Plants turning lime green on top of the canopy.

Hey everyone,

Trying BioBizz nutrients and growing organic for the first time.

On day 24 of flower and have noticed the plants are turning a lime green colour on the tops.

Everything was perfect until I changed from my MH to my HPS then it started going a lighter green on the tops. Below the top of the canopy is a nice deep green. There are no spots or marks on the leaves, just pale green.

The odd leaf is yellowing and dropping off right at the bottom but not significant loss, presumed it was due to lack of light getting down there.

Just after some thoughts on what people think is happening and whether it's a problem or not?

Ph is 6.5, temps are 27c in day, 20c at night. Watering every 3 days with 3ml bloom, 1ml grow per litre. 250w HPS is about 10 inch away.

a 250 watter? it's fine. I have 400's that are 5 -6 inches.

Maybe just starving with such low feeds. Never used biobizz but those numbers seem weak. Whats the PPM?

Looks light light burn with the yellowing from top down, protected leaves staying green.

Just made up a batch of my feed, EC is 1.2 or 600ppm. What ppms do you run at during week 4 flower?

Not sure if organic feeds work the same as synthetic nutes, but still interested to know what other strength people run at.

Thanks Renfro. Appreciate your input.

Thats what I thought initially too, I was able to run my MH pretty close with no problems, changed to my HPS and didn't change height. I backed it off when I noticed anyway and seems not to have got worse. Buds are still developing nicely.

If it was light burn, would these leaves return to being normal green or will they stay pale green for the rest of the grow now damaged?

Thanks Boatguy!

Thanks man. She is defo looking good so far, covered in resin already and buds are looking big too. Has been trained a bit to get a nice even canopy and picked this pheno for it's huge side branching and strong indica characteristics. It's a NL#5 x NL#2.

Hopefully she will be fine, ive had plants much worse at this stage and they turned out nicely in the end.

Hope you have a successful harvest

Jet.
