit more feminized seeds.

7th week of veg

Setup: 2x2x4
300w LED
temps stay between 75-81 F
Humidity around 25-35
Advanced Nutrients as the base

After reading some of the threads on here I feel as if it can be a number of different issues from some nute burn to underwatering, admittingly sometimes I didn't use room temp water (sometimes cold) etc etc. What I've noticed is most of the issues I have are with the first set of leaves. the bottom has been drooping for some time and is now starting to curl and today has started showing yellow fully on one leaf and the rest some yellowing at the tips(as you will see in the pics) but the mid to upper part of the plant does not droop at all? is this a light issue?

I've also noticed since I've started this plant that some of the fingers don't develop as fully as some of the others on the same leaf. Either I'll get this midget leaf right where the longest(middle) finger should be or I'll get this half fingers that look like it was chewed off but not really (i'll upload a shot of this)

Thanks for the help in advance.
Look forward to the feedback.

Also curious as to if the white buildup/deposits on Terra Cotta pots is harmful to the plant?

Maybe try lowering the fertilizer concentration.

When I see leaf stress I give water only or less nutes. Then wait for improvement and not water again until the pot is very light and dry.

And very low humidity will cause the plant to uptake more.

So you have to lessen the nute concentration to compensate or they will burn.

All great advice ^^^^
Id be doing it all

Thanks Michigan. I'll keep that in mind. Also what is the ideal humidity in veg?

I keep all my rooms about 50-60% RH but I run a perpetual garden with plants at all stages all the time.

You can get away with higher humidity in veg and lower in flower but Growers will have different opinions. Many here talk about VPD. Look it up. Vapor pressure deficit.

But I would never risk mold with high humidity in my garden and follow old school info.

Also our plants are quite adaptable to different ranges. I worry about too high humidity. Over 60% is when mold can grow. And high temps. I keep my garden lights on 75- 77 farenheight and night time 66 degrees at the lowest. These are canopy temps. Careful about cold root temps like from a basement floor. That can cause problems even if the canopy is in range.

Appreciate all the insight! VPD will do.

This.

You might want to up pot before flipping to flower as well.
