Deficiency Problems in flowering?

Hello

I normally wouldn't do this. but a few of my plants aren't doing so well and would like to prevent further damage.

Here is a picture of the leaves that is affected. The only plants that are effected (2 of 6) are the ones that are very close to the light. The leaves are drooping, crusty, and have literally no trichromes compared to others. They also have a slight color problem.




Heat is an not an issue, ph fluctuates from no less than 5.4 to no greater than 6.3 (usually 5.6 - 6.1) in the two week drain and replenish cycle.

The setup goes as this - 1 400w HPS with 2 65w flowering CFL and 2 45w veg cfl. The tent is PACKED with 6 seperate buckets, and a net that I was going to incorporate scrog with but found out I understood scrog all wrong after it was too late. I am using AN jungle juice (lucas method) I am about to begin flowering week 5.


Some of the plants have much healthier leaves.

Earlier today I raised the hps to its maximum potential about 6 inches higher, also I added 10ml more of my ca/mg supplement to each bucket. Maybe this would do the trick.

If anyone could help it would be greatly appreciated

"the claw" is indicative of N toxicity. are those leaves papery, or is it just the pic?

Yes very papery, but only the ones that are clawlike. I haven't really altered my nute regimen since the start just the same 1:2 ratio the lucas method asks for.

Thank you for the response

How close it the 400 watter from the plants?
I doubt it from the light or heat too. It looks
more like nute burn what your ppms? I go by
ppms not by cap full or tsp or whatever!

The ppm rises from 1100 to about 1500 in the two week cycle as I continue to have to top off the buckets with more nute water. The 400w was about 4 inches away laterally to the worst plant, and was equal if not above the light a little bit.

I was wondering since technically that plant would be taking in the most lumens since it is the closest - wouldn't it need more of a nute % than the others.

nope. only thing is it may need more water if its in a hotter area of the room.

what are u doing for cal/mag? those rusty spots usually scream lack of cal/mag. the really dark green usually screams too much Nitrogen. and the brittle leaves could be part of either of those problems, or also ph, temp, nute def

remember less is more, and its always going to be easier to add more nutes if needed, infinitely harder to remove extra nutes that have already been added.

good luck!

It looks like stress from the light too close. What are the temps?
