have more and better pics but a hell to get them out do somebody have a easy way to do it?

Here a cheat sheet I use. ient Disorders To use the Problem-Solver, simply start at #1 below. When you think you've found the problem, read the Nutrients section to learn more about it. Diagnose carefully before making major changes. 1) a) If the problem affects only the bottom or middle of the plant go to #2. b) If it affects only the top of the plant or the growing tips, skip to #10. If the problem seems to affect th entire plant equally, skip to #6. 2) a) Leaves are a uniform yellow or light green; leaves die & drop; growth is slow. Leaf margins are not curled-up noticeably. >> Nitrogen (N) deficiency. b) If not, go to #3. 3) a) Margins of the leaves are turned up, and the tips may be twisted. Leaves are yellowing (and may turn brown), but the veins remain somewhat green. >> Magnesium (Mg) deficiency. b) If not, go to #4. 4) a) Leaves are browning or yellowing. Yellow, brown, or necrotic (dead) patches, especially around the edges of the leaf, which may be curled. Plant may be too tall. >> Potassium (K) deficiency. b) If not, keep readingâ?¦ 5) a) Leaves are dark green or red/purple. Stems and petioles may have purple & red on them. Leaves may turn yellow or curl under. Leaf may drop easily. Growth may be slow and leaves may be small. >> Phosphorous (P) deficiency. b) If not, go to #6. 6) a) Tips of leaves are yellow, brown, or dead. Plant otherwise looks healthy & green. Stems may be soft >> Over-fertilization (especially N), over-watering, damaged roots, or insufficient soil aeration (use more sand or perlite. Occasionally due to not enough N, P, or K. b) If not, go to #7. 7) a) Leaves are curled under like a ram's horn, and are dark green, gray, brown, or gold. >> Over-fertilization (too much N). b) If not, go to #8â?¦ 8) a) The plant is wilted, even though the soil is moist. >>Over-fertilization, soggy soil, damaged roots, disease; copper deficiency (very unlikely). b) If not, go to #9. 9) a) Plants won't flower, even though they get 12 hours of darkness for over 2 weeks. >> The night period is not completely dark. Too much nitrogen. Too much pruning or cloning. b) If not, go to #10... 10) a) Leaves are yellow or white, but the veins are mostly green. >> Iron (Fe) deficiency. b) If not, #11. 11) a) Leaves are light green or yellow beginning at the base, while the leaf margins remain green. Necrotic spots may be between veins. Leaves are not twisted. >> Manganese (Mn) deficiency. b) If not, #12. 12) a) Leaves are twisted. Otherwise, pretty much like #11. >> Zinc (Zn) deficiency. b) If not, #13. 13) a) Leaves twist, then turn brown or die. >> The lights are too close to the plant. Rarely, a Calcium (Ca) o Boron (B) deficiency. b) If notâ?¦ You may just have a weak plant.

thanks man.. it may be Over-fert but can a ec of 1,8 lead to that? my previus strains did have higher ec than that i have now. growing mt cook now i did grow mk ultra and had ec up to 2,4 and it did fine oh i miss that strain.. some new pics toAttachment 273459Attachment 273460Attachment 273461Attachment 273462

As far as your Hydro system and what PPM/PH/whatever,.... I can't help you as I grow in soil, and know next to nothing about hydro. :o

Looks N starved to me, but a lockout isn't out of the question in Hydro. Good luck bro! Hopefully one of the Hydro guy's can spot this thread and set it strait!
