Grow Questionsnutrient deficiency?

nutrient deficiency?

Dwckanukstarted grow question 4 years ago

My bucket went very low had to top up with RO water and observed a nutrient loss of 400. Just wondering if this looks more like a nurient deficiency or a fungus problem. All help is always appreciated Tip of other leaves affected are lower down and outside no top leaves.

HEY Kanuk, I think adding in the ro water drastically lowered your calcium..You're getting the rusty spots where the leaves are touched by light? I'd re boost any calmag into the system and hopefully the problem will stop spreading. Calcium and magnesium work hand in hand so doing a dual supplement should fix things up right and tight if your ph is in the right zone.👍 Happy growing

Maybe a ph spike causing calcium deficiency do the new growth leaves have the same? If they don’t you should be back on track

Hi, I understand you use a reverse osmosis? Also do you use calmag? Because it looks a little like a early calcium/magnesium deficiency.

Yellow Tips Hey all anyone knows what this can be? She had trips and I put to much neemoil on the leaves that's why she looks like this with the leaves. But since last week the tips from the top started to get yellow. I didn't use nutes till now and I dimmed the light to 60% / 70cm distance.
