Hi all

After the week where i have added the pk13/14 i have 2 plants that have a loads of dried out yellow leaves on them, few other plants that have yellow dots on them.

I keep my EC at 1.4/1.6 an my PH at 5.8 an checked this daily.

Running DWC system my temps where touching 30c but i have also got CO2 in the room that reading is just over 1500ppm.

What could be causing this?

Also am ready now to put fresh nutes in should i make them a lot weaker now on week 6 of flowering

I am using Canna products with the A+B plus the Boost, Rhizotonic and CannaZym

Any help?

Thanks

It's week 6 in flowering dawg.. you gotta let us know if you're following feeding schedule COMPLETELY.. I mean all additives.

It could be a light/heat issue or deficiency, hell while I'm speculating I'll go as far to guess nute burn although it doesn't look like it..

All of these ideas are just that.. ideas. Don't take any of that to heart man it might be something else.

Nitrogen deficiency you are in bloom and you stop adding nitrogen so your plant is sucking the stored nutrients from the bottom leaves.
How long are you flowering for?
Thats what most gardens look like when they are getting ready to be chopped.

well it might be the ph is off in yor soil or your water you are giving them. Or like you said it could be the new nutes you added, if it wasnt any different before and just recently changed what did u change about it?

you are fine dude. Late in flower your leaves are supposed to look like that. Its just your plant using the lower leaves as food because you cut out nitrogen at this point in the grow. I dont see anything wrong. Looks great. Thats why I tell growers not to trim the lower leaves your plant will use them as food later on in the grow.

Yeah you feed your plant a lot of nitrogen during veg and the first couple weeks of flower. yeah dude thats exactly what a a budding plant should look like when its getting ready to be chopped. SHe looks good keep up the good work.
