It's usually indicative of Nitrogen deficiency. Give them a good feed of Veg nutes.

is a pic possible??????????

are you indoor or out??????????

in pots????????? what medium??

or in the garden??????? soil type???????????

right now

imo

TLC

give them a flush with pure water

Ph correct pure water to between PH6 and Ph7. if needed

just keep pouring pure water in the top of each pot, fast nuff so the pot fills but does not ouerflow

at first the water will runn from the bottom of the pot quite dark in colour

ok

after some time the water runs out the bottom of the pot clear

stop

now return to your normal feeding gradually

at 1/2 strength frist day

then full sterngth next day

Crucial

the grow room temps what are they????????????

 

must keep them low of course you know

and humidity same

irey

 

i found a light spray of K will help a plant deal with shock

have you got any Eco-Carb ???????? its the best and what the pros use

or try a liquid Kelp spray

apply at half the recomended strength

and strictly at the beginning and end of the light cycle

 

same as in the garden

plant dont love water pon their leaves in full sun light, or under lights

but at dawn and dusk its fine

Purple is stress related

and is often exicibited by K deficient plants

[stinky]

i had same prob but i had purple/red stripes running up the plant stem all the way around

i put it down to heat stress as the soil was verry hot in the pots(outside)

plants were 4 or 5 weeks old

was the first time i have seen it to

purple coloring if not a genetic trait of the strain is the plant producing cyocanthin pigments,purple. I dunno I'm goin back a while here but I think I can recall it is due to phosphorus deficency...Id say it was something to do with your heat problem, some sort of nute lock-out situation perhaps?

u may need a temp gauge in your grow room at the same hight as the plants tips

 

find out what the grow room temps are doing with a max/min thermometer

 

and keep the air moring in the room with an ossiclating desk fan

 

yes high temps will burn your babies and at the very least cause unnessary stress on the plants

ok so i have to 2x 300 exaust fans out 2x 250 exaust fans in plus a oscolating fan on the wall my way of thinking is all its doing is moving hot air around the room the hot air from the out let in not ecaping just going back into the room will the high temps cause the plants not to take up nuitrents what about if the water temp is to hot???? doing everething as normal it has worked b4
