Hi guys!

Growing 3 autoflower plants in 70/30 coco>perlite medium, 15 liter pots a 120x 120 x200 cm grow tent. I have a 600w watt led light. Current humidity is 48% and ph reading for the water im giving them is 5.8. Feeding with growzilla 2 part nutrient with an npk ratio of 28.5.30.

Having a few problems with my plants and I was wondering if someone could help me out with identifying some of them. I have a darkening colour and roughness to the touch on the fan leaves, also the tips of the leaves are really bright yellow, there seems to be a few bite marks on some of the leaves and lastly I have noticed some brown blotches. Will upload photos of then as well. Thanks a lot for your time guys!!!. Btw this is the start of week 4.

thank's a lot for that, you reckon I just flush them and then continue feeding, but with a fertilizer with a lot lower nitrogen content?
 
getting an ec meter tomorrow for that exact reason. From what I have heard, the best level for the plants is supposed to be 0.8-1.2 ec?.and then once they get over 1.5 flush it out?. Sorry about all the questions, just first time growing with coco and indoors
 
Don't know specifically about coco's nute levels but I will run my RDWC system @ 1.2-1.4 ec during veg.
As always though, let the plant tell you what it wants.

Just run a little runoff each feeding, don't worry about flushing.
After they're established ramp the feeding (frequency, not ppm's) back up, they'll explode!
