ive cracked open the big tent to do another jh grow, but it aint all plain sailing.

i had them under my 250w veg light under the workbench in my garage and all was going good, 2 or 3  weeks ago i moved them into the big tent

and since thye have started yellowing and the leafs are canoeing, it aint heat stress as its cold out there and it aint went past 26c max at canopy level.

one thing i did do is turn on the propane greenhouse heater at the same time so its kinda fkn my head up

ive always put the feed in at 5.8ph with sometimes 5.6 or 5.7 when early vegging but ive since read this may be too low

oh they are in 20l pots of canna pro coco, 20% run off everytime , 

early veg they had 0.5ml pel ltr canna coco a+b and 1ml per ltr rhizotonic

went up to 1m  per ltr after a cpl weeks

then up to 1.5ml per litre about the time i moved em

whats strange to me is the leaf tips look like nute burn but im putting it in about 1.1 and its coming out at 0.3 !!!

any ideas

Hmm could be a few things

No need to go below 5.8, I prefer 6 meself but it looks like heat damage starting, have you light closer now its colder then added a heater

Are the tips brown or yellow they sound underfed massively with run off (do we know everything is calibrated right at mo) and leaves start to yellow at tip but can look like burn as they yellow then start dying and getting necrotic and then rest of leaf follows.

They not so bad but if your tools are all calibrated right they need feed upping are you in hard or soft water area as well

light stress going from a 250 to??  and cos it cold you brought the light to close to soon?  what strain is it ? and you want you run off to be almost the  same as what goes in

[Roy Cropper]

If not heat stress then maybe light is to intense ? You mention a propane heater, could this be drying out the air ? Like is humidity too low ? Same as beefy I can't open the pics so I can't see to much

ec meter is a bluelabs one and is spot on, ph meter is calibrated evry cpl of days

250w to twin 600w hps in a 2.4mx1.2x2 tent

 

lights are about 22 inches away from the canopy, def not heat stress as i have a probe each side on the top buds and as i said never went over 26c

i have a humidifier in the tent, floats about 50 with lights on, 55-60 lights off, humidifier comes on with the lights

 

i was thinking co2 levels could be too high but i aint got any way to measure it
