???? can you tell me wtf this is????

I repotted them into soil (plagron batmix) which i've used before with no problems and put them into flower. Its the older leaves that have this on them. The ph of the feed is 5.9 and the run off is the same

I've looked on the 'check this 1st thread' but i can't find anything the same

anyone?????

That actually looks like light bleaching to me. I have the same thing on a couple of my leaves from when I got them too close to the HPS. What kind of lights are you running and how far are your plants?

No it ain't bleaching coz its the lower leaves that have that on them. Thanks for the reply

looks like too much nitrogen

Cheeres mate that is a possibility coz they have been repotted into batmix which is high in nitrogen. good call. i'll back off the grow nutes. the new growth is a bit pale so i upped the nitrogen a bit, that coulda been a mistake

got excactly the same issue,, if u figure out 100% what it is let me know

I've just looked on another thread and it looks like calcium deficiency which the plant doesn't take up cal if its cold which my lights off temps can get cold. so it could be that. epsom salts cures it????

well i ve got epsom salts in my soil.. i ll try a tbs in a liter of water just in case this works i ll let u know.

don't think it's calcium (from rui plant problems and cures stickie) : Calcium Deficiency:
Young leaves are affected first and become small and distorted or chlorotic with irregular margins, spotting or necrotic areas. Bud development is inhibited, blossom end rot and internal decay may also occur and root may be under developed or die back. Deficiency will cause leaf tip die-back, leaf tip curl and marginal necrosis and chlorosis primarily in younger leaves. Symptoms: young leaves develop chlorosis and distortion such as crinkling, dwarfing, developing a strap-like shape, shoots stop growing and thicken.

I might not be cal def then. The growth tips are still growing ok so i'll keep doing what i'm doing. I've grown these clones before and i'm doing the same thing with the same nutes the same soil as before the only difference is its colder this time. I'll put another heater in and see if that stops it

easy mate lol. just trying to help sm4rt out with some rusting/bleaching out of a few of his leaves. found this site thought it might be helpful? take it easy bro

i bet my mother on it.. no worries.

i'd go with that... with the low ph i mean, no pro by a long shot but read up on ph 5.8-6.2 is the best for our flower, i've read up but dont quote me lol

Guys, it is a advanced mg def. Look at a lower leaf that just started the discoloration and it will be apparent. Calcium def. will develop spots.

Peace, Unity
