DWC: Brown spots and pale leaves on the 2nd week
need4weedstarted grow question 3 years ago
What's up with these brown spots, is it calcium deficiency and slight paleness? Nutes: CaliMagic 2.5ml/gallon, MaxiGro 0.3tsp/gallon, RO water, total 0.9EC - res was changed 6 days ago. Should I worry?

Check your pH first and foremost. Then make sure your airpump is doing its job aerating the roots. If that's good just top off the res every day with pH'd water. Your EC is probably a bit high for a plant that small, but it will probably grow into it.. Always remember, if all else fails, do a complete res change. I also recommend some armor si and hydroguard. Armor si helps your plants get nice and sturdy and hydroguard protects your roots. Diamond nectar is also useful later on to help with nutrient uptake but its not entirely necessary.

I'll give her a res change soon if it gets worse, let's wait and see. Again thanks for your input!

I get a lot of bubbles in the res from 2 pumps and PH is quite stable between 5.8-5.9 with this last res change for 7 days now, actually the most stable I could get than my entire first grow. Perhaps this also could be the reason, the PH is not swinging to above 6 and not all minerals are being absorbed - although I heard stable PH + EC means you are spot on, don't know if this is true. Or a lockout due to the heavy feed (I'm actually doing 1/3 of GH recommendations).
Thanks a lot for the tips. I'm using Armor Si + Diamond Nectar (did not write it the question due to text size limits), but I cannot find Hydroguard here.

Need some advice for these seedlings - suspect it could be early cal-mag deficiency. Thoughts?These seedlings are growing with nicely but I have noticed some slight dis-coloration on the seedlings once the domes came during hardening, medium is moist and light PPFD is hovering around 220-250, avg day temps are 24c and night temps are 22c, using RO water.

Old/Bottom leaves is dying off at the edge ?So these are the oldest leaves my plant has, the rest is fine.The edges are dying off and i don't know why, can anyone help ? The Edges aren't really crispy/dry. Is it maybe too much wind ( Windburn ) ? The Plant is receiving a slight breeze and the leaves are all shaking a bit.

Too Much Light?I think I have severly stunted my girls. Maybe I am comparing too much to other growers. My light has been hanging at 29in at 100% which was the recommendation. I think I damaged them. Can they recover? I saw a diary with the same light/strain at a hang height of 30in @60% power.
