[hotshotisdashit]

Hey RIU. Got a lil problem here with one of my girls. There are 4 plants in my 3x2 tent. 2 are White Widow auto, 1 Northern Lights auto, and 1 Auto Wappa. The WWA is the one that's a lil sick. None of the others are having problems. Its started a few days ago. Im hoping someone here can shed some light on my problem and help my ailing baby. Here are some photos and some plant specifics. This is only my 2nd grow (my first was dwc) so any help will be greatly appreciated.

Plant Age: 19 days from spout
Plant height and width: 6 inches tall and 10 inches wide
Medium: Happy Frog Soil 60% and Perlite 40% in 2 gallon air pots
Water: Tap ph'ed to 6.5 going in and 6.3, 6.4 runoff . Water every other day.
Nutrients: Gh Micro, Grow, and Bloom .Have only given one dose at 16 days old. The girl had seemed to have a slight brown tips. She was a lil droopy so I decided to feed her. She perked up right away.
Light: Solar Storm 440 Led currently in veg mode and about 20 inches above canopy.

I you all need any more details feel free to ask and ill provide... C'mon help a brother out. lolololol.....

Personally never had that issue always have had high calcium well water where ever i live. I use technaflora MagICal to all the time. Do you have city water?

your might be feeding too early, the HF has some good stuff already inside, no reason to feed more, IMO

Deficiency. Pick up some Ca/mg

is watering a 19 day old plant every other day excessive? let alone watering till run off. I'm no air pot expert, but id be sure your pots r dry before watering. id also be sure your airflow is good also.

Yes I do have and use city water. N yes it definitely looks similar. I thought city water contains enough calcium/magnesium. Maybe I'll switch to reverse osmosis water n add cal/mag. Thank for the link.

Yea that's possible. But the leaf tips began burning before I fed. I only fed once when the plant looked a little weak. Do you think I should flush and wait?

The air pots dry out so fast. Plus I'm using 40% perlite which also makes it dry quicker. The top inch and a half is dry in these two days. Can this problem be caused by over watering?

idk what works for anyone else, but i dont feed until the 3rd week of veg or i see the 3rd node.

Those leaves look over-watered (swollen and downward curling). Wait until the pot feels light. Even with the 40% perlite, I don't think 2 days is enough for a pot to dry up. Over-watering can drown roots/ lead to root rot which in turn, leads to deficiencies.
