Brown spots and yellowing on leaves

First grow
6 weeks autoflower lemon haze
soil is ffof
18/6 of light
ph is 6.7
Using gh floranova nutes at 1/4 strength

Plant is only 6 inches high and it's not root bound from what I can tell from the pot which is small maybe a gallon pot. I didn't realize it was an auto and found out to late for an up pot. Any idea on the deficiency with this plant? Thanks

Looks to me that it needs more Mag and Phosphorus

Ok thanks well I've been giving it bloom nutes and recently added cal mag into my water

Well she doesnt look so good. Week 7 on my auto after i flushed it 4 days ago. Not sure what i did wrong on my first grow. I know i started in a small pot(Didn't realize i had an Auto flower) My PH Runoff was about 5.5 so after my flush it was 6.6 and PPM was at 480 and now its 220 ish. My problem is all the Nute deficiencies can be very similar. Any advice on my next grow?

My photo was a male but it was bushy and green, looked great but its started to get light green patches on the dark leaves. Not sure what that was. I'm still learning but any advice would help TY

Yes put it in a bigger pot

sorry but thats not cal mag issue at all

how often are you watering and how often are you feeding ?

your leaves are tacoing bad.. but worst they are tacoing and your outer edges are back curling ... so i assume whats happening is every time you water the plant your putting food in that water aren't you?

No my watering are just PHed using tap water uncapped for 2 days reading only 80 ppm. I would feed,feed, water

It's a small small pot so every 3 days it needs water. So I would feed it 2 per week than water. Probably only takes about 1/4 gallon of fluids each 3 or 4 days

so your feeding 2x a week? feeds should only be done in soils once a week... but your leaves are tacoing and curling so somewhere your getting salt build up... generally that happens because they aren't getting enough fresh water and the first signs of salt build up are the leaves curling and spots ... are you mixing chemical lines? or is everything you use from the fora nova line?

i would cut out one of the feeds... even if your uncomfortable doing it bump your once a week feed up to 1/2 ... then don't ever do anything but water after that. whats happening is your plants so small it really takes such little food so your over feeding and the waste the plant doesnt eat is building up in the soil.. one water a week won't flush the waste enough from the roots... so you keep slowly building and building waste up. i know its hard to believe but the plant doesnt eat or want to eat chemicals all the time it wants clean water more than food.

You are right didn't even think about salt build up, my thinking was "hey 2 feeds a week bigger buds".. what about the size of it? I just cut it down. 16 grams wet maybe I'll get 3 grams.

hehe yeah maybe... you should have just taken the time to flush it it would have rebalanced and maybe gotten a bit better
