Deficiency discoloration?
GrowBrosInc
started grow question 6y ago
I noticed some light de-coloration on the tips of one of the tops. Is it just because its new growth or do I have a deficiency? Thanks for the feed back.

Looks like the start of a cal mag deficiency or a ph problem makes sure those 2 are in line and you should be fine.

Not normal, maybe a magnesium deficit

That’s not normal, could be magnesium deficiency but I can’t be sure. How much Mg are you giving to the plant? It should be between 50 and 80 ppm

Cal/mag maybe?
Hey team, Please review day 19. Is this a cal/mag concern? I run a DWC with RO water mixed with nutes. Thank for your insight.

Lower leaves turning pale/yellow/brown
For the past four weeks the lower fan leaves on my plant have been getting pale green then yellow/brown. the stems have turned purple and I have noticed the last week or so the tips of the leaves have been slowly turning brown. Should i worry at this stage of growth?

Yellowing leaves - now made a diary
This week is where i noticed the yellowing taking effect on more leaves. Previously the only leaves that yellowed were the very bottom leaves due to lack of sunlight

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

Nutrient lock out?
Well watered my plants with great value drinking water. Ph 4.11. Didn't check ph until week 3. Currently upping it to 6.5 after I found the issue. Does this look like nutrient lock out? They were in root Riot starter plugs. And I fed the some clonex and great white microbs.

Unser erster Grow! Wir haben Nährstoffbrand, wie schlimm? Was können wir noch tun? - Dünger: Canna Terra Vega - Erde: COMPO SANA Qualitäts Eerde - 50%
Exactly one week ago, we noticed a nutrient burn. The symptoms were initially quite mild, with a few yellowing tips. Now it looks like in the pictures. We already watered with pH 6.3 water without nutrients in the next watering. What else to do?

Yellow leaf tips and edges
Hi I've got a problem that I've seen from the start of my grow and it's getting worse on older leaves now - zoom in edges and tips are turning yellow. I thought it was magnesium so I've dosed with Calmag but it's not improved - I'm Ph6.5 - any ideas?

EC too high and leaf yellow
EC 1.45 and some yellow leaf… I adjusted the soup by adding water to it and the new leaves seem to be pretty ok. Otherwise, all other parameters are good. It’s odd bc I followed instructions of the brand (Platinium Hydroponics) and the EC lvl is still kinda high. Suggestions?
