Brown black spot crispy edges
lovely_neighboursstarted grow question 3 years ago
I need help! Northern Light has Reddish brown spots turning dark-gray and crispy dark edges on the top leaves! It looks like a different issue from week 6 where gray spots appeared on the bottom leaves? Any ideas? Thanks

Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

Dry yellow tipsI've noticed a few leaves have developed some dry tips on the ends including some of the new ones coming through. Can anyone tell me what could be the problem? Feeding bio grow 2ml per l at the minute. Is it a deficiency of some sort? Or nutrient burn? Worth sticking to water?

Bruising or nute problem?I do not have enough characters here, please check diary for details. Some tops are showing some problems. The thing is, only a few and it does not seem related to light distance. My first thoughts is this is bruising, but I would like some more expert opinions.

New growth with yellow on the leaf edges is spreading. I have moved the lites to 12", the only change has been from using distilled water for the 1st 3 weeks then started using filtered well water (high sulfur & iron content) Should I switch back? Where to buy?

brown tips on some leavesfirst week of flower, only one plant out of five affected, only couple of leaves close to the top affected (up to 5 in total) - my assumption is 1. too close to light (I have 40cm between 400HPS which seems enough), PH problem or deficiency (potassium?)

Bottom leafs getting dryThe last two pictures show some sights of deficiency after getting a little bit dry before repotting. Any recommendations: should I do something? I will definitely use some ph-down and water with 6.0 to 6.5 ph to help the microorganism get going :)

Brown Spots on LeavesI've got some brown spots showing up on the Wedding Cake leaves, first thought it may be mold but it doesn't rub off and I sprayed both plants with neem oil about a week ago just in case. Could be CalMag deficient? I use RO water with about 150-200ppms in 3 liters once a day.
