What do you make of this

Hello friends..here I have two clones that realy shot out some bright yellow..I have four all the same age and from same Mother..Im thinking of a nute issue but the others are not showing this..I use all Organics in soil with exeption of Tiger bloom..I was watching these for the last few days and they are still growing the same speed..Just thaught i would share and see what you all think..Thanks

those are real nice man. I got to try the clone thing.

Hey man, that looks like a textbook early iron deficiency to me, why its happening to only two is beyond me... Sometimes I think when some clones are acting up over others I figures that area of the plant I took the cutting from must have been low in certain nutes (from like nutes available in certain root zone or whatev) so maybe thats the case here?

Anyways, weird man, I def. think its a Iron def., everything about it is baffling though, good luck man!

I am clueless on why that would do that. Maybe a goofy batch of soil?

Hello 4u2

I get something similar quite a bit growing outside or in a greenhouse.

This picture is caused by temprature changing from cold to warm, cold nights and warm days.

Some varieties, like equatorial sativas, don't take well to cold weather.

If you can keep the roots warmer, the plant will be able to take cooler temps than it otherwise could.

What are your daytime and nightime temps?

Is the floor cold?
