Hi everyone
I’m new to this and probably have done everything wrong so far or mostly.
I’m growing skywalker og in a 1.2mx1.2m tent I made with a 600watt led viparspectra
I’m growing in 20 litre pots from start,to big I know now!!couldn’t water till run off because scared to over water I’m in coco 70% perlite 30%.im using bio Diesel nutes I’m in 3rd week of flower but I think iv given to much phosphorus last water top leaves are twisting a bit and tip of leaves are slightly going yellow??
Only can water every 5-7 day cause pots are sooo big😩
Do they look ok? And am I going to have trouble with never having any run off?

You look good. You can water to runoff with a 20l pot and coco. You can’t really over water coco unless you deliberately try.
Ok then thanks heaps for the reply
Was a bit worried about run of because I’ll have to give them about 6 litres each.
There are only two plants and I’m watering them 3-4 litres each with no sight of run off and they still take 5-7 days to dry out on top?
Another question when should I stop using cal/mag?
I’m currently using 1ml/litre?
Wait till they dry out all the way and then water to run off. I use cal mag every watering till the end. It’s really important with coco because it naturally absorbs and holds calcium.
That makes sense. I water about a 1/2 gallon for a 3 gallon pot.

most cal mag contains nitrogen, which one tries to taper near the end of flower. There are some (like earth juice oilycann) that have zero nitrogen.
If it were me I’d stop adding calmag by week 5-6 of flower. If you find deficiencies there are products you can use individually that don’t contain N.

I use it till the end since the quantum boards really put the plants into over drive. Most folks do taper it off at the end.

Screw them. They want people to fail. Better for business. Keep the course. It most important growing tool are your ears. From the looks so far, you’ll be happy with the results.
