Hi guys im new here, i hope this is the right place for my question..
I grow an autoflower, (RQS, Royal Cheese auto) its in the 2nd vegatative week i think.. nearly 4weeks after sprouting from the soil..
It keeps growing, but this week it started to show little signs that somethings wrong, this is my 2nd grow, im an amateur :D
I cant figure out because there are too many simptoms, im not experienced yet so i want to ask you guys wtf is wrong with my plants!

MATERIAL:
soil

LED:
mars hydro SP250 250W LED (now im keeping it on 60-65%% and aprox from a 20" distance.. i dont think its the light.. maybe the light is too weak even. anyway..

NUTRIENTS:
T.A. (Terra Aquatica) TriPart nutrients, i started to use them la week ,starting from the 3week from sprouting, whe the first true leaves did grow (a leave with only 3branches), and i used only 30% from the does, rthen when i saw first levaes with 5branches i upped the 30% to 50%.. it looks kinda anutrient burn, and this week i feed it only with balanced water nothing more, nothing less, because the soil has nutrients inside also..

PH:
i try to do steady 6.5 solution (GHE 1-5-0) Ph down

TEMPS:
min 17/18*C at night over the day (19/5) to 24-26*C, additional co2 is there because i live in the same rooms, small rooms, so co2 builds up very fast, but i dont think its related to co2..

RH:
trying to keep it 55-60%

first two pictures are from the last week, the others from yesterday.. it keeps growing fast, but.. there some signs.. what could this be? i tend to think i started the nutrient program too soon, because soil already has a lot nutrients from my garden.. but from the other hand it looks like a deficiency to me, i dont know guys, im an amateur, this is the second grow in my life.. i cant do any expertise, im confused..the leaves ar colored and some places the tips are like from nutrient burn..

btw the leaves are pointing down i think just because i took the photos when the day cycle tarted (i turned on the LEDs minutes before that), but thats only my opinion..

sorry for my bad england :D :D

Unhappy roots. What's your soil composition and watering habits? That soil looks pretty dry. What's the drainage situation for those pots?

the first to weeks i barely watered it because it was so small, a seedling you know? like 25-40ml in the first week from sprouting, 2nd week 50-75ml, 3d week aprox 100ml in that 3gallon pot, and now when its bigger i do aprox 300ml.. trying to do 1day in between and then 2days, 1day in between and then 2days in between.. i cant imagine how big the roots are, maybe many parts of the roots dont get enough water, i dont know, i dont have much experience.. the soil is from my gaden wher in summer other stuff grows shoudl be good i think, added 5% perlite, and the pot is with big holes, so the soil drys out faster and i cant overwater it.. i dunno if i did good with the ad20240315_164416.jpgditional holes..

Soil is drying out too quickly, that much im sure of.

I would consider watering to runoff once and see how she reacts, but she's not too bad, so maybe wait for some experienced soil growers to back me up on that.

im worried mostly about the dots on the leaves, but im underwatering her and she grows it just means she doesnt get anough nutritients from the roots right? without water for the roots the plant cant feed herself.. that would be the logic in this case.. hmm..

It's a complex set of variables. The soil moisture, PH, microbiome, root zone oxygen levels, ambient temperature, and nutrients all work together. It's not a super narrow needle to thread to have them all working in conjunction, but if one or two things move too far out of wack, it will cascade and throw everything off.

The roots and microbiome need water to metabolize nutrients. In my opinion, the biggest issue with Autos is that you can't prolong the veg cycle to allow these issues to resolve before the plant starts to flower. You aren't in that bad of a spot, so don't panic. Whatever adjustments you make, you have to give the plant time to adjust, too much too quickly will cause more problems and you won't be able to narrow down what caused it.

The leaves won't heal, but the plant will park up and gain some vigor when you've made the right corrections. Look at the plants demeanor new growth when judging overall health.

thanks a lot, i flushed it with plenty of water with runoff, will see how it will react to that the next few days!

You have the attention of some smart people. Listen to their advice. The plant should take off soon. Water once daily with your 50% till you get 15% or more running off, then once she starts drinking all that in a day water two or 3 times a day, don't up the feed strength.

Don't flush with plain water in the future if you did. Just flush with the proper or half strength solution.

yeah when i gave them the 1L each, the next 2days they just exploded and the stems are pretty big now also. tomorrow i will give them another 1L (i will let 2days pass in between again) i will continue to give them the same 30%, then 50% and stop by 50% will take a look for a week how she reacts to 50% if all will be good ,then i will give 75% from the dose.. why every day? people say to water it and let the soil dry out a little..when i put the 1L i water it 3times waiting for 30minutes, so all the soil gets the water so it does not just run out of sides or the bottom.. i have big holes in the pot, i posted a picture..

2 days is fine. The key is not increasing feed strength once you find what they love, but rather increasing feed frequency. I grow fantastic plants feeding the same thing from veg thru flower changing only feed frequency
