Burned tips
CRiSPrGrowanswered grow question 4 years ago
hey there ! so this is calcium and magnesium related deficiency. For magnesium you can tell from the yellowing happening at the serrated edges of the leafs. Calcium deficiency you can see from the rust spots starting to happen on the leafs away from the edges. Basically you need to replace the CarboLoad (molassess) with cal mag . this is starting to happen also because of the heavy light cycle, so it's probably a good idea to cut that down as much as you're willing to go. Hope this helps ! 🚀

Hi-
That looks like you've got a little potassium deficiency (K), and/or maybe some light stress too.
A good resource for identifying problems by photo is growweedeasy.com's "Plant Problems" area.

Hi buddy ;-) If you overfeed, I would proceed as follows. Best if you have osmosis water and mix the stale water for 24 hours (after 24 hours the chlorine has evaporated somewhat) to an Ec value of 0.2. Then add Cal / Mag until the Ec is 0.4. This is your source of water, so you can flush. At the next pour, start with a quarter of the feed dose.

Leaf tips turning yellow or brownIs it normal for leaf tips to start turning a different color? I thought maybe it was nutrient burn so I flushed it a few days ago.
I’m a total noob with growing so I’m not sure if they’re supposed to get better after a flush.

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency.
However, only the main cola is affected now. So I also suspect light burn.
What's your opinion?

LightingI have a question, on one of my sprouts it appears to have slight discoloration in the tips it looks almost white. It has been like that sense the seed shell came off. The others coming up look just fine but wanted to make sure it was not getting burned by the lights?
