answered grow question 5y ago
can be a cal mag deficiency, but before check your ph (has to be something like 5.8) and the power of your light (too close/ too much power etc)

I think it was a cal mag and everything else too. I believe I was just under feeding them. Thanks for the help

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto
Week 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Heat stress? Light stress? Nute burn?
Hi y’all Since my girl started to flower the top leaves near bud sites have this weird cupping downwards look. I doubt it might be a nute burn since I already gave her a good flush. I think the heat might be the main issue (86-87degrees during day). What do u think? Day38autoflwr

leaf problem?
Just found one of my top leaves turning yellowish, during flower. Just wanted to make sure if it’s the normal behaviour that I should expect or some kind of deficiency? Rest of the plant looks good

Big difference in first true leaves' size
Big difference in first true leaves' size Its almost day 5 after emergence. Is this normal? Should I be concerned? ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Weird leaves
Leaves slightly deformed because they were hitting against one side of my tent, but on the other hand, their colors have lighter areas and others darker. Is this due to sweating or is it a deficiency? Have a good day everyone and thanks for your answers!
