Nah they're looking good, i agree with mac. You'll know when you have issues, the plants show symptoms.
for a 1st grow i wouldnt worry about a net it just gets in the way and i agree they look a little bit light try some fish shit in your water you can get it at walmart unless you have food already First check your PH
Looking ok, are you growing in coco that's what it looks like to me. Looks like you are growing in 3 gallon pot setting inside a bigger pot. If so that's good but coco needs to be feed with 20 percent run off if that's what you are doing. If not you will start to see some things down the road. If it is coco plants will grow super fast and be threw your net in a week.
Yes they are in coco, the pots are 49 litre. I have been doing run off and the pots are on legs so they don't sit in the run off until I empty it. I have been feeding ph around the 5.8 to 6 with about 600 ppm
only issue i see . Do you see the slight cupping on the upper leaves ? This is from the result of the light being too close . Just raise the light 6 inches . Light too close will also cause light green leaves not your issue . Only slight cupping . . Tell us what your feeding for veg .and what will you be using for flower ?
It all sounds good to me, when I ran coco I did 500 ppm and feed twice a day about your size of plants right now. ph anywhere from 5.5 to 6.0 is ok and the more you feed the faster they will grow. I was feeding my plants 4 time's a day and the growth was crazy. Using pump on a timer with halo rings around the plant to make it easier. But a lot do twice a day and get good results. Good luck show us your plants in two weeks and they should be double in size easy if you keep things tuned in.
Thankyou, I will raise lights. I am using grotek monster grow for veg and grotek monster bloom for flower plus calmag mixed in
Only advice i can give you . Continue the monster grow for the first two weeks of your 12/12 then switch to bloom. This will guarantee a green healthy plant through flower. I know the package will say otherwise . Package does not have 35 plus years of experience .
Here's the same auto 35 days into flower in promix and vermiculite and perlite with lime and gypsum, so same plant same age almost only thing different is the one was grown in coco and you can see how crazy it is the results coco will do if you know how to do it.
