So me AGAIN LOL my hap hazard apporch has back fired and I now have a stunter sick plant I thing well I know it's stunter I now have yellow leaves

What could cause it
Set up is appalling really
Light is a ufo 90w about 70cm above
Pot is a drilled 5gal
Fed mostly water tiny bit every day(porbs my problem)
I did feed it some baby bio plant food was about 3 drops in 4 pints of water(probs may other problem)
Ph is around 6.3
Topped at 4 nodes
Age is 39 days old
Medium is potting soil generic brand
I now have yellowing fan leaves at the bottom
I'll upload some pics very soo.

Its needing feed or light is 'probably' your issue. .
Did the potting soil have any nutes in?
If not, your plant will begin eating it's stored nutrient (leaves yellowing) so you'll need to get some suitable nutes, even a poundland tomato feed will do for now but consider 'proper food' (that takes veg and bloom into account!)

Light needs to be nearer half that distance (its so underpowered it'll likely not harm plant!) But keep the radius as tight on plant as possible.
And pretty much same scenario with light, given the power and distance its likely not enough so the lower leaves are sacrificed for the plants greater good ("Greater Good!")....
Consider a 50 quid/doller ebazon blurple to support the UFO you got, it may grow on the UFO but is 'meh weed' what you want?

All this is just IMHO but good luck..

Ph might be too low depending on your starting soil Ph. Its always just better to foolproof it by adding in dolomite lime in the soil before you plant, or water with dolomite lime in the water. I buffers pH so no matter how much ferts you add it will keep pH stabled at 7 and you can avoid lockout. Trust me, soil doesn't NEED to be at 6.3 for cannabis, it does as good if not better at 7 too, especially for newer growers. Be sure to add a complete fertilizer and not just npk. temp should be 25c/77f

To note that UFO may be rated at 90 watts, but in reality only draw about 50%,, or less.

Sorry but adding dolomite lime just in case is also asking for problems plus the time it takes to break down ., your problem is with starting with generic brand soil , In saying that you can use it as a base to build a very good soil . I do .

Any chance of a recipe mate
Also if I was to repot should I go up in size

If it's auto and you can keep 80 degrees in ur space plant directly u will get much better results also autos don't like being transplanted and a directly planted auto will grow quicker and larger if all things are equal.

@Newgrow31 If you go to the Organic threads you will find a heap of info on soil ,
