Possible Burn but unlikely..need other opinions.

Here is my Girl she is approx. 35 days old and still in Veg. I am using a 2ft 4 tube t5 for lighting. Just went on the Roots Organics feeding schedule..started at half strength and then went to 3/4. I don't think this is nute burn only b/c these "spots" have been on the plants fan leaves every now and then but the problem seems to be getting worse. Plus the leaves aren't shriveled up as I would expect to see from Nute Burn. However, this is my first grow so I need others opinions..but I don't see how I could get nute burn before even feeding the girls. Any help is appreciated. PH is roughly 6.1-6.3

That's not burn from what I'm seeing. One thing about nute burn is it doesn't really skip over leaves on the way up. There are times when one fork of the main stem will burn faster than others, but it will start at the very bottom of that fork rather than partway up. Ph 6.1 is too low for standard soil and the plants look like that's the problem. Try to aim for closer to 6.6.

Thanks mothers finest....I have NOTHING but problems trying to get the damn PH up on these things...problem was I'm a soil grower and the person that gave me the clones is a hydro grower so he doused them with nutes before I first got them...still haven't reached that magic number 6.5 but I"ll go for that 6.6 like you said. Again thanks.

Hey 420 try this link its a pretty good reference chart I use I dunno if will help you but you never know. And where were you stationed I was down at MCAS New River for my time in.

Kron, Semper Fi Devil Dog....have looked at that chat in the past and am thinking maybe a mg or mn deficiency...going to go with the simplest explanation first which is the pH and see if that helps..but thank you for posting and helping solve this problem.

Forgot to mention..was stationed in the stumps in CA...Again thanks

No Problem man, Semper Fi just subbed to your journal, I never made it out to the Stumps did Yuma for Desert Training but thats it.

Just remember that changing the Ph of liquids you give the plant won't permanently change the soil Ph much. Sprinkle a little lime on top of the soil and use plain H20 when you water. At 6.2, regular 7.0 water mixed with it could yield something near 6.6. Check the Ph of fertilizer mixes before adding.

Thanks mothers RE: the lime. I was using roots organics soil but I think it lacks that lime...I'm assuming I can get that at a garden store? Also I do check the PH of the nutes/water before I do anything and I've had to raise them both dramatically before I even feed the girls.
